GAE - replacement for vm:true flag on app.yaml

I've been using the standard environment setting vm:true on my app.yaml

I know that this flag is now deprecated and I won't be able to use it in the future... I also know that Flexible Environment is currently in Beta, so my question is, will env:flex be the replacement for vm:true? If so will it be stable by then?

Thanks

Solution

  • In general Beta products come with no SLA and this is highlighted on App Engine Flexible Environment:

    This is a Beta release of the App Engine flexible environment. It is not covered by any SLA or deprecation policy and the implementation may change, possibly in backward-incompatible ways. It is not recommended for production use.

    However, there is this note in Upgrading to the Latest App Engine Flexible Environment Beta Release (emphasis mine):

    All applications created in the vm:true environment will continue to work for at least 6 months after the App Engine flexible environment becomes generally available. At that point, all customers need to switch to the env:flex environment.
