The Google App Engine Flexible environment, which transitioned from Beta to GA a couple of months ago allows developers to focus on doing what they do best, writing code. Based on Google Compute Engine, the App Engine flexible environment automatically scales your app up and down while balancing the load.

 

Microservices, authorization, SQL and NoSQL databases, traffic splitting, logging, versioning, security scanning, and content delivery networks are all supported natively. In addition, the App Engine flexible environment allows you to customize the runtime and even the operating system of your virtual machine using Dockerfiles.
