Comparison
| Aspect | Before / Alternative | After / This |
|---|---|---|
| Processor Gen | Older memory-optimized instances utilizing fifth generation or older Intel Xeon processors | Custom sixth generation Intel Xeon Scalable processors |
| Network Performance | Standard bandwidth constraints on older instances | Enhanced networking support with double-letter designations for high-speed network/EBS performance |
| Regional Availability | Limited to initial launch regions | Expanded to AWS Asia Pacific (Tokyo) and Europe (Frankfurt, Ireland) regions |
Action Checklist
- Verify instance type quota in Tokyo, Frankfurt, and Ireland regions Request a quota limit increase if launching these new instances for the first time
- Test workloads with sixth-generation Intel Xeon features Ensure your AMI and kernel support the latest microarchitectural optimizations
- Update infrastructure-as-code templates Modify Terraform or CloudFormation configurations to reference r8in, r8ib, r8idn, or r8idb types
