Stop/Start

danger

Currently a9s PostgreSQL is the only Data Service that supports the usage of the Stop/Start feature.

Trying to apply the information contained on this document to an a9s Data Service aside from the ones mentioned above can leave the Service Instances in an irrecuperable state.

caution

This feature is currently in Beta.

The Stop/Start feature allows an Application Developer to remove the VMs belonging to a Service Instance when necessary and add them again later without losing any persistent data. This allows them to save on infrastructure costs during periods when the Service Instance is not needed.

Enable the Stop/Start Feature

The Stop/Start feature is disabled by default in the a9s Public API. The Ops file enable-stop-start-feature.yml can be used to enable the feature by applying it to the different a9s Data Services.

note

To disable the Stop/Start feature, the a9s Data Services need to be deployed once more, without the Ops file.

warning

It is not recommend to leave any a9s Service Instances with the stopped status, if the feature is to be disabled. Thus, before disabling the feature, make sure to start all Service Instances that are currently stopped are either properly started or deleted.
