AWS announced that EC2 R8i and R8i-flex are available in the AWS European Sovereign Cloud (Germany) region.
The change is regional availability, not a demonstrated performance or cost result for every deployment. Here is how the two families differ in AWS’s description, and what to verify before choosing one.

What changed in the announcement?
In its notice published September 25, 2026, AWS announced that Amazon EC2 R8i and R8i-flex instances are available in the AWS European Sovereign Cloud (Germany) region. The notice’s publication date is known; a separate rollout date has not been verified.
For a reader considering memory-intensive workloads in that region, the announcement puts both families on the list of options to examine. It does not establish that a needed size can be launched in a particular account, or that a workload will achieve a particular performance or cost result.

How does AWS distinguish R8i-flex from R8i?
AWS describes the families in terms of resource use and instance size:
- R8i-flex is a memory-optimized Flex family that AWS positions for applications that do not fully use all compute resources. Its stated family size range runs from large through 16xlarge.
- R8i is positioned for memory-intensive workloads, particularly those needing the largest sizes or sustained high CPU use. AWS describes 13 family sizes, including two bare-metal sizes and 96xlarge.
These descriptions help narrow the choice, but a family’s stated size range is not confirmation that every size is launchable in the intended account in Germany.
Do AWS’s comparison figures predict a deployment’s results?
No. AWS claims that R8i and R8i-flex offer up to 15% better price-performance and 2.5 times the memory bandwidth compared with previous-generation Intel-based instances. It also claims 20% higher performance than R7i and, compared with R7i for named workloads, up to 30% faster PostgreSQL databases, 60% faster NGINX web applications and 40% faster AI deep-learning recommendation models.
Those are AWS’s comparisons, not independently verified results for a deployment in the newly announced region. In particular, an “up to” figure for a named workload should not be treated as the expected gain for a different application—or as a measured cost saving.
What should a deployment decision depend on?
AWS lists Savings Plans, On-Demand and Spot as purchase options, but that list does not give the applicable price or effective cost of a particular deployment. The useful distinction is between a family being announced for a region and the conditions under which it meets a specific deployment’s needs. Check:
- Whether the required R8i or R8i-flex sizes are available to the intended account in the Germany region.
- Which purchase terms and prices apply to the proposed deployment.
- Whether results from the actual workload meet its performance requirements.
If any of those answers is unfavorable or still unknown, the regional announcement alone is not a sufficient basis for choosing the instance family.
