Organizations rely on data warehouses to aggregate data from disparate sources, process it, and make it available for data analysis in support of strategic decision-making. BigQuery is the Google Cloud enterprise data warehouse designed to help organizations to run large scale analytics with ease and quickly unlock actionable insights. You can ingest data into BigQuery either through batch uploading or by streaming data directly to unlock real-time insights. As a fully-managed data warehouse, BigQuery takes care of the infrastructure so you can focus on analyzing your data up to petabyte-scale. BigQuery supports SQL (Structured Query Language), which you’re likely already familiar with if you’ve worked with ANSI-compliant relational databases. 

BigQuery unique features

BI Engine – BigQuery BI Engine is a fast, in-memory analysis service that provides subsecond query response times with high concurrency. BI Engine integrates with Google Data Studio and Looker for visualizing query results and enables integration with other popular business intelligence (BI) tools. 

BigQuery ML: BigQuery ML is unlocking machine learning for millions of data analysts. It  enables data analysts and data scientists to build and operationalize machine learning models directly within BigQuery, using simple SQL.

BigQuery Omni – BigQuery Omni is a flexible, multi-cloud analytics solution powered by Anthos that lets you cost-effectively access and securely analyze data across Google Cloud, Amazon Web Services (AWS), and Azure, without leaving the BigQuery user interface (UI). Using standard SQL and familiar BigQuery APIs, you can break down data silos and gain critical business insights from a single pane of glass. 

Data QnA: Data QnA enables self-service analytics for business users on BigQuery data as well as federated data from Cloud Storage, Bigtable, Cloud SQL, or Google Drive. It uses Dialogflow and enables users to formulate free-form text analytical questions, with auto-suggested entities while users type a question.

Connected Sheets -The native integration between Sheets and BigQuery makes it possible for all business stakeholders, who are already quite familiar with spreadsheet tools, to get their own up-to-date insights at any time.

Geospatial data – BigQuery offers accurate and scalable geospatial analysis with geography data types. It supports core GIS functions – measurements, transforms, constructors, and more – using standard SQL.

How does it work?

Here’s how it works: You ingest your own data into BigQuery or use data from the public datasets. Storage and compute are decoupled and can scale independently on demand. This offers immense flexibility and cost control for your business as you don’t need to keep expensive compute resources up and running all the time. As a result, BigQuery is much more cost-effective than traditional node-based cloud data warehouse solutions or on-premises systems. BigQuery also provides automatic backup and restore of your data. 

You can ingest data into BigQuery in batches or stream real-time data from web, IoT, or mobile devices via Pub/Sub. You can also use Data Transfer Service to ingest data from other clouds, on-premises systems or third-party services. BigQuery also supports ODBC and JDBC drivers to connect with existing tools and infrastructure. 

Interacting with BigQuery to load data, run queries, or create ML models can be done in three different ways. You can use the UI in the Cloud Console, the BigQuery command-line tool, or the API via client libraries available in several languages.

When it comes time to visualize your data, BigQuery integrates with Looker as well as several other business intelligence tools across the Google partner ecosystem.

What about security?

BigQuery offers built-in data protection at scale. It provides security and governance tools to efficiently govern data and democratize insights within your organization. 

• Within BigQuery, users can assign dataset-level and project-level permissions to help govern data access. Secure data sharing ensures you can collaborate and operate your business with trust.
• Data is automatically encrypted both while in transit and at rest, ensuring that your data is protected from intrusions, theft, and attacks. 
• Cloud DLP helps you discover and classify sensitive data assets.
• Cloud IAM provides access control and visibility into security policies.
• Data Catalog helps you discover and manage data. 

How much does it cost?

The BigQuery sandbox lets you explore BigQuery capabilities at no cost and confirm that BigQuery fits your needs. With BigQuery you get predictable price-performance: you pay for storing and querying data, and for streaming inserts. Loading and exporting data are free of charge. Storage costs are based on the amount of data stored, and have two rates based on how often the data is changing. Query costs can be either:

• On-demand – you are charged per query by the amount of data processed
• Flat-rate – if you prefer to purchase dedicated resources 

You can start with the pay-as-you-go, on-demand option and later move to flat-rate if that better suits your usage. Or, start with flat-rate, get a better understanding of your usage and move to the pay-as-you-go models for additional workloads.

Dr. Elliot Smith cannot be accused of lacking ambition. A high achiever with a Ph.D. in Electrical Engineering and a specialist in magnetic resonance imaging (MRI) systems, Smith aims to deliver top quality healthcare to anyone in the world — regardless of their location or wealth.

Dr. Smith has already made strides on this journey with his Brisbane, Queensland-headquartered business, Maxwell MRI. “I saw there was a big gap in the market around automating the diagnosis of health conditions,” he says. “Existing processes were typically manual and involved a lot of people.”

Artificial intelligence (AI) and machine learning can remove a key obstacle to scaling out medicine and improve the efficiency and accuracy of diagnosing conditions, the healthcare entrepreneur believes.

“Our grand vision is to build an AI doctor that anyone can receive affordable support from and connect to in order to obtain results,” explains Dr. Smith.

Maxwell MRI presently enables clinicians to submit anonymised MRI scans to a machine learning enabled AI platform to help diagnose prostate cancer. The service is sold to clinicians who can then charge a per-session fee to clients. As well as obtaining results for individual cases, the MRI scans and associated information is used to ‘train’ the platform to deliver accurate diagnoses faster and in a more affordable way than existing systems do.

Dr. Smith and his team started by running a number of functions and processes on a single server with graphics processing units (GPUs) and sizable hard disk capacity. However, this infrastructure could not scale to support the planned growth of the business. Each case Maxwell MRI processes involves about 200MB of data in MRI scans alone. Once supplementary data, blood test result, pathology results and genetic information is included, this load can reach more than 1GB of data per patient.

The business aimed to process 150,000 cases by the end of 2018. This required a service that could deliver massive scale in data storage and compute, and could easily be accessed from any location. “We wanted to move from three GPUs to 30 GPUs without having to buy more servers or other associated equipment, so the cloud was the natural next step,” says Dr. Smith.

Maxwell MRI evaluated Google Cloud Platform (GCP) and determined that the managed services component of GCP would remove the burden of infrastructure deployment and administration. In addition, Google Cloud Machine Learning Engine would enable the business to scale to as many GPUs as needed to meet demand.

Maxwell MRI started with some small experiments to determine that GCP met all its requirements and completed its migration to the platform in February 2017. “We really started to scale up the data we had and consequently our computing requirements at that time,” Dr. Smith says.

The Maxwell MRI platform features an upload service that enables clinicians to upload imaging and associated data. This service triggers several different upload pipelines that clean and standardise data. They then write imaging data to Google Cloud Storage, and more structured data to a combination of Google Cloud Datastore and Google Cloud Spanner.

The platform then converts the information into records that can be used to ‘train’ new machine learning configurations or run evaluations through existing machine learning pipelines.

“The tasks we perform including segmenting various anatomical regions for analysis and sending those results back into Google Cloud Storage,” says Dr. Smith. “This then commences that repeated process of running Google Cloud Dataflow pipelines and machine learning algorithms, and presenting those outcomes back to the clinicians.”

Existing Literature Validated

The data processed and analysed to date has, Dr Smith says, enabled Maxwell MRI to help validate existing literature that indicates clinicians lack confidence in existing early-stage testing procedures for prostate cancer. This prompts them to move quickly to the biopsy stage to assure themselves their diagnosis is valid. “New technologies have a lot of potential to rectify this situation and guide treatment to be more accurate, specific and cost-effective,” he says.

Results Delivered in 10-15 Minutes

More specifically, using GCP has enabled Maxwell MRI to guarantee to clinicians that results will be delivered within minutes. “Clinicians are used to getting results back in two days to a week,” says Dr. Smith. “We’re saying that with our platform running on GCP we’ll deliver you results in 10 to 15 minutes, regardless of the number of patients coming in.”

Running on GCP has enabled the business to accelerate its development cycles, test new ideas easily on a subset of data, test in parallel and deliver new services considerably faster than in another environment. In addition, the flexible GCP charging model aligned with the ability to scale compute capabilities quickly and easily has enabled the fledgling business to control its costs.

Google technologies are poised to play an integral role in the business’s future. “With Google available, it doesn’t make sense for us to use our own infrastructure,” Dr. Smith says. “Our expertise in AI, machine learning and clinical engagement complements cloud platform specialties of infrastructure, managed services and ease of use. We see a bright future ahead in helping to transform healthcare globally.”

With Google Cloud, AirAsia is now a “data first” business that can capture, analyze, and report on rising volumes of data to address complex problems and increase revenue streams. The airline is also using AI-powered chatbots to streamline internal operations and provide a faster, more efficient service.

Become a digital airline powered by data and machine learning

AirAsia’s vision is simple: allow everyone to fly. Founded in 2001, the airline and sister company AirAsia X have grown to service 150+ destinations in 25 markets, using 274 aircraft to operate 11,000+ weekly flights from 23 hubs across the region. While the airline is known as a provider of low-cost airfares to locations across Asia, this is only one part of its value proposition. AirAsia also aims to deliver innovative, personalized products and services that meet the needs of each of its passengers.

Technology is key to AirAsia’s success and, with strong support from Group Chief Executive Officer Tony Fernandes, in 2016 the airline began a five-year program to become a data-first business and a digital airline.

“We wanted to better ensure we were using data correctly to become more agile, efficient, and customer oriented,” says Lye Kong Wei, Chief of Data Science, Group Head at AirAsia.

AirAsia needed technologies and services that could capture, process, analyze, and report on data, while delivering value for money and meeting its speed and availability requirements. The airline also wanted to minimize infrastructure management and system administration demands on its technology team.

Google Cloud the best fit

AirAsia realized only a cloud service could meet its needs and began evaluating the market. The airline then conducted a proof of concept and found Google Cloud was the best fit for its business. It was already familiar with Google Cloud, having deployed Google Workspace collaboration and productivity applications to its workforce in all countries except China. According to Kong Wei, products such as Forms, Docs, Sheets, and Gmail delivered a considerable improvement in collaboration between various departments, as well as streamlining and automating a range of processes.

The business was particularly excited by the potential of the BigQuery analytics data warehouse to power its digital transformation. “We knew data was a big part of making decisions in the future,” says Kong Wei. “So we needed a platform that could scale to meet our growing appetite for it. Google Cloud—in particular BigQuery—was ideal for this task.”

The AirAsia technology team was impressed by the ease and flexibility with which it could extract, transform, and load customer data from its systems, websites, and mobile applications into BigQuery for analysis. Data, reports, and dashboards were delivered and visualized through Looker Studio.

BigQuery also scaled seamlessly to support data growth and, as a managed service, required minimal administration from the airline’s technology team. “In addition, with BigQuery, we could process queries and requests much faster than previously and tackle more complex problems,” says Kong Wei. “As a result, we could be more innovative about realizing opportunities,” he adds, citing the benefits of being able to view and understand historical measures of booking curves—a measure of how long it took customers to book before a flight. This improves the airline’s ability to manage revenues.

A broad ecosystem

BigQuery and Looker Studio are just two components of a broad ecosystem—powered largely by Google Cloud services—deployed by AirAsia. Pub/Sub provides a scalable message queue that enables AirAsia developers to integrate systems hosted on Google Cloud or externally. Apache Airflow enables the business to create, schedule, and monitor workflows, while Cloud Composer manages the dependencies of PHP and related libraries. App Engine allows AirAsia personnel to develop and host web applications. “Thanks to App Engine, we’ve easily been able to create new applications, services, and APIs powered by the data we have been collecting,” says Kong Wei.

AirAsia is also running the middleware for its APIs in a managed Google Kubernetes Engine environment for increased scalability, resource optimization, and reliability, while Cloud Storage provides storage for data from a range of systems and sources. Dataflow enables the business to transform and process data in stream and batch modes from its website search page as customers look for flights.

Faster deployment and testing

The stability of Google Cloud service means AirAsia has a reliable base from which to launch new products and features. “If we have consistent reliability from our core systems—and Google Cloud incorporates monitoring tools such Cloud Monitoring that enable us to identify issues quickly—developers and product engineers can focus on turning ideas into reality,” says Kong Wei. “With a minimal number of people involved, we can very quickly transform an idea or thought process into a deliverable. Prior to Google Cloud, bringing those ideas to fruition would have been impossible.”

Robust security

AirAsia is also relying on Security Health Analytics, a product that integrates with Security Command Center, to identify misconfigurations and compliance violations in its Google Cloud resources and take action. Security Health Analytics ensures the airline’s budgets go to keeping customers’ travel costs low rather than recovering from security breaches.

The product enables AirAsia to check that resources are configured properly and are compliant with CIS benchmarks as its critical workloads run in Google Kubernetes Engine and App Engine.

“Being able to go to the new Security Health Analytics dashboard eliminates the guesswork of what we have running and if it is secure,” says Muhammad Faeez Bin Azmi, Information Security and Automation Solution Architect. “Now anyone on our team, even non-security professionals, can go to this dashboard and see a list of the misconfigured assets and compliance violations across all of our Google Cloud resources. We can also see the severity of misconfigurations, which helps us prioritize our response.”

“Security Health Analytics has really helped us reduce the amount of time we spend trying to figure out what’s wrong with our resources. It’s allowed us to use our time more effectively to identify and resolve more security issues than we could before.”

A new identity solution

AirAsia had also used a legacy on-premises directory for many years. However, as the company grew and expanded to new markets and regions, it had to manage multiple servers across a number of on-premises data centers and the public cloud, which proved costly and time-consuming.

Its Allstars—the airline’s name for its employees—needed to easily access a number of legacy on-premises apps in addition to a growing number of SaaS apps. As a business, it also needed a more seamless integration between its HR system of record and its identity solution for user provisioning and life cycle management. Solving these challenges with its existing on-premises directory was simply not feasible.

AirAsia brought up its identity concerns with the Google Cloud team, and after a number of conversations, decided to deploy Cloud Identity, Google’s cloud-based Identity and Access Management solution, to help address the identity challenges it was facing.

The airline chose Cloud Identity for a number of reasons—first, it was eager to move to the cloud as quickly as possible. Moving identity management to the cloud was a key enabler of this and the airline’s broader digital transformation. Managing identities from the cloud also enabled the airline to have a single identity and set of credentials for each employee, which they could use to access all the applications they need to be productive, both in the cloud and on-premises.

In addition, deploying Cloud Identity was a key step towards enabling the zero trust security model, which the airline felt was the best approach to strengthen its security posture and fight modern threats. Cloud Identity also integrated seamlessly with its existing technologies, which include not only Google Cloud products like Google Workspace and Chrome OS but also third-party tools like Citrix, Papercut, and others.

And finally, Cloud Identity offered significant cost and resource savings. With Cloud Identity in place, AirAsia’s IT department could spend less time worrying about managing multiple on-premises directory servers and and could instead focus on delivering value to Allstar employees.

Machine learning employed to increase ancillary revenue

In March 2018, AirAsia established the groundwork to use machine learning to optimize pricing for a range of services and began by using AI Platform to sort and predict demand for ancillary services such as baggage, seats, and meals. “By using AI Platform, we can sort based on data about history to predict the future,” says Kong Wei.

Dialogflow in wide use

With Google Cloud well established within the business, AirAsia is using Dialogflow, a voice and conversational interface development suite (and one of the core components of Contact Center AI) that enables businesses to create engaging AI powered voice- and text-based interfaces such as chatbots and voice apps—to streamline operations and reduce costs

“Tony Fernandes, our Group Chief Executive Officer, motivated us to create a range of metrics that would enable us to respond more quickly and efficiently to customers,” says Yuashini Vellasamy, Product Manager at AirAsia.

This resulted in the initial deployment of Dialogflow in AirAsia’s operational areas, from crew scheduling to internal business tasks.

With Dialogflow, AirAsia is able to provide pilots, crew, catering, and other teams with flight times, capacity and any other relevant information about their assignments. Another bot accepts medical certificates and updates from pilots and crew members unable to make rostered assignments and switches those assignments to other pilots and crews. “This improves our on-time performance and operational efficiency, as we are able to optimize the creation of crew schedules,” says Vellasamy.

AirAsia also uses Dialogflow to power a “safety bot” for airport ground staff. “We tried a lot of tools to encourage staff to advise us when they saw a safety issue—but employee usage was low,” says Vellasamy. “However, when we set up the safety bot, which asks users just four questions about an issue they have observed, we saw an increase in employee interaction, which helps ensure proper safety measures.

Beyond crew optimization and overall safety, AirAsia’s HR department in Asia uses a Dialogflow-powered bot to run a post-orientation engagement program for new employees. The bot follows up with employees about issues from parking to AirAsia’s onboarding buddy program, saving HR employees time from scheduling one-on-one meetings. Dialogflow also powered an employee satisfaction survey of 3,000 team members, resulting in a 30% increase in response rate compared to the previous year.

One of Dialogflow’s benefits is its language coverage, which the airline’s marketing team uses to target customers and prospects across a region with diverse languages and cultures. “For weekly campaigns and promotions, our sales and marketing teams simply update the campaign materials and the changes are reflected automatically in Dialogflow and consequently to users,” says Vellasamy. “This enables us to quickly scale and reach our customers globally.”

An upward trajectory

AirAsia is poised to reap further benefits from Google Cloud as its deployment matures. “On the data side, we’re more advanced, while on the application and programming side we have a long way to go,” says Kong Wei. “We’re on a trajectory upwards—we’re looking at a lot of new ideas and how to embrace and deploy them so we can further our data-first and digital airline agendas.”
