Change the Shape of an Instance
A shape is a resource profile that specifies the number of OCPUs and the amount of memory to be allocated to an instance in Oracle Cloud Infrastructure Compute Classic. The shape determines the type of disk drive that your instance uses.
You specify the shape of an instance while creating the instance. However, if your instance is managed by an orchestration, then you can change the shape of an instance even after the instance has been created. This is useful if you find that your application workload has increased and you would like to add OCPUs and memory to your instance.
To verify the shape your instance uses, you can view the appropriate orchestration. Alternatively, go to the Instances page and view the details of the instance.
