Supported memory and CPU combinations

{: #mem-cpu-combo}

{{site.data.keyword.codeenginefull}} applications and jobs consume CPU and memory. These amounts can vary, depending on if your app is compute-intensive, memory-intensive, or balanced. {: shortdesc}

For more information about memory or CPU limitations, see Limits and quotas for {{site.data.keyword.codeengineshort}}.

See the following table for valid combinations of vCPU and memory.

CPU-intensive	Balanced	Memory-intensive
0.125 vCPU 0.25 GB	0.125 vCPU 0.5 GB	0.125 vCPU 1 GB
0.25 vCPU 0.5 GB	0.25 vCPU 1 GB	0.25 vCPU 2 GB
0.5 vCPU 1 GB	0.5 vCPU 2 GB	0.5 vCPU 4 GB
1 vCPU 2 GB	(default) 1 vCPU 4 GB	1 vCPU 8 GB
2 vCPU 4 GB	2 vCPU 8 GB	2 vCPU 16 GB
4 vCPU 8 GB	4 vCPU 16 GB	4 vCPU 32 GB
6 vCPU 12 GB	6 vCPU 24 GB
8 vCPU 16 GB	8 vCPU 32 GB

Your existing apps and jobs might be using other memory and CPU combinations, and those will remain unaffected. However, these other combinations are not valid and only the valid combinations are supported. Therefore, any new apps or jobs as well as any changes to existing apps or jobs must comply with the list of valid choices. {: important}
