App Engine은 두 개의 Java 애플리케이션용 환경을 제공합니다(표준 환경과 가변형 환경). 두 환경 모두 똑같이 코드 중심의 개발자 워크플로를 사용하고, 증가하는 수요를 처리하기 위해 빠르고 효율적으로 확장할 수 있으며, Google의 입증된 서비스 기술을 사용하여 웹, 모바일, IoT 애플리케이션을 최소한의 운영 오버헤드로 빠르게 빌드할 수 있습니다. 두 환경에는 공통점이 많지만 몇 가지 중요한 차이점이 있습니다.

Both environments have the same code-centric developer workflow, scale quickly and efficiently to handle increasing demand, and enable you to use Google's proven serving technology to build your web, mobile, and IoT applications quickly and with minimal operational overhead. While the available environments have a lot in common, they differ in a few important ways. \n\nChoose your preferred environment\n---------------------------------\n\n### Standard environment\n\n- Optimized to scale nearly instantaneously to handle huge traffic spikes.\n\n- Most cost-effective for applications that have significant periods where they\n are not serving traffic.\n\n- OpenJDK based Java runtime supports the standard public Java library.\n\n- Doesn't impose a security manager--your code won't be restricted by Java\n permissions issues.\n\n- [Free tier](/appengine/pricing).\n\n- Ubuntu OS\n\n- The Java 8 runtime is [no longer supported](/appengine/docs/standard/lifecycle/support-schedule#java).\n\n[View Docs](/appengine/docs/standard/java-gen2/runtime) \n\n### Flexible environment\n\n- Full [open source](http://github.com/GoogleCloudPlatform/) language runtimes.\n\n- Use any framework, library, or binary of your choice.\n\n- Code is portable to anywhere that supports Docker containers.\n\n- Most cost-effective for applications that serve traffic continuously.\n\n- No free tier. Application always has a minimum number of running instances.\n Most cost-effective for applications that serve traffic continuously.\n\n- Ubuntu OS\n\n[View docs](/appengine/docs/flexible/java/dev-jetty9) \n\nChoosing an environment\n-----------------------\n\nYou can run an App Engine application in two environments, the standard environment and the flexible environment.
