Resizing the BMC Helix Service Management deployment

You can resize BMC Helix Service Management deployment to facilitate scaling up and down of your environment. Resize your  BMC Helix Service Management by changing the deployment size. You can increase or decrease the deployment size.

Scenario

Apex Global uses BMC Helix Service Management in a Compact deployment size and want to expand the size to manage additional user load. A larger deployment size provides more pod replicas and users. A system administrator in Apex Global verifies the number of pod replicas and users supported with the deployment sizes, Small, Medium, and Large. The system administrator analyzes that the Medium deployment size meets your user load requirements, and then changes the deployment size to Medium by re-running the deployment pipelines.
