Elastic Compute Service:Compatibility between Intel instance types and operating systems

Last Updated:Feb 21, 2024

This topic describes the versions of the operating system images that are compatible with eighth-generation Intel instance types.

Background information

Eighth-generation Intel instance types use fourth-generation Intel® Xeon® Scalable (Sapphire Rapids) processors, and are built based on the x86 architecture. The following instance families are eighth-generation Intel instance families:

  • g8i, general-purpose instance family

  • c8i, compute-optimized instance family

  • r8i, memory-optimized instance family

For more information, see Overview of instance families.

Operating System Compatibility and Intel® Xeon® Scalable Processors

Suggestions on how to use Intel instance types

When you purchase eighth-generation Intel instance types, we recommend that you use the operating system versions supported by eighth-generation Intel instance types, as described in the preceding table. If you want to use an operating system version that is not described in the preceding table, we recommend that you perform one of the following operations:

  • Select an instance type that supports the operating system version that you want to use.

  • Use a community image that contains the operating system version that you want to use. For more information, see Create an ECS instance by using a community image.


Specific features of the processors that are used by Intel instance types are not supported by earlier operating system versions. If you use operating system versions that are not described in the preceding table together with eighth-generation Intel instance types, proceed at your own risk. You can determine the operating system version that you need based on your applications.
