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.

Millions of people annually view esports, as top players and teams compete in thrilling, fast-paced tests of reflexes, strategy, and teamwork. Fans are a diverse group, sharing a passion for action. A new, revolutionary project we’re working on with Call of Duty League just made that action a lot better.

ActivStat brings fans, players, and commentators the power of competitive statistics in real-time—stats that matter not only to the game at hand, but also for a full roster of competitors globally. Using ActivStat, live broadcasts will soon be enhanced with more depth and color-of-play while they’re happening, building excitement and adding to the overall experience.

Technically, ActivStat is an entirely new capability for esports. It’s a constantly updating catalog of statistics that is sourced, analyzed, updated, and delivered in an easy-to-consume way across global-scale computing systems, with a latency of milliseconds or seconds, rather than minutes or hours. By comparison, many of these stats today are available to fans after a day or more of processing.

Call of Duty League plans to begin rolling out ActivStat during the 2021 season. The initial rollout will include critical information like player and team standings and winning ratios across multiple aspects of virtual combat—including ultimately what these numbers mean for rankings. ActivStats are delivered both in raw statistics and via visualizations and graphics, providing commentators with fast access to the types of insights fans crave. 

For engineers at both companies, building the service has been an epic success all its own. Due to a sponsorship with Call of Duty signed last February, our dedicated game engineering team quickly innovated a new solution incorporating high-speed networking, data pipelines from multiple cloud sources, and data warehousing to create a user-friendly dashboard. Real data was flowing into commentator dashboards by April.

Esports are more complex to cover in many ways than regular sports. Instead of a well-defined physical playing field (often a simple rectangular space), multiplayer games involve complex and sprawling virtual environments that can be the size of a large campus or airport with multiple levels and hidden locations.   

Gameplay between competitors happens across many of these locations simultaneously. In addition, competitors also each choose their own configurations of equipment, known as “loadouts,” which can dramatically affect gameplay and strategy. All of this additional complexity in online gaming involves data that needs to be captured, analyzed, and communicated to the fans in insightful ways.

Two Google Cloud technology capabilities play central roles in the operations of ActivStat. BigQuery—a planet-scale data warehouse that can store and query petabytes of information in real time—is the foundation of the ActivStat platform for gathering and summarizing millisecond-level statistics. Looker, an intuitive analytic dashboard, surfaces those insights to commentators in an easy-to-use, real-time dashboard that enables the commentators to speak to compelling insights and statistics in sync with the gameplay as it is happening in the live broadcast.

While the initial release of ActivStat for this season of Call of Duty League provides compelling and powerful capabilities, it’s only the beginning of this Call of Duty League-Google Cloud co-innovation partnership. Our future vision is mapping gameplay hotspots on the field, and predicting where to place cameras with machine learning as the match evolves–enabling broadcast producers to build excitement for fans by always being in the middle of the best action. Call of Duty League and Google will also look to drive statistics and metrics directly into the broadcast feed.

The implications of the real-time statistical capabilities of ActivStat go beyond gaming and esports. Historically, gaming has been at the leading edge of what computer processing, computer graphics, wide-area networking, data analysis, and insight can do. The real-time data ingestion and output used in ActivStat could one day be useful powering live broadcasts in other types of sporting events, as well as blending live video feeds and data to support use cases in media & entertainment, healthcare, finance, manufacturing, and other verticals. We’re excited about the potential for this bold new solution and partnership between Call of Duty League and Google in esports and beyond.

At HSBC, we serve 39 million customers, in-person and online, from consumers to businesses, in 66 countries. We maintain data centers in 21 countries, with more than 94,000 servers. With an on-premises infrastructure supporting our business, we kept running into capacity challenges, which really became an innovation blocker and ultimately a business constraint.

Our teams wanted to do more with data to create better products and services, but the technology tools we had weren’t letting us grow and explore. And that data was growing continually. Just one of our data warehouses had grown 300% from 2014 to 2018.

We had a huge amount of data, but what’s the point of having all that data if we couldn’t get insights and business value from it? We wanted to serve our customers flexibly, in the ways that work best for them. 

We knew moving to cloud would let us store and process more data, but as a global bank, we were moving complex systems that needed to also be secure.

It was a team effort to create the project scope and strategy up front, and it paid off in the end. Our cloud migration now enables us to use an agile, DevOps mindset, so we can fail fast and deliver smaller workloads, with automation built in along the way.

This migration also helped us eliminate technical debt and build a data platform that lets us focus on innovation, not managing infrastructure. Along the way, we invented new technology and built processes that we can use as we continue migrating.

Planning for a cloud move
We chose cloud migration because we knew we needed cloud capabilities for our business to really reach its digital potential. We picked Google Cloud, specifically BigQuery, because it’s super fast over small and large datasets, and because we could use both a SQL interface and Connected Sheets to interact with it.

We had to move our data and its schema into the cloud—without having to manually manage every detail and miss the timelines we had set. Our data warehouse is huge, complex, and mission-critical, and didn’t easily lend itself to fit into existing reference architectures. We needed to plan ahead and automate to make sure the migration was efficient, and to ensure we could simplify data and processes along the way.

The first legacy data warehouse we migrated had been built over a period of 15 years, with 30 years worth of data comprising millions of transactions and 180 TB of data.

It ran 6,500 extract, transform, load (ETL) jobs and more than 2,500 reports, getting data from about 100 sources. Cloud migration choices usually involves either re-engineering or lift-and-shift, but we decided on a different strategy for ours: move and improve.

This allowed us to take full advantage of BigQuery’s capabilities, including its capacity and elasticity, to help solve our essential problem of capacity constraints. 

Taking the first steps to cloud
We started creating our cloud strategy through a mapping exercise, which also helped start the change management process among internal teams. We chose architecture decision records as our migration approach, basing those on technical user journeys, which we mapped out using an agile board. User journeys included things like “change data capture,” “product event handling,” or “slowly changing dimensions.” 

These are typical data warehouse topics that have to be addressed when going through a migration, and we had others more specific to the financial services industry, too.

For example, we needed to make sure the data warehouse would have a consistent, golden source of data at a specific point in time. We considered business impacts as well, so we prioritized initially moving archival and historical data to immediately take load off of the old system.

We also worked to establish metrics early on and introduce new concepts, like managing queries and quotas rather than managing hardware, so that data warehouse users would be prepared for the shift to cloud.

To simplify as we went, we examined what we currently had stored in our data warehouse to see what was used or unused. We worked with stakeholders to assess reports, and identified about 600-plus reports that weren’t being used that we could deprecate. We also examined how we could simplify our ETL jobs to remove the technical debt added by previous migrations, giving our production support teams a bit more sleep at night. 

We used a three-step migration strategy for our data: first, migrating schema to BigQuery; second, migrating the reporting load to BigQuery, adding metadata tagging and performing the reconciliation process; and third, moving historical data by converting all the SQL script into data into BigQuery-compliant scripts. 

Creating new tools for migration automation
In keeping with our automation mantra, we invented multiple accelerators to speed up migration. We developed these to meet the timelines we’d set, and to eliminate human error. 

The schema parser and data reconciliation tool helped us migrate our data layer onto BigQuery. SQL parser helped migrate the data access layer onto Google Cloud Platform (GCP) without having to individually migrate 3,500 SQL instances that don’t have data lineage or documentation. This helped us to prioritize workloads.

And the data lineage tool identified components across layers to find dependencies. This was essential for finding and eliminating integration issues during the planning stage, and for identifying application owners during the migration. Finally, the data reconciliation tool reconciles any discrepancies between the data source and the cloud data target. 

Building a cloud future
We used this first migration in our UK data center as a template, so we now have a tailored process and custom tools that we’re confident using going forward.

Our careful approach has paid off for our teams and our customers. We’re enjoying better development and testing procedures. We’ve created an onboarding path for applications, we have a single source of truth in our data warehouse, and we use authorized views for secure data access. The flexibility and scalable capacity of BigQuery means that users can explore data without constraints and our customers get the information they need, faster.
