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.

Google Cloud Results

• Improves performance and reliability, enabling Pantheon to serve larger customers
• Supports 99.95% uptime across 200,000+ websites
• Reduces cloud infrastructure costs by 40%
• Enables future analytics offerings based on machine learning and big data analytics

Nearly every business needs a web presence—but the vast majority of companies don’t want to be involved in the technical aspects of coding, deployment, hosting, security, and scaling websites. To stay focused on the business value and creative aspects of their websites and avoid managing infrastructure, thousands of companies turn to Pantheon, a website operations and hosting platform that powers over 200,000 websites.

Pantheon promises its customers speed, reliability, and scalability plus world-class collaboration and workflow tools. For five years, the company was able to deliver high service levels in all three areas running its platform on bare-metal virtual cloud servers. However, as its business grew, network links began to saturate under heavy load, risking instability. As Pantheon’s business evolved to focus on servicing some of the largest websites in the world, the company wanted to partner with a more innovative cloud services provider.

“We wanted a partner that could give us what we offer to our own customers: the flexibility to scale smoothly and consume services without building them from scratch,” says David Strauss, CTO, Pantheon. “It was time to move beyond custom containers on managed VMs and extend our cloud strategy to include next-generation technologies for container management and analytics.”

Pantheon evaluated several leading cloud providers and determined that Google Cloud Platform would be the best fit for its business and customers. Engineering had the final say, running a battery of functionality and performance tests at the storage, database, and web server layers.

“In every test our engineers did, Google Cloud Platform came in as better, faster, and more cost effective than the competition,” says Niall Hayes, COO, Pantheon. “We compared MariaDB to Google Cloud SQL and Cassandra to Google Bigtable, and container density improved from 250 to 400 containers per server.”

Migrating 200,000+ sites in 2 weeks

Pantheon wanted to make the transition transparent to its customers, so a fast and smooth migration to Google Cloud Platform was essential. With help from Google, Pantheon completed the migration quickly and moved 500TB of databases, code, and files with zero customer impact.

“We migrated over 200,000 websites to Google Cloud Platform in 2 weeks, including 50,000 that are heavily trafficked and actively developed, and nobody noticed,” says Josh Koenig, Co-founder and Head of Products at Pantheon. “The speed was incredible. There was no downtime, and we filed no additional support tickets with Google during the entire process.”

The platform for platforms

For its content management system runtime environment, Pantheon runs its own homegrown container management technology on Google Compute Engine. To automate scaling for other core services such as its routing layer and distributed file system, it uses Google Kubernetes Engine for cluster management and orchestration.

“Google is the clear leader in Kubernetes and container management, which aligns very well with our open source values and our vision for the future,” says Niall. “With Google Kubernetes Engine we get better resource efficiency, and automated operations and autoscaling take a lot of administration off our plate.”

In addition to smooth scaling, Pantheon and its customers benefit from improved performance and reliability thanks to the high-quality private network offered by Google.

Further, the Google partnership with Fastly enables direct connectivity to Google Cloud Platform to improve performance for edge caching. As a result of these improvements, Pantheon raised its availability service level agreement (SLA) from 99.9% to 99.95% and can now take on even larger customers.

“Google’s network topology, both locally and globally, performs better and more reliably than competing solutions, making Google Cloud Platform the best choice for us and for our customers,” says David. “Google beats any other cloud provider as the best platform-for-platforms.”

Adds Josh: “Google has unbelievable technology around persistence and replication between zones and regions, and that is not something we could find anywhere else. This allows us to offer advanced disaster recovery and failover services to our customers.”

Strengthening customer relationships

Pantheon uses Google BigQuery, a fully managed, cloud-based data warehouse, to integrate with Fastly and analyze website traffic on behalf of its customers. Previously, Pantheon was unable to ingest edge data quickly enough from Fastly, limiting its ability to identify issues and provide the best customer service. Today, Fastly streams logs in real time into Google BigQuery for analysis, giving Pantheon a wealth of insights.

“We use Google BigQuery to identify customers that have outgrown their infrastructure or need to right-size for business growth,” says David. “We can have proactive conversations and add a lot of value to the relationships. Soon, we plan to make Google BigQuery available to our customers so they can better understand their own traffic.”

Adds Niall: “Google Cloud Platform is more data-oriented than other cloud providers, making it a better match for our needs and our customers’ strategic initiatives.”

Integrated, granular security

Pantheon appreciates that Google Cloud services are built for public cloud, with granular security as a core design and development requirement. Employees simply use their G Suite credentials to gain access to Google Cloud Platform infrastructure and services.

“We’ve been a G Suite shop for years because of the paperless collaboration benefits,” says Josh. “G Suite connects our distributed company, and it was very natural to use those same logins for Google Cloud Platform.”

Staying competitive and productive

Moving to Google Cloud Platform opens up new possibilities for services Pantheon can offer to customers in the future, including machine learning and big data analytics, to give them a more complete view of how digital experiences are driving their businesses. Internally, engineers can move faster, do more effective capacity planning, and provide better service as Pantheon moves its products upmarket.

Pantheon expected to save 20% on cloud infrastructure costs by moving to Google Cloud Platform, but was able to double that savings with resource optimization and managed services.

“Since moving to Google Cloud Platform, our platform is more secure, reliable, and scalable than ever. We reduced our cloud infrastructure costs by 40%, and our customers’ sites run 45% faster than industry benchmarks,” says Niall. “Our engineers are Google fans for a reason—they’re happier, more efficient, and more productive on Google Cloud Platform.”

Geospatial data is a critical component for a comprehensive analytics strategy. Whether you are trying to visualize data using geospatial parameters or do deeper analysis or modeling on customer distribution or proximity, most organizations have some type of geospatial data they would like to use – whether it be customer zipcodes, store locations, or shipping addresses. However, converting geographic data into the correct format for analysis and aggregation at different levels can be difficult. In this post, we’ll walk through some examples of how you can leverage the Google Cloud platform alongside Google Cloud Public Datasets to perform robust analytics on geographic data. The full queries can be accessed from this notebook here. 

Public US Geo Boundaries dataset

BigQuery hosts a slew of public datasets for you to access and integrate into your analytics. Google pays for the storage of these datasets and provides public access to the data via the bigquery-public-data project. You only pay for queries against the data. Plus, the first 1 TB per month is free! These public datasets are valuable on their own, but when joined against your own data they can unlock new analytics use cases and save the team a lot of time. 

Within the Google Cloud Public Datasets Program there are several geographic datasets. Here, we’ll work with the geo_us_boundaries dataset, which contains a set of tables that have the boundaries of different geospatial areas as polygons and coordinates based on the center point (GEOGRAPHY column type in BigQuery), published by the US Census Bureau.

Mapping geospatial points to hierarchical areas

Many times you will find yourself in situations where you have a string representing an address. However, most tools require lat/long coordinates to actually plot points. Using the Google Maps Geocoding API we can convert an address into a lat/long and then store the results in the BigQuery table. 

With a lat/long representation of our point, we can join our initial dataset back onto any of the tables here using the ST_WITHIN function. This allows us to check and see if a point is within the specified polygon. 

ST_WITHIN(geography_1, geography_2)

This can be helpful for ensuring standard nomenclature; for example, metropolitan areas that might be named differently. The query below maps each customers’ address to a given metropolitan area name.

  SELECT 
   cust.id as customer_id, 
   metro.name as metro_name 
FROM `looker-private-demo.retail.customers` as cust
,`bigquery-public-data.geo_us_boundaries.metropolitan_divisions` as metro
WHERE ST_WITHIN(ST_GEOGPOINT(cust.longitude, cust.latitude),metro.metdiv_geom)

It can also be useful for converting to designated market area (DMA), which is often used in creating targeted digital marketing campaigns.

  SELECT 
   cust.id as customer_id, 
   dma.dma_name 
FROM `looker-private-demo.retail.customers` as cust
,`bigquery-public-data.geo_us_boundaries.designated_market_area` as dma
WHERE ST_WITHIN(ST_GEOGPOINT(cust.longitude, cust.latitude),dma.dma_geom)

Or for filling in missing information; for example, some addresses may be missing zip code which results in incorrect calculations when aggregating up to the zipcode level. By joining onto the zip_codes table we can ensure all coordinates are mapped appropriately and aggregate up from there.

  SELECT 
   zip.zip_code, 
   count(distinct cust.id) as unique_customers
FROM `looker-private-demo.retail.customers` as cust
,`bigquery-public-data.geo_us_boundaries.zip_codes` as zip
WHERE ST_WITHIN(ST_GEOGPOINT(cust.longitude, cust.latitude),zip.zip_code_geom)
GROUP BY 1

Note that the zip code table isn’t a comprehensive list of all US zip codes, they are zip code tabulation areas (ZCTAs). Details about the differences can be found here. Additionally, the zip code table gives us hierarchical information, which allows us to perform more meaningful analytics. One example is leveraging hierarchical drilling in Looker. I can aggregate my total sales up to the country level, and then drill down to state, city and zipcode to identify where sales are highest. You can also use the BigQuery GeoViz tool to visualize geospatial data!

Aside from simply checking if a point is within an area, we can also use ST_DISTANCE to do something like find the closest city using the centerpoint for the metropolitan area table. 

  SELECT 
cust.id as customer_id, 
ARRAY_AGG(
  metro.name order by ST_DISTANCE(
   ST_GEOGPOINT(cust.longitude, cust.latitude),
  metro.internal_point_geom) asc limit 1)[offset(0)] as metro_name
FROM
`looker-private-demo.retail.customers` as cust
,`bigquery-public-data.geo_us_boundaries.metropolitan_divisions` as metro
GROUP BY cust.id

This concept doesn’t just hold true for points, we can also leverage other GIS functions to see if a geospatial area is contained within areas that are listed in the boundaries datasets. If your data comes into BigQuery as a GeoJSON string, we can convert it to a GEOGRAPHY type using the ST_GEOGFROMGEOJSON function. Once our data is in a GEOGRAPHY type we can do things like check to see what urban area the geo is within – using either ST_WITHIN or ST_INTERSECTS to account for partial coverage. Here, I am using the customer’s zip code to find all metropolitan divisions where the zip code polygon and the metropolitan polygon intersect. I am then selecting the metropolitan area that has the most overlap (or the intersection has the largest area) to be the customer’s metro that we use for reporting.

  SELECT 
   cust.id as customer_id, 
   ARRAY_AGG(
      metro.name order by ST_AREA(
        ST_INTERSECTION(zip.zip_code_geom,metro.metdiv_geom)
      ) desc limit 1)[offset(0)] as metro_name  
FROM
`looker-private-demo.retail.customers` as cust
JOIN `bigquery-public-data.geo_us_boundaries.zip_codes` as zip on      cust.zip=zip.zip_code
,`bigquery-public-data.geo_us_boundaries.metropolitan_divisions` as metro
WHERE ST_INTERSECTS(zip.zip_code_geom,metro.metdiv_geom)
GROUP BY cust.id

The same ideas can be applied to the other tables in the dataset including the county, urban areas and National Weather Service forecast regions (which can also be useful if you want to join your datasets onto weather data).

Correcting for data discrepancy

One problem that we may run into when working with geospatial data is that different data sources may have different representations of the same information. For example, you might have one system that records state as a two letter abbreviation and another using the full name. Here, we can use the state table to join the different datasets.

  SELECT 
   st.state_name, 
   sum(ab.sales+fn.sales) as total_sales 
FROM `bigquery-public-data.geo_us_boundaries.states` as st
LEFT JOIN abbreviated_table as ab on ab.state = st.state
LEFT JOIN fullname_table as fn on fn.state = st.state_name
WHERE COALESCE(ab.state, fn.state) IS NOT NULL
GROUP BY 1

Another example might be using the tables as a source of truth for fuzzy matching. If the address is a manually entered field somewhere in your application, there is a good chance that things will be misspelled. Different representations of the same name may prevent tables from joining with each other or lead to duplicate entries when performing aggregations. Here, I use a simple Soundex algorithm to generate a code for each county name, using helper functions from this blog post. We can see that even though some are misspelled they have the same Soundex code.

Next, we can join back onto our counties table so we make sure to use the correct spelling of the county name. Then, we can simply aggregate our data for more accurate reporting. 

  SELECT
 c.county_name,
 sum(sales) as total_sales
FROM
 table
 JOIN `bigquery-public-data.geo_us_boundaries.counties` as c
 on testing.dq_fm_Soundex(table.county) = testing.dq_fm_Soundex(c.county_name)
WHERE c.state_fips_code = cast(36 as string)
GROUP BY 1

Note that fuzzy matching definitely isn’t perfect and you might need to try different methods or apply certain filters for it to work best depending on the specifics of your data.

The US Geo Boundary datasets allow you to perform meaningful geographic analysis without needing to worry about extracting, transforming or loading additional datasets into BigQuery.
