Compute Shape

A shape is a template that determines the number of OCPUs, amount of memory, and number of VNICs that are allocated to a compute instance. Compute Cloud@Customer offers a flexible shape that lets you customize the number of OCPUs and the amount of memory for an instance. This flexibility lets you create instances that meet your workload requirements, while optimizing performance and using resources efficiently.

You choose the shape configuration when you create an instance. See Creating an Instance.

Attention

When you create instances using any of the platform images that are provided with Compute Cloud@Customer, select only the VM.PCAStandard.E5.Flex shape.

The following table lists the number of OCPUs and the amount of memory you can configure using the VM.PCAStandard.E5.Flex Shape.

The number of OCPUs you select determines the maximum VNIC attachments and the network bandwidth for the instance.
