From Rob Pike on Google’s Open Source Blog:

In the past year, we’ve posted sixteen case studies from end users around the world talking about how they use Go to build fast, reliable, and efficient software at scale. Today, we are adding three new case studies from teams inside Google:

• Core Data Solutions: Google’s Core Data team replaced a monolithic indexing pipeline written in C++ with a more flexible system of microservices, the majority of them written in Go, that help support Google Search.
• Google Chrome: Mobile users of Google Chrome in lite mode rely on the Chrome Optimization Guide server to deliver hints for optimizing page loads of well-known sites in their geographic area. That server, written in Go, helps deliver faster page loads and lowered data usage to millions of users daily.
• Firebase: Google Cloud customers turn to Firebase as their mobile and web hosting platform of choice. After joining Google, the team completely migrated its backend servers from Node.js to Go, for the easy concurrency and efficient execution.
