Description

Add COMPUTE8_AMD and C8A enum values to InstanceClass for the compute-optimized C8a instances based on 5th generation AMD EPYC processors.

C8a instances were announced but not yet available in CDK.

Closes #36722

Changes

  • Added InstanceClass.COMPUTE8_AMD and InstanceClass.C8A enum values
  • Added mapping entries in the InstanceType class
  • Added unit tests

Testing

Unit tests added to verify both C8A and COMPUTE8_AMD resolve to c8a.* instance type strings.

Exemption Request - This change only adds new enum values to InstanceClass (C8A/COMPUTE8_AMD) and their mapping. No new API surface or README-documentable behavior is introduced. Unit tests are already included.
