In the “What type of data processing organisation” paper, we examined that you can build a data culture whether your organization consists mostly of data analysts, or data engineers, or data scientists. However, the path and technologies to become a data-driven innovator are different and success comes from implementing the right tech in a way that matches a company’s culture. In this blog we will expand the data engineering driven organizations and provide how it can be built from the first principles.
Not all organizations are alike. All companies have similar functions (sales, engineering, marketing), but not all functions have the same influence on the overall business decisions. Some companies are more engineering-driven, others are sales-driven, others are marketing-driven. In practice, all companies are a mixture of all these functions. In the same way, the data strategy can be more focused on data analysts, and others on data engineering. Culture is a combination of several factors, business requirements, organizational culture, and skills within the organization.
Traditionally organizations that focused on engineering mainly came from technology driven digital backgrounds. They built their own frameworks or used programming frameworks to build repeatable data pipelines. Some of this is due to the way the data is received, the shape the data is received and the speed of the data arrival as well. If your data allows it, your organization can be more focused on data analysis, and not so much on data engineering. If you can apply an Extract-Load-Transform approach (ELT) rather than the classic Extract-Transform-Load (ETL), then you can focus on data analysis and might not need extensive data engineering capability. For example, data that can be loaded directly into the data warehouse allows data analysts to also do data engineering work and apply transformations to the data.
This does not happen so often though. Sometimes your data is messy, inconsistent, bulky, and encoded in legacy file formats or as part of legacy databases or systems, with a little potential to be actionable by data analysts.
Or maybe you need to process data in streaming, applying complex event processing to obtain competitive insights in near real time. The value of data decays exponentially with time. Most companies can process data by the next day in batch mode. However, not so many are probably obtaining such knowledge the next second data is produced.
In these situations, you need the talent to unveil the insights hidden in that amalgam of data, either messy or fast changing (or both!). And almost as importantly, you need the right tools and systems to enable that talent too.
What are those right tools? Cloud provides the scalability and flexibility for data workloads that are required in such complex situations. Long gone are the times when data teams had to beg for the resources that were required to have an impact in the business. Data processing systems are no longer scarce, so your data strategy should not generate that scarcity artificially.
In this article, we explain how to leverage Google Cloud to enable data teams to do complex processing of data, in batch and streaming. By doing so, your data engineering and science teams can have an impact when (in seconds) after the input data is generated.
Data engineering driven organizations
When the complexity of your data transformation needs is high, data engineers have a central role in the data strategy of your company, leading to data engineering driven organization. In this type of organization, data architectures are organized in three layers: business data owners, data engineers, and data consumers.
Data engineers are at the crossroads between data owners and data consumers, with clear responsibilities:
- Transporting data, enriching data whilst building integrations between analytical systems and operational systems ( as in the real time use cases)
- Parsing and transforming messy data coming from business units into meaningful and clean data, with documented metadata
- Applying DataOps, that is, functional knowledge of the business plus software engineering methodologies applied to the data lifecycle
- Deployment of models and other artifacts analyzing or consuming data
Business data owners are cross-functional domain-oriented teams. These teams know the business in detail, and are the source of data that feeds the data architecture. Sometimes these business units may also have some data-specific roles, such as data analysts, data engineers, or data scientists, to work as interfaces with the rest of the layers. For instance, these teams may design a business data owner, that is the point of contact of a business unit in everything that is related to the data produced by the unit.
At the other end of the architecture, we find the data consumers. Again, also cross-functional, but more focused on extracting insights from the different data available in the architecture. Here we typically find data science teams, data analysts, business intelligence teams, etc. These groups sometimes combine data from different business units, and produce artifacts (machine learning models, interactive dashboards, reports, and so on). For deployment, they require the help of the data engineering team so that data is consistent and trusted.
At the center of these crossroads, we find the data engineering team. Data engineers are responsible for making sure that the data generated and needed by different business units gets ingested into the architecture. This job requires two disparate skills: functional knowledge and data engineering/software development skills. This is often coined under the term DataOps (which evolved from DevOps methodologies developed within the past decades but applied to data engineering practices).
Data engineers have another responsibility too. They must help in the deployment of artifacts produced by the data consumers. Typically, the data consumers do not have the deep technical skills and knowledge to take the sole responsibility for deployment of their artifacts.This is also true for highly sophisticated data science teams. So data engineers must add other skills under their belt: machine learning and business intelligence platform knowledge. Let’s clarify this point, we don’t expect data engineers to become machine learning engineers. Data engineers need to understand ML to ensure that the data delivered to the first layer of a model ( the input ) is correct. They will also become key when delivering that first layer of data in the inference path, as here the data engineering skills around scale / HA etc really need to shine.
By taking the responsibility of parsing and transforming messy data from various business units, or for ingesting in real time, data engineers allow the data consumers to focus on creating value. Data science and other types of data consumers are abstracted away from data encodings, large files, legacy systems, complex message queue configurations for streaming. The benefits of concentrating that knowledge in a highly skilled data engineering team are clear, notwithstanding that other teams (business units and consumers) may also have their data engineers to work as interfaces with other teams. More recently, we even see squads created with members of the business units (data product owners), data engineers, data scientists, and other roles. Effectively creating complete teams with autonomy and full responsibility over a data stream, from the incoming data down to the data driven decision with impact in the business.
Reference architecture – Serverless
The number of skills required for the data engineering team is vast and diverse. We should not make it harder by expecting the team to maintain the infrastructure where they run data pipelines. They should be focusing on how to cleanse, transform, enrich, and prepare the data rather than how much memory or how many cores their solution may require.
The reference architectures presented here are based on the following principles:
- Serverless no-ops technologies
- Streaming-enabled for low time-to-insight
We present different alternatives, based on different products available in Google Cloud:
- Dataflow, the built-in streaming analytics platform in Google Cloud
- Dataproc, the Google Cloud’s managed platform for Hadoop and Spark.
- Data Fusion, a codeless environment for creating and running data pipelines
Let’s dig into these principles.
By using serverless technology we eliminate the maintenance burden from the data engineering team, and we provide the necessary flexibility and scalability for executing complex and/or large jobs. For example, scalability is essential when planning for traffic spikes during mega Friday for retailers. Using serverless solutions allows retailers to look into how they are performing during the day. They no longer need to worry about resources needed to process massive data generated during the day.
The team needs to have full control and write their own code for the data pipelines because of the type of pipelines that the team develops. This is true either for batch or streaming pipelines. In batch, the parsing requirements can be complex and no off the shelf solution works. In streaming, if the team wants to fully leverage the capabilities of the platform, they should implement all the complex business logic that is required, without artificially simplifying the complexity in exchange for some better latency. They can develop a pipeline that achieves a low latency with highly complex business logic. This again requires the team to start writing code from first principles.
However, that the team needs to write code should not imply that they need to rewrite any existing piece of code. For many input/output systems, we can probably reuse code from patterns, snippets, and similar examples. Moreover, a logical pipeline developed by a data engineering team does not necessarily need to map to a physical pipeline. Some parts of the logic can be easily reused by using technologies like Dataflow templates, and use those templates in orchestration with other custom developed pipelines. This brings the best of both worlds (reuse and rewrite), while saving precious time that can be dedicated to higher impact code rather than common I/O tasks. The reference architecture presented has another important feature: the possibility to transform existing batch pipelines to streaming.
The ingestion layer consists of Pub/Sub for real time and Cloud Storage for batch and does not require any preallocated infrastructure. Both Pub/Sub and Cloud Storage can be used for a range of cases as it can automatically scale up with the input workload.
Once the data has been ingested, our proposed architecture follows the classical division in three stages: Extract, Transform, and Load (ETL). For some types of files, direct ingestion into BigQuery (following an ELT approach) is also possible.
In the transform layer, we primarily recommend Dataflow as the data process component. Dataflow uses Apache Beam as SDK. The main advantage of Apache Beam is the unified model for batch and streaming processing. As mentioned before, the same code can be adapted to run in batch or streaming by adapting input and output. For instance, switching the input from files in Cloud Storage to messages published in a topic in Pub/Sub.
One of the alternatives to Dataflow in this architecture is Dataproc, Google Cloud’s solution for managed Hadoop and Spark clusters. The main use case is for those teams that are migrating to Google Cloud but have large amounts of inherited code in Spark or Hadoop. Dataproc enables a direct path to the cloud, without having to review all those pipelines.
Finally, we also present the alternative of Data Fusion, a codeless environment for creating data pipelines using a drag-and-drop interface. Data Fusion actually uses Dataproc as its Compute Engine, so everything we have mentioned earlier applies also to the case of Data Fusion. If your team prefers to create data pipelines without having to write any code, Data Fusion is the right tool.
So in summary, these are the three recommended components for the transform layer:
- Dataflow, powerful and versatile with a unified model for batch and streaming processing. Straightforward path to move from batch processing to streaming
- Dataproc, for those teams that want to reuse existing code from Hadoop or Spark environments.
- Data Fusion, if your team does not want to write any code.
Challenges and opportunities
Data platforms are complex. Having on top of that data responsibility the duty to maintain infrastructure is a wasteful use of valuable skills and talent. Often data teams end up managing infrastructure rather than focusing on analyzing the data. The architecture presented in this article liberates the data engineering team from having to allocate infrastructure and tweak clusters but instead to focus on providing value through data processing pipelines.
For data engineers to focus on what they do best, you need to fully leverage the cloud. A lift & shift approach from any on-premise installation is not going to provide that flexibility and liberation. You need to leverage serverless technologies. As an added advantage, serverless lets you also scale your data processing capabilities with your needs, and be able to respond to peaks of activity, however large these are.
Serverless technologies sometimes face the doubts of practitioners: will I be locked in with my provider if I fully leverage serverless? This is actually a question that you should be asking when deciding whether to set up your architecture on top of a provider.
The components presented here for data processing are based on open source technologies, and fully interoperable with other open source equivalent components. Dataflow uses Apache Beam, which not only unifies batch and streaming, but also offers a widely compatible runner. You can take your code elsewhere to any other runner. For instance, Apache Flink or Apache Spark. Dataproc is a fully managed Hadoop and Spark based on the vanilla open source components of this ecosystem. Data Fusion is actually the Google Cloud version of CDAP, an open source project.
On the other hand, for the serving layer, BigQuery is based on standard Ansi SQL. Whereas in the case of Bigtable and Google Kubernetes Engine, Bigtable is compatible at API level with HBase, and Kubernetes is an open source component.
In summary, when your components are based on open source, like the ones included in this architecture, serverless does not lock you in. The skills required to encode business logic in the form of data processing pipelines are based on engineering principles that remain stable across time. The same principles apply if you are using Hadoop, Spark, or Dataflow or UI driven ETL tooling. In addition, there are now new capabilities, such as low-latency streaming, that were not available before. A team of data engineers that learn the fundamental principles of data engineering will be able to quickly leverage those additional capabilities.
Our recommended architecture separates the logical level, the code of your applications, from the infrastructure where they run. This enables data engineers to focus on what they do best and on where they provide the highest added value. Let your Dataflow and your engineers impact your business, by adopting the technologies that liberate them and allow them to focus on adding business value.

Updating Twitter’s Ad Engagement Analytics Platform for the Modern Age

The most insightful time you'll spend today!
As part of the daily business operations on its advertising platform, Twitter serves billions of ad engagement events, each of which potentially affects hundreds of downstream aggregate metrics. To enable its advertisers to measure user engagement and track ad campaign efficiency, Twitter offers a variety of analytics tools, APIs, and dashboards that can aggregate millions of metrics per second in near-real time.
In this post, you’ll get details on how the Twitter Revenue Data Platform engineering team, led by Steve Niemitz, migrated their on-prem architecture to Google Cloud to boost the reliability and accuracy of Twitter’s ad analytics platform.
Deciding to migrate
Over the past decade, Twitter has developed powerful data transformation pipelines to handle the load of its ever-growing user base worldwide. The first deployments for those pipelines were initially all running in Twitter’s own data centers. The input data streamed from various sources into Hadoop Distributed File System (HDFS) as LZO-compressed Thrift files in an Elephant Bird container format. The data was then processed and aggregated in batches by Scalding data transformation pipelines. Then, aggregation results were output into Manhattan, Twitter’s homegrown distributed key-value store, for serving. Additionally, a streaming system using Twitter’s homegrown systems Eventbus (a messaging tool built on top of DistributedLog), Heron (a stream processing engine), and Nighthawk (a sharded Redis deployment) powered the real-time analytics that Twitter had to provide, filling the gap between the current time and the last batch run.
While this system consistently sustained massive scale, its original design and implementation was starting to reach some limits. In particular, some parts of the system that had grown organically over the years were difficult to configure and extend with new features. Some intricate, long-running jobs were also unreliable, leading to sporadic failures. The legacy end-user serving system was very expensive to run and couldn’t support large queries.
To accommodate for the projected growth in user engagement over the next few years and streamline the development of new features, the Twitter Revenue Data Platform engineering team decided to rethink the architecture and deploy a more flexible and scalable system in Google Cloud.
Platform modernization: First iteration
In the middle of 2017, Steve and his team tackled the first redesign iteration of its advertising data platform modernization, leading to Twitter’s collaboration with Google Cloud.
At first, the team left the data aggregation legacy Scalding pipelines unchanged and continued to run them in Twitter’s data centers. But the batch layer’s output was switched from Manhattan to two separate storage locations in Google Cloud:
- BigQuery—Google’s serverless and highly scalable data warehouse, to support ad-hoc and batch queries.
- Cloud Bigtable—Google’s low-latency, fully managed NoSQL database, to serve as a back end for online dashboards and consumer APIs.
The output aggregations from the Scalding pipelines were first transcoded from Hadoop sequence files to Avro on-prem, staged in four-hour batches to Cloud Storage, and then loaded into BigQuery. A simple pipeline deployed on Dataflow, Google Cloud’s fully managed streaming and batch analytics service, then read the data from BigQuery and applied some light transformations. Finally, the Dataflow pipeline wrote the results into Bigtable.
The team built a new query service to fetch aggregated values from Bigtable and process end-user queries. They deployed this query service in a Google Kubernetes Engine (GKE) cluster in the same region as the Bigtable instance to optimize for data access latency.
Here’s a look at the architecture:
This first iteration already brought many important benefits:
- It de-risked the overall migration effort, letting Twitter avoid migrating both the aggregation business logic and storage at the same time.
- The end-user serving system’s performance improved substantially. Thanks to Bigtable’s linear scalability and extremely low latency for data access, the serving system’s P99 latencies decreased from 2+ seconds to 300ms.
- Reliability increased significantly. The team now rarely, if ever, gets paged for the serving system anymore.
Platform modernization: second iteration
With the new serving system in place, in 2019 the Twitter team began to redesign the rest of the data analytics pipeline using Google Cloud technologies. The redesign sought to solve several existing pain points:
- Because the batch and streaming layers ran on different systems, much of the logic was duplicated between systems.
- While the serving system had been moved into the cloud, the existing pain points of the Hadoop aggregation process still existed.
- The real-time layer was expensive to run and required significant operational attention.
With these pain points in mind, the team began evaluating technologies that could help solve them. They considered several open-source stream processing frameworks initially: Apache Flink, Apache Kafka Streams, and Apache Beam. After evaluating all possible options, the team chose Apache Beam for a few key reasons:
- Beam’s built-in support for exactly-once operations at extremely large scale across multiple clusters.
- Deep integration with other Google Cloud products, such as Bigtable, BigQuery, and Pub/Sub, Google Cloud’s fully managed, real-time messaging service.
- Beam’s programming model, which unifies batch and streaming and lets a single job operate on either batch inputs (Cloud Storage), or streaming inputs (Pub/Sub).
- The ability to deploy Beam pipelines on Dataflow’s fully managed service.
The combination of Dataflow’s fully managed approach and Beam’s comprehensive feature set let Twitter simplify the structure of its data transformation pipeline, as well as increase overall data processing capacity and reliability.
Here’s what the architecture looks like after the second iteration:
In this second iteration, the Twitter team re-implemented the batch layer as follows: Data is first staged from on-prem HDFS to Cloud Storage. A batch Dataflow job then regularly loads the data from Cloud Storage, processes the aggregations, and dual-writes the results to BigQuery for ad-hoc analysis and Bigtable for the serving system.
The Twitter team also deployed an entirely new streaming layer in Google Cloud. For data ingestion, an on-prem service now pushes two different streams of Avro-formatted messages to Pub/Sub. Each message contains a bundle of multiple raw events and affects between 100 and 1,000 aggregations. This leads to more than 3 million aggregations per second performed by four Dataflow jobs (J0-3 in the diagram above). All Dataflow jobs share the same topology, although each job consumes messages from different streams or topics.
One stream, which contains critical data, enters the system at a rate of 200,000 messages per second and is partitioned in two separate Pub/Sub topics. A Dataflow job (J3 in the diagram) consumes those two streams, performs 400,000 aggregations per second, and outputs the results to a table in Bigtable.
The other stream, which contains less critical but higher volume data, enters the system at a rate of around 80,000 messages per second and is partitioned into six separate topics. Three Dataflow jobs (J0, J1, and J2) share the processing of this larger stream, with each of them handling two of the available six topics in parallel, then also outputting the results to a table in Bigtable. In total, those three jobs process over 2 million aggregations/second.
Partitioning the high-volume stream into multiple topics offers a number of advantages:
- The partitioning is organized by applying a hash function on the aggregation key and then dividing the function’s result by the number of available partitions (in this case, six). This guarantees that any per-key grouping operation in downstream pipelines is scoped to a single partition, which is required for consistent aggregation results.
- When deploying updates to the Dataflow jobs, admins can drain and relaunch each job individually in sequence, allowing the remaining pipelines to continue uninterrupted and minimizing impact on the end users.
- The three jobs can each handle two topics without issue currently, and there is still room to scale horizontally up to six jobs if needed. The number of topics (six) is arbitrary, but is a good balance at the moment based on current needs and potential spikes in traffic.
To assist with job configuration, Twitter initially considered using Dataflow’s template system, a powerful feature that enables the encapsulation of Dataflow pipelines into repeatable templates that can be configured at runtime. However, since Twitter needed to deploy jobs with topologies that might change over time, the team decided instead to implement a custom declarative system where developers can specify different parameters for their jobs in a pystachio DSL: tuning parameters, data sources to operate on, sink tables for aggregation outputs, and the jobs’ source code location. A new major version of Dataflow templates, called Flex Templates, will remove some of the previous limitations with the template architecture and allow any Dataflow job to be templatized.
For job orchestration, the Twitter team built a custom command line tool that processes the configuration files to call the Dataflow API and submit jobs. The tool also allows developers to submit a job update by automatically performing a multi-step process, like this:
- Drain the old job:
- Call the Dataflow API to identify which data sources are used in the job (for example, a Pub/Sub topic reader).
- Initiate a drain request.
- Poll the Dataflow API for the watermark of the identified sources until the maximum watermark is hit, which indicates that the draining operation is complete.
- Launch the new job with the updated code.
This simple, flexible, and powerful system allows developers to focus on their data transformation code without having to be concerned about job orchestration or the underlying infrastructure details.
Looking ahead
Six months after fully transitioning its ad analytics data platform to Google Cloud, Twitter has already seen huge benefits. Twitter’s developers have gained in agility as they can more easily configure existing data pipelines and build new features much faster. The real-time data pipeline has also greatly improved its reliability and accuracy, thanks to Beam’s exactly-once semantics and the increased processing speed and ingestion capacity enabled by Pub/Sub, Dataflow, and Bigtable.
Twitter engineers have enjoyed working with Dataflow and Beam for several years now, since version 2.2, and plan to continue expanding their usage. Most importantly, they’ll soon merge the batch and streaming layers into a single, authoritative streaming layer.
Throughout this project, the Twitter team collaborated very closely with Google engineers to exchange feedback and discuss product enhancements. We look forward to continuing this joint technical effort on several ongoing large-scale cloud migration projects at Twitter. Stay tuned for more updates!
Marks & Spencer Aims to Bring a Third of business Online and Google Contact Center AI is Key to its Success

“Hello, Marks & Spencer. How may we help you?”
As one of the biggest and best-loved retail brands in the UK, Marks & Spencer (M&S) is known for the personalized service it provides to its 30 million loyal customers. For 135 years and in 57 countries around the world, M&S has worked to meet and exceed customer expectations for quality and service. Since the advent of the telephone, this has meant cheerfully servicing customers who call in to M&S branches or into their contact centers, no matter what their request might be.
“Retail is in a state of flux and M&S is transforming to better serve our customers so that we can compete and win. Automating calls into our stores with Google voice recognition gives us every opportunity to get things right for our customers and keep them coming back again and again.”
—Akash Parmar, Enterprise Architect (Digital Customer Engagement), Marks & Spencer
The company now has a goal of bringing one third of its business online by 2022. In order to engage more customers online, it has opened a new voice channel hosted on Google Cloud.
The company previously had switchboards in 13 different stores across the UK and Ireland (UKI), handling up to nine million calls a year. But as its retail offering evolved across multiple channels, it was becoming increasingly difficult to quickly and effectively answer customer service requests using an outdated switchboard model.
Customers might call in to order an outfit they had seen in a store, to inquire about returning a dress they bought online, or to recover a lost umbrella in a food hall. Each of these different requests required a different routing response from staff, and if the company didn’t act soon, it knew that the cost of managing the increase in call volume would lead to a significant cost impact. M&S decided it was time to make a technological leap forward to meet customers’ expectations in the new, omnichannel retail environment.
“Retail is in a state of flux and M&S is transforming to better serve our customers so that we can compete and win,” says Akash Parmar, Enterprise Architect for Digital Customer Engagement at M&S. “Automating calls into our stores with Google voice recognition gives us every opportunity to get things right for our customers and keep them coming back again and again.”
Boosting opportunities for customer engagement with voice recognition
M&S customers were used to dealing with their local store for anything they needed. But as stores were completely separate from the online business, customers weren’t able to purchase something they’d seen online by calling stores because the store staff didn’t have access to platforms needed to place an online order securely. For a company that places a very high importance on customer experience, this was unacceptable.
Akash Parmar, Enterprise Architect for Customer Engagement, was set a the goal by Chris McGrath, M&S Programme Manager, to ensure that the right channel and the right level of assistance was available to customers at any point before, during, or after purchase. Akash set himself the challenge of building a platform that could adapt to all of these channels and scale very quickly.
“We didn’t have the resources to build a speech recognition platform. DVELP removed that obstacle. It understood what we wanted to achieve and how Google Voice APIs and Twilio could get us there. Whatever we want, DVELP builds it for us. DVELP always presents options, never problems.”
—Akash Parmar
In 2018, Akash reached out to Google Cloud partner DVELP, one of the UK’s leading experts on the Twilio programmable contact center platform and Google speech recognition technology. DVELP recommended a Google Cloud-based natural language speech recognition platform that leverages the audio stream intent detection functionality in the Contact Center AI solution, Dialogflow, as the heart of an inbound-call-handling strategy. This strategy was designed to improve routing accuracy, give customers more self-service options, and increase analyst visibility into customer journeys.
“We didn’t have the resources to build a speech recognition platform. DVELP removed that obstacle,” says Akash. “They understood what we wanted to achieve and how Google Cloud Voice APIs and Twilio could get us there. Whatever we want, DVELP builds it for us. DVELP always presents options, never problems.”
Using Google speech recognition to improve customer experience
M&S wanted to use natural language to enable customers to speak and state what help they required rather than choose from a list of options. This would help them answer the millions of calls coming in and figure out what customers needed quickly.
In order to do that, DVELP needed to consider how best to address tying customer intent to actions, while maintaining flexibility. DVELP recommended the unconventional choice of not referencing intent in the application layer, but mapping the available actions to the information required to perform them. These actions were then used to build a “declarative dictionary” for the customer service team.
By focusing on actions rather than intents, the solution enables the customer services team to configure actions to intents in virtually any combination of key-value pairs. Leveraging the fact that Dialogflow can detect and respond to customer intents in real time, M&S has already reached 92% accuracy in translating customer declarations to actionable intents.
“With Google Cloud speech recognition and Contact Center AI solutions such as Dialogflow, there’s no information that we can’t make sense of. No matter where you call from, who you are, your age, your gender: you speak, and we understand.”
—Akash Parmar
Akash recalls that once customers became comfortable with the prompt, “in a few words, how may we help you?” they started providing simple, concise responses, and the customer learning curve quickly leveled out. At that point, Google Cloud speech recognition and Dialogflow took over. “The technology worked perfectly and the result was like magic,” says Akash.
“With Google Cloud speech recognition and Contact Center AI solutions such as Dialogflow, there’s no information that we can’t make sense of,” he says. “No matter where you call from, who you are, your age, your gender: you speak, and we understand.”
Enabling self-service contact center improvements with Dialogflow
It was important to M&S that contact center employees be self-sufficient in updating the platform to reflect changes in demand. They needed to be able to easily react to a spike in inquiries about a special offer, for example, without relying on the engineering team. At the same time, neither Akash nor the DVELP team wanted the staff to have to learn error-prone JSON inside contexts, or write responses in order to get necessary information from customers.
DVELP’s creative solution was to fill out the “Action and parameters” section of every intent. This is usually reserved for collecting information from customer declarations, but was also easily adapted to implementing custom key-value pairs. This is particularly helpful in making sure that the contact center is ready to handle new promotions as they arise. As sales and special events are communicated to the contact center from the head office, staff can program specific vocabulary directly into Dialogflow, thanks to Contact Center AI, ensuring that the M&S system is immediately ready to handle related customer calls.
Rolling out the platform to the UK and Ireland
In just a few months after going live, calls are being efficiently routed to the contact center and its existing customer service platform. At the contact center, staff can quickly and easily respond to customer requests, place orders, and process returns. Thanks to the natural language capabilities of Google Cloud, a simple customer request like “order the red children’s dress in the Bath high street window in size six” not only gets correctly routed, but provides data points for future personalized interactions.
Being able to accurately recognize customer intent 92% of the time after less than four months since deployment is an important milestone for M&S. With a concurrent 89% voice-to-text accuracy rate for Dialogflow transcriptions, M&S has rolled out the successful speech recognition platform to all of its stores in UK and Ireland and customer service contact centers.
Akash is so pleased with the performance of the new Google Cloud platform that he’s focusing on what new functionality he can add next to improve customer experience even more.
“We’re working on collecting product codes from customers using natural language so we can give them stock availability details,” he shares. “We also want to use Google Cloud to enable a more conversational experience when customers are searching for help or FAQs on our website. At the same time, we’re looking at Contact Center AI and Dialogflow to provide a virtual assistant experience for our webchat journey. Thanks to our new voice solution, we can clearly understand the key issues that our customers face on a day-to-day basis; the aim now is to start solving these issues through self-service and automation.”

How Go-Jek, Indonesia’s First Billion-dollar Startup, Improved the Productivity of Data Scientists
Go-Jek, Indonesia’s first billion-dollar startup, has seen an incredible amount of growth in both users and data over the past two years. Many of the ride-hailing company’s services are backed by machine learning models hosted on Google Cloud Platform.
Models range from driver
But senior executives at Go-Jek realized something: One of their most important and expensive resources, data scientists, were spending far too much time cleaning data. That wasn’t part of their remit and resulted in a waste of time and money.
As a COO, this a major concern for any company undertaking a machine learning initiative. Data scientists are hard to come by and their salaries have been on the rise for the last few years. Yet according to some reports data scientists spend upto 80% of their time just preparing data—not creating models.
Watch how operational teams at Go-Jek combined the right Google tools and processes to improve the productivity of their data scientists.

May is Asian American Pacific Islander Heritage Month — a time for us to come together to celebrate and remember the important people and history of Asian and Pacific Island heritage. This feature highlights founder Georgene Huang and how her startup Fairygodboss uses easy to use Google Cloud tools to grow and innovate.
Coming from a male-dominated industry like Wall Street, I never thought much about my gender. I was so focused on work that I didn’t feel like I could focus on my identity as a woman of color. That all changed when I found myself thrust into the job market while two months pregnant.
Traditionally, job-seeking sites are built by – and geared towards – men and their professional needs. There was no recruiting site that broke down what candidates who identify as women might expect from a company, let alone women of color like myself. I founded Fairygodboss to create a space where women can crowdsource information about opportunities and employers in order to make informed career decisions.
Fairygodboss
Fair•y•god•boss (noun): A person who elevates women at work.
Fairygodboss is the largest career community for women. In researching potential employers, I had many questions surrounding company culture, maternity leave, and women in leadership positions. While sites like Glassdoor provide high-level details for job seekers, I wanted more concrete examples and data than general salary information and anecdotes about work-life balance.
Fairygodboss began as a job review site geared towards women, but has expanded significantly since our initial launch. In addition to providing free resources like career connections, job listings, virtual recruiting events, community advice, and real research on how companies treat women, we also proactively help companies improve gender diversity. Fairygodboss partners with hundreds of top employers to create a 360-degree recruiting and employer branding program designed to drive female applicants to job postings by showcasing a company’s track record of women in leadership within a company, and their diversity investments.
Google Cloud + Fairygodboss: Data defined
At our core, Fairygodboss is a data-driven company, and we rely on Google Cloud to help us process, store, and analyze user-driven events occurring on the site. As a highly scalable, serverless, and cost-effective data warehousing solution, BigQuery collect millions of events each day, helping us identify where traffic is coming from (and where it goes next), and it produces actionable insights to provide better recommendations, information, and opportunities for women visiting our platform.
After seamlessly connecting our BigQuery data to Data Studio, we have been able to visualize and make sense of all the data we receive on our platform. Unlike some other data visualization tools, Data Studio allows us to analyze data in real time. With tools like BigQuery, we are now able to identify trends and gain a deep understanding for how our users interact with our site.
Google for Startups Accelerator: Women Founders
In order to provide more accurate job recommendations for our users, the Fairygodboss team wanted to build a machine learning prototype to classify our users and jobs into categories to facilitate more effective matching. So we applied for the Google for Startups Accelerator: Women Founders, a three-month digital accelerator program for high-potential Seed to Series A tech startups based in the U.S. and Canada. Along with tailored mentorship and product support from Googlers and industry experts, the Google for Startups Accelerator provided $100K in Google Cloud credits to scale our businesses. The mentorship we received from the Google Cloud technical experts as part of the Accelerator – special shout out to Peter Novig! – empowered us to integrate Cloud AutoML into our systems and ultimately curate more accurate job suggestions for our users.
Not only did the Google for Startups Accelerator program help to achieve our business goals for the year, it was also extremely beneficial to be connected with a cohort of other women founders of color. While we are all building different kinds of businesses across different industries, the guidance around fundraising, scaling teams, and coping with the struggles of being a founder rang true for all of us.
Advancing the community
It can be daunting to launch your own business – and even more so as an AAPI woman. Throughout my career, I am certain I have experienced unconscious bias around my race. Specifically, there have likely been “model minority” stereotypes about my demeanor and math abilities, assumptions that I may be mild-mannered or agreeable. While frustrating, these unfair tropes actually inspired me to see myself beyond others’ perceptions. Why be either analytical or creative, meek or brash, inspiring or agreeable? It’s the ors of life that prevent us from seeing ourselves as truly multi-dimensional individuals. I aspired to be more instead of or, and want my company to be as well.
As an inclusion-focused business, it is extremely important that Fairygodboss mindfully engage with all underrepresented groups. Diversity can be sliced in many different ways, and these intersections lead to great opportunities for change. We have a team of volunteer ‘culture wizards’ at work that provide educational resources and videos for those wanting to learn more about different cultures and identities from members of under-represented groups. We also practice what we preach at Fairygodboss by prioritizing diverse slates and diversity in our own hiring process. We aim for the talent we hire to be representative of the diverse communities we support. It is imperative to take an intentional approach to hiring diverse talent, as it falls on all employers to promote equity and inclusion—there are always ways in which we can all improve. Fairygodboss looks forward to evolving with Google Cloud in 2021 and beyond as we work together to foster inclusive teams around the world.
