Summary

Added documentation for new C7i and R7i instance types, including their compute/memory specifications and use cases for AWS DMS workloads.

Security assessment

The changes introduce new instance types and describe performance improvements for data migration tasks. There is no mention of security vulnerabilities, patches, or security-specific configurations. The updates focus on compute capabilities and workload suitability rather than security controls or mitigations.

+  * C7i instances offer better compute performance over comparable previous generation instances. For AWS DMS workloads, C7i instances excel at accelerating data transformation processes, handling compute-heavy schema conversions, and maintaining consistent throughput during high-volume migration tasks. These instances provide an ideal balance of compute performance that require sustained CPU performance.
+
+  * R7i instances offer better compute performance over comparable previous generation instances, combined with high memory capacity for memory-intensive workloads. For AWS DMS workloads, R7i instances are particularly well-suited for tasks involving large databases that process high volumes of concurrent database transactions, enabling efficient handling of memory-intensive replication scenarios and complex data validation processes that require substantial memory buffers.
