[New Feature] In this blog post, I have discussed the new feature that has been introduced by Oracle on 23rd April 2020 i.e., Variable(Flexible) OCPU Count.
Oracle has recently introduced the feature of Flexible Compute Shape in which you can customize the number of OCPUs present according to the workload that will run on the instance.
A new AMD shape with a customizable OCPU count is now available for virtual machines. The amount of memory, network bandwidth, and number of VNICs will scale accordingly.
A compute shape is a pre-defined configuration that determines the number of CPUs, amount of memory, and other resources allocated to a newly created instance. Shapes are available for both BM & VM instances.
Compute is one of the core services of OCI, if you want to know more about Compute check out K21Academy’s post here.
An OCPU is CPU capacity equivalent of one physical core of an Intel Xeon processor with hyperthreading enabled whereas, in Intel Xeon processor, each OCPU corresponds to two hardware execution threads, known as vCPUs.
Note: High-performance computing (HPC) shapes, X5-based and X6-based shapes, and AMD shapes are NOT available in Government Cloud realms. To know more about Region & Realm in Oracle Cloud, check here.
A shape in which you can customize the number of OCPUs is known as Flexible shape. If you have created a VM instance using flexible shape, you can later increase the number of OCPUs are per the workload. When you increase the OCPU, the network bandwidth, memory, and number of VNICs also increase proportionally. Example of flexible shape – VM.Standard.E3.Flex shape(Min 1 and Max 64 OCPU).
Flexible shapes are NOT supported in all regions.
- Germany Central (Frankfurt)
- Japan East (Tokyo)
- US East (Ashburn)
- US West (Phoenix)
