Education data can inform strategy, enhance both teaching and learning, and help us better understand customer needs. But that data is only as useful as an organization’s ability to access, analyze, and act upon it. Education Technology (EdTech) companies with a strong data warehouse management policy can help to make the most of educational data at all levels.

Creating a data team

When an EdTech doesn’t have a dedicated data team, databases will likely be poorly maintained and data can be hard to find, it can lack critical security, or fail to meet a customer’s specific requirements. A dedicated data team can prevent this and better support an organization’s data needs.  There’s a correlation between the maturity of a data team and the success of an organization’s data utilization. When considering the three primary components of team, outlook, and results, we can better understand an organization’s maturity. By using this matrix from Looker’s Analytical Maturity Playbook, you can assess the maturity of your organization’s data team. Most would agree, the goal is for your operation to move from data chaos to data-driven. But, how can you do that? Think about your data this way: the intelligence you gain from your data is not only an asset…it’s a product. When your data team views your business intelligence as a product—one that’s just as important as the services you offer—they can set the stage for creating a successful data-driven company. Mature data organizations:

• Report functionality regularly
• Constantly assess potential improvements to existing systems
• Manage content rollout to internal employees

Redivis: Making data accessible, connected & secure

Redivis is a platform that connects academic researchers with data and the tools to understand education intelligence. Their customers, who are researchers, expressed how difficult it is to find new datasets for their studies. Once they found a dataset, they often had to access and work with it before they could tell if the information would be useful for their studies. Redivis Data administrators were also concerned about data security. Redivis built their platform on top of Google Cloud’s security infrastructure, making it a highly scalable data processing environment. 

Redivis developed a transparent, tiered access system for datasets that allows researchers to request separate access to a dataset’s documentation to determine whether they can use the dataset. Detailed audit logs (supported by Google Cloud Logging) and robust application-level security controls tighten data access. To offer more insights for their researchers, they securely connected their private datasets with public datasets hosted in BigQuery allowing researchers to run queries on billions of records in seconds, not hours.

With a data team in place, it’s time to visualize where to store and organize your data. Data is an asset. You want to invest in collecting, operationalizing, and storing it properly. “Inadequate data aggregation, harmonization, and processing impedes teams from making the right data-driven decisions and pivoting when needed,” according to Jesus Trujillo Gomez, a strategic business executive at Google Cloud. You can determine how mature your warehouse is by using this matrix to help you identify where your organization falls on the spectrum (least mature on the left, most mature on the right). A company’s data warehouse can be assessed in four areas: Technology, Pipeline, Quality, and Performance. Here are some suggested steps to bring your EdTech company one step closer to a data powerhouse. 

Classcraft: Using a data-driven approach to make learning fun

Launched in 2014, learning company Classcraft is reimagining the classroom, creating better learning environments with gamification. To support their mission, their team has created a complete data platform that uses data analytics to find new ways to engage students in the classroom. Classcraft became a Google for Education Build Partner to keep up with rising demand. They expanded their footprint to reach 6 million students and educators in 165 countries. 

They also migrated to Google Cloud, building on several integrations with Google Workspace for Education, Google Classroom, and Chrome for Education, allowing them to support customers ranging from individual teachers to entire school districts.  Classcraft migrated its database and analytics infrastructure to BigQuery and Cloud Storage. “We capture about 10 million new data points every month related to school culture and student performance,” says Chief Technology Officer and VP of Product Stéphane Guillemette. “With BigQuery and other Google Cloud tools, we can quickly deliver valuable insights to educators.”

In general, the MySQL functionality provided by a Google Cloud’s SQL Database (Cloud SQL) instance is the same as the functionality provided by a locally-hosted MySQL instance.

However, there are a few differences between a standard MySQL instance and a Cloud SQL for MySQL instance.

Unsupported Features

• User defined functions
• InnoDB memcached plugin
• Federated Engine
• The SUPER privilege

Unsupported Statements

Sending any of the following types of SQL statements will generate an error with the message “Error 1290: The MySQL server is running with the google option so it cannot execute this statement”:

• LOAD DATA INFILE
• Note that LOAD DATA LOCALINFILE is supported.
• SELECT … INTO OUTFILE
• SELECT … INTO DUMPFILE
• INSTALL PLUGIN …
• UNINSTALL PLUGIN
• CREATE FUNCTION … SONAME …

Unsupported Statements for Second Generation Instances

The following statements are not supported because Second Generation instances use GTID replication:

• CREATE TABLE … SELECT statements
• CREATE TEMPORARY TABLE statements inside transactions
• Transactions or statements that update both transactional and nontransactional tables

For more information, see the MySQL documentation.

Unsupported Functions

• LOAD_FILE()

Unsupported Client Program Features

• mysqlimport without using the –local option. This is because of the LOAD DATA INFILE restriction. If you need to load data remotely, use the Cloud SQL import function.

• mysqldump using the –tab option or options that are used with –tab. This is because the FILE privilege is not granted for instance users. All other mysqldump options are supported.

• If you want to import databases with binary data into your Cloud SQL for MySQL instance, you must use the –hex-blob option with mysqldump.

• Although hex-blob is not a required flag when you are using a local MySQL server instance and the mysql client, it is required if you want to import any databases with binary data into your Cloud SQL instance. For more information about importing data, see Importing Data.

• Not all MySQL options and parameters are enabled for editing as Cloud SQL flags.

• To request the addition of a configurable Cloud SQL flag, use the Cloud SQL Discussion group.

• For Second Generation instances, InnoDB is the only supported storage engine. For help with converting tables from MyISAM to InnoDB, see the MySQL documentation.

• You cannot import or export triggers, functions, stored procedures, or views into Cloud SQL. However, you can create and use these elements on a Cloud SQL instance.

Notable MySQL Options

Cloud SQL runs MySQL with a specific set of options. If an option might impact how your applications work, we note it here for your information.

For a business to succeed in the long term, it needs to learn not just to adapt to inevitable change, but to harness it. South Africa-based PPS has been an insurance company since 1941 and today is the biggest mutual insurance provider in the country.

As a mutual company, PPS is owned by more than 200,000 members, making them shareholders. In recent years, PPS and other companies like it have been affected by a number of external factors.

“For one thing, technology platforms have brought in a new gig economy that has all kinds of implications for insurance,” says Avsharn Bachoo, CTO at PPS. “What we’ve been seeing is basically a disruption of the South African insurance industry. We chose to see that as an opportunity.”

“Our servers were at the end of their life cycle and we had to decide whether to refresh them or switch completely. To embrace the world of AI and machine learning effectively, we knew we needed a cloud-based infrastructure. We’ve found the answer in Google Cloud Platform.”

—Avsharn Bachoo, CTO, PPS

In early 2018, faced with an uncertain economic environment that was squeezing growth and profitability, PPS decided to transform itself from a traditional broker-based business into a digital insurance provider. A key pillar of this new strategy was to overhaul the company’s technology infrastructure. To turn the strategy into reality, Avsharn and his team chose Google Cloud Platform (GCP).

“Our servers were at the end of their life cycle and we had to decide whether to refresh them or switch completely,” says Avsharn. “To embrace the world of AI and machine learning (ML) effectively, we knew we needed a cloud-based infrastructure. We’ve found the answer in Google Cloud Platform.”

Power, speed, flexibility with Google Cloud Platform

Previously, PPS maintained an on-premises IT infrastructure, which worked for its traditional business but was unsuited for its new way of working. In early 2018, the company started working on new products for its members but this required large amounts of compute power that proved prohibitively expensive with on-premises servers. Even existing products were starting to require more than the infrastructure could deliver. Aging equipment meant that it’s testing and quality assurance environments bore little resemblance to the actual production environment.

“We had no pre-production environments at all,” says Avsharn, resulting in more work for developers after products had been released. Meanwhile, the capital required to buy and configure more servers for new projects meant fewer resources available for innovation, and left the company less able to react to changes in the market. PPS knew it had to find a cloud-based alternative.

Shortly after devising a new digital strategy, PPS engineers attended a training session on cloud infrastructure given by leading South African Google Cloud Partner Siatik. Impressed with the presentation, PPS engaged Siatik to help run a proof of concept for a cloud-based infrastructure, running on GCP. With on-site engineers and constant communication, Siatik formed a very close working relationship with PPS. “The team at Siatik was exemplary,” recalls Avsharn. “They were well-organized, with cutting-edge technical acumen and very creative solutions to our problems. They were real game-changers.”

“We wanted the platform to retrain its models in response to new data and improve its recommendations with more information. Normally this would be a manual process but Google Cloud ML Engine lets the models do this automatically.”

—Kimoon Kim, Lead Solution Architect and Data Engineer, Siatik

The proof of concept was successful, with GCP outperforming the existing infrastructure in terms of how it handled compute demands, databases, and storage.

“It’s the speed of GCP that really impresses us,” says Avsharn. PPS saw that GCP wasn’t just an opportunity to migrate its existing infrastructure to the cloud. With Siatik’s help, it redesigned its monolithic core architecture to one based around microservices using Google Kubernetes Engine (GKE). For data processing and storage, Cloud Dataflow and Cloud Datastore proved invaluable, while Stackdriver helped the IT team stay on top of logging and monitoring the system.

“Google Cloud makes migrations very easy,” says Brett St. Clair, CEO at Siatik. “It takes care of all the hard work with configurations and replications, so when we switch the machines on, everything is ready and working.”

The ease with which PPS migrated to GCP means that it can now tackle strategic goals much more quickly than before. The most ambitious of these is an AI-powered product recommendation platform. Information is collected from customers who opt in at a defined point in their journey, this database is queried using BigQuery, and the information is fed into the platform. The AI model then calculates the most appropriate products for each member, according to their personal history.

“Most of the product recommendation engines out there are based on clustering, where you’re offered products based on your peer groups,” explains Avsharn. “For the first time, we can make recommendations to members based on their individual preferences and historical behavior. That’s really powerful for us.”

Siatik helped PPS use TensorFlow and Cloud Machine Learning Engine to build the AI platform. For the engineers, these easy-to-use tools helped speed up the process considerably, allowing them to host the models locally without any fuss. Previously, it took one to three months to manually build the model and match an offer to a customer. With the AI platform, a match takes just a few minutes. Cloud ML Engine, in particular, helped the platform adapt to new information on the fly and easily make adjustments to its hyperparameters, that is, preset variables which define the model-training process.

“We wanted the platform to retrain its models in response to new data and improve its recommendations with more information,” says Kimoon Kim, Lead Solution Architect and Data Engineer at Siatik. “Normally this would be a manual process but Google Cloud ML Engine lets the models do this automatically.”

“Google Cloud helped us cancel out a lot of the noise around machine learning and AI. We don’t have to build new complicated algorithms or hire huge teams of data scientists to benefit. We just bring our data and use the right tools to focus on what’s really important.”

—Avsharn Bachoo, CTO, PPS

Harnessing artificial intelligence for real-world results

PPS deployed its new AI recommendation platform in December, 2018. Just a couple of months later, its impact was clear. “In around eight weeks, we saw a 5 percent growth in sales,” says Avsharn. “It’s been a direct result of building our recommendation platform with Google Cloud. We can offer the right products to the right members.”

For developers and engineers at PPS, working with Google Cloud gives them access to high performance technology and automation options with GKE. As a result, the infrastructure runs 70 percent faster than before with fewer cores and less memory. Developers can also work in mature testing environments, and for the first time, are able to build pre-production environments, leading to better quality products. More strategically, moving to a serverless, cloud-based infrastructure has helped PPS take control of its budget, moving away from intermittent, large capital spends to more manageable, project-to-project flows of operational expenditure. The company expects to see savings of around 50 percent, or $695,000.

“We have a lot more flexibility with our resources thanks to Google Cloud,” says Avsharn. “When we have a new idea, we don’t have to outlay new capital such as servers before we can even start working on it. We just spin up instances when we want and spin them back down when we’re done.”

With the AI platform deployed and working well, PPS is already looking at ways to improve it, including real-time updates and further automation. Soon, the company will integrate the platform with more sales campaigns for more effective targeting to boost sales even further. Meanwhile, it’s also experimenting with machine learning to spot patterns in data at scale for fraud analytics and risk assessment.

For PPS, working with Google Cloud has helped it transform quickly and effectively from disrupted to disruptor. The company is now looking to gain the same transformative effects by implementing G Suite for increased productivity and collaboration.

“Google Cloud helped us cancel out a lot of the noise around machine learning and AI,” says Avsharn. “We don’t have to build new complicated algorithms or hire huge teams of data scientists to benefit. We just bring our data and use the right tools to focus on what’s really important.”

Research shows that over 90% of large organizations already deploy multicloud architectures, and their data is distributed across several public cloud providers. Additionally, data is also increasingly split across various storage systems such as warehouses, operational and relational databases, object stores, etc. With the proliferation of new applications, data is serving many more use cases such as data sciences, business intelligence, analytics, streaming and the list goes on. With these data trends, customers are increasingly gravitating towards an open multicloud data lake. However, multicloud data lakes present several challenges such as data silos, data duplication, fragmented governance, complexity of tools, and increased costs.

With Google’s data cloud technologies, customers can leverage the unique combination of distributed cloud services. They can create an agile cross-cloud semantic business layer with Looker and manage data lakes and data warehouses across cloud environments at scale with BigQuery and capabilities like BigLake and BigQuery Omni.

BigLake is a storage engine that unifies data warehouses and lake houses by standardizing across different storage formats including BigQuery managed table and open file formats such as Parquet and Apache Iceberg on object storage. BigQuery Omni provides the compute engine that runs locally to the storage on AWS or Azure, which customers can use to query data in AWS or Azure seamlessly. This provides several key benefits such as:

1. A single pane of glass to query your multicloud data lakes (across Google Cloud Platform, Amazon Web Services, and Microsoft Azure)
2. Cross-cloud analytics by combining data across different platforms with little to no egress costs
3. Unified governance and secure management of your data wherever it resides

In this blog, we will share cross-cloud analytics use cases customers are solving with Google’s Data Cloud and the benefits they are realizing.

Unified marketing analytics for 360-degree insights

Organizations want to perform marketing analytics – ads optimization, inventory management, churn prediction, buyer propensity trends and many more such analytics. To do this before BigQuery Omni, customers had to use data from several different sources such as Google Analytics, public datasets and other proprietary information stored across cloud environments. This requires moving large amounts of data, managing duplicate copies and incremental costs to perform any cross-cloud analytics and derive actionable insights. With BigQuery Omni, organizations are able to greatly simplify this workflow. Using the familiar BigQuery interface, users can access data residing in AWS or Azure, discover and select just the relevant data that needs to be combined for further analysis. This subset of data can be moved to Google Cloud using Omni’s new Cross-Cloud Transfer capabilities. Customers can combine this data with other Google Cloud datasets and these consolidated tables can be made available to key business stakeholders through advanced analytics tools such as Looker and Looker Studio. Customers are also able to tie in this data now with world class AI models via Vertex AI.

As an illustrative example, consider a retailer who has sales & inventory, user and search data spread across multiple data silos. Using BigQuery Omni they can seamlessly bring these datasets together and power several marketing analytics scenarios like customer segmentation, campaign management and demand forecasting etc.

“Interested in performing cross-cloud analytics, we tested BigQuery Omni and really liked the SQL support to easily get data from AWS S3. We have seen great potential and value in BigQuery Omni for adopting a multi-cloud data strategy.” — Florian Valeye, Staff Data Engineer, Back Market, a leading online marketplace for renewed technology based out of France

Data platform with consistent and unified cross-cloud governance

Another pattern is customers looking to analyze operational, transactional and business data across data silos in different clouds through a unified data platform. These data silos are a result of various factors such as merger and acquisitions, standardization of analytical tools, leveraging best of breed solutions in different clouds and diversification of data footprint across clouds. In addition to a single pane of glass for data access across silos, customers deeply desire consistent and uniform governance of their data across clouds.

“Achieve is looking to deliver a consistent analytics experience to all our customers and stakeholders. With our financial and credit report data distributed across clouds, accessing and getting insights holistically is difficult. Through our exploration with Omni, we are able to access datasets in different clouds using a single familiar BigQuery interface; we see its promise as one of the primary tools in our multi-cloud platform.” — James Simonson, Senior Data Engineer, Achieve

With BigLake and BigQuery Omni abstracting the storage and compute layers respectively, organizations can access and query their data in Google Cloud irrespective of where it resides. They can also set fine-grained row level and column access policies in BigQuery and consistently govern it across clouds. These building blocks enable data engineering teams to build a unified and governed data platform for their data users without having to deal with the complexity of building and managing complex data pipelines. Furthermore, with BigQuery Omni’s integration with Dataplex and Data Catalog, you can discover, search your data across clouds and enrich your data by adding relevant business context with business glossary and rich text.

“Several SADA customers use GCP to build and manage their data analytics platform. During many explorations and proofs of concepts, our customers have seen the great potential and value in BigQuery Omni. Enabling seamless cross-cloud data analytics has allowed them to realize the value of their data quicker while lowering the barrier to entry for BigQuery adoption in a low-risk fashion.” — Brian Suk, Associate Chief Technology Officer, SADA, one of the strategic partners of Google Cloud.

Simplified data sharing between data providers and their customers

A third emerging pattern in cross cloud analytics is data sharing. Several services have the business need to share information such as inventory data, subscriber data to their customers or users who in turn analyze or aggregate the data with their proprietary data and oftentimes share the results back with the service provider. In several cases, the two parties are on different cloud environments, requiring them to move data back and forth.

Consider a company operating in the customer data platform (CDP) space. CDPs were designed to help activate customer data, and a critical first step of that was unifying and managing that customer data. To enable this, many CDP vendors built their solution choosing one of the available cloud infrastructure technologies and copied data from the client’s systems.“Copying data from client applications and infrastructure has always been a requirement to deploy a CDP, but it doesn’t have to be anymore” — Justin DeBrabant, Senior Vice President of Product, ActionIQ.

While a small percentage of customers are fine with moving data across cloud environments, the majority are hesitant to onboard new services and would rather prefer providing governed access to their data sets.

“A new architectural pattern is emerging, allowing organizations to keep their data at one location and make it accessible, with the proper guardrails, to applications used by the rest of the organization’s stack” adds Justin at ActionIQ.

With BigQuery Omni, services in Google Cloud Platform can more easily access and share data with their customers and users in other cloud environments with limited data movement. One of UK’s largest statistics providers has explored Omni for their data sharing needs.

“We tested BigQuery Omni and really like the ability to get data from AWS directly into BQ. We’re excited about managing data sharing with different organizations without onboarding new clouds” – Simon Sandford-Taylor, Chief Information and Digital Officer, UK’s Office for National Statistics

With BigQuery Omni, customers are able to:

• Access and query data across clouds through a single user interface
• Reduce the need for data engineering before analyzing data
• Lower operational overhead and risks by deploying an application that runs across multiple clouds which leverages the same, consistent security controls
• Accelerate access to insights by significantly reducing the time for data processing and analysis
• Create consistent and predictable budgeting across multiple cloud footprints
• Enable long term agility and maximize the benefits every cloud investment

Over the last year, we’ve seen great momentum in customer adoption and added significant innovations to BigQuery Omni including improved performance and scalability for querying your data in AWS S3 or Azure Blob Storage, Iceberg support for Omni, Larger query result set size up to 20GB and Cross-cloud transfer that helps customers easily, securely, and cost effectively move just enough data across cloud environments for advanced analytics.

BigQuery Omni has launched several features to support unified governance of your data across multiple clouds – you can get fine-grained access to your multi-cloud data with row level and column level security. Building on this, we are excited to announce that BigQuery Omni now supports data masking. We’ve also made it easy for customers to try and see the benefits of BigQuery Omni through the limited time free trial available until March 30, 2023.

BigQuery Omni running on other public clouds outside of Google Cloud is available in AWS US East1 (N.Virginia) and Azure US East2 (US East) regions. We are also excited to share that we will be bringing BigQuery Omni to more regions in the future, starting with Asia Pacific (AWS Korea) coming soon.
