The M9g database instances, leveraging AWS’s custom Graviton5 processors, provide increased compute power and networking bandwidth, with new large instance sizes supporting up to 192 vCPUs and significant storage throughput. These instances improve performance and cost efficiency compared to Graviton4 counterparts across supported open source databases.

Availability covers key AWS regions including US East (N. Virginia, Ohio), US West (Oregon), and Europe (Frankfurt). Performance gains and efficiency depend on database engine, version, and workload characteristics as per AWS claims.
