Overview of bundled services

All of the services described in this section are bundled into the first-generation runtimes, such as Java 8.

If you are updating from a App Engine first-generation runtime to a second-generation runtime, such as Java 11, you have a few options:

  • You can access several of these bundled services through idiomatic libraries for supported second-generation runtimes.
  • You can use full-featured Google Cloud products that offer similar functionality as these bundled services.
  • For bundled services that are not available as separate products in Google Cloud, you can use third-party providers or other workarounds.

To learn more about these options for migrating your app, see Migrating your App Engine app from Java 8 to Java 11.
