Scaling

As your needs grow, you can adjust the resources allocated to a service instance. This page describes scaling in general. The available options depend on the service and offering. See the relevant page in the Service Catalog for service-specific details.

What you can scale

  • Compute: change the compute plan (CPU and memory) of an instance.
  • Storage: increase the storage size allocated to an instance.
  • Replicas: for services that support it, change the number of replicas (for example to enable high availability).

How scaling works

Scaling is done by updating the service instance in the portal. The change is applied to the running instance:

  • Storage can only be increased but not decreased.
  • A compute plan change may cause a short restart, depending on the service.
  • Replica changes depend on the high-availability capabilities of the service.

Resource allocations and pricing are defined by the compute plan. See Compute Plans & SLAs.
