Manage categories and tags

Compute Categories and Tags are used to specify which application instances run on a compute node. An instance can be migrated from one compute node to another by modifying the compute category or tags of the instance.

Migrating an instance from one compute node to another involves zero downtime, continuous service availability, and transaction integrity. The ThinkAgile CP Cloud Controller VNC console to an instance uses a URL that includes the compute node's IP address. When an instance migrates to a new compute node, the VNC console will automatically close since the URL is no longer valid, and reopening it will open a URL including the new compute node's IP address.
