Powering a Service Instance Virtual Machine on or off is the equivalent of powering a physical machine on or off.

Powering Off a Service Instance

You may choose to power off a Service Instance in your development and testing environent to save costs.

Powering off a Service Instance is an on-demand operation. In addition to disrupting connectivity between the Service Instance and client applications, the downtime affects currently running management tasks as follows:

  • If an automated task is running when the power down request is made, the task may fail, but will be automatically re-initiated in the next maintenance window if/when the instance is powered back on.
  • If the power down operation coincides with other running on-demand tasks, those tasks may also fail, and you may be required to re-initiate them if/when the instance is powered back on.

You can clone or delete a powered off Service Instance. No other automated or manual management tasks can be performed on a powered off Service Instance, and replication to and from the instance will cease to work.

Prerequisites

Before you attempt to power off a Service Instance, ensure that it is currently powered on.
