App Engine Application Platform | Google Cloud Open and familiar languages and tools Build and deploy apps quickly using popular languages or bring your own language runtimes and frameworks. You can also manage resources from the command line, debug source code, and run API back ends easily. Just add code Focus on writing code without having to manage underlying infrastructure. Protect your apps from security threats using firewall capabilities, IAM rules, and managed SSL/ TLS certificates. Pay only for what you use Operate in a serverless environment without worrying about over or under provisioning. App Engine automatically scales depending on your app traffic and consumes resources only when your code is running. Key features All features Popular languages Build your application in Node.js, Java, Ruby, C#, Go, Python, or PHP—or bring your own language runtime. Open and flexible Custom runtimes allow you to bring any library and framework to App Engine by supplying a Docker container. Fully managed A fully managed environment lets you focus on code while App Engine manages infrastructure concerns. Powerful application diagnostics Use Cloud Monitoring and Cloud Logging to monitor the health and performance of your app and Cloud Debugger and Error Reporting to diagnose and fix bugs quickly. Application versioning Easily host different versions of your app, and easily create development, test, staging, and production environments. Traffic splitting Route incoming requests to different app versions, A/B test, and do incremental feature rollouts. Application security Help safeguard your application by defining access rules with App Engine firewall and leverage managed SSL/TLS certificates by default on your custom domain at no additional cost. Services ecosystem Tap a growing ecosystem of Google Cloud services from your app including an excellent suite of cloud developer tools.
