Starting today, the general-purpose Amazon EC2 M6a instances are now available in US East (Ohio) and Europe (Frankfurt). Additionally, compute-optimized Amazon EC2 C6a instances are now available in US East (Ohio), Asia Pacific (Mumbai), and Europe (Frankfurt). M6a and C6a instances are powered by 3rd generation AMD EPYC (code named Milan) processors with an all-core turbo frequency of 3.6 GHz. M6a instances deliver up to 35% better price performance compared to M5a instances, while C6a instances deliver up to 15% better price performance compared to C5a instances. Both M6a and C6a instances offer 10% lower cost than comparable x86-based EC2 instances. M6a and C6a instances are built on the AWS Nitro System, a combination of dedicated hardware and lightweight hypervisor, which delivers practically all of the compute and memory resources of the host hardware to your instances. M6a instances are SAP-Certified and a good fit for workloads such as web and application servers, back-end servers supporting enterprise applications, web servers, micro-services, multi-player gaming servers, caching fleets, as well as for application development environments. C6a instances are well suited for compute-intensive applications like batch processing, distributed analytics, high performance computing (HPC), ad serving, highly-scalable multiplayer gaming, and video encoding.
To meet customer demands for increased scalability, M6a and C6a instances provide two new instance sizes, the largest with 192 vCPUs, and 768 GiB on M6a and 384 GiB of memory on C6a, twice the size of the largest M5a and C5a instances. These instances also give customers up to 50 Gbps of networking speed and 40 Gbps of bandwidth to the Amazon Elastic Block Store, which is more than twice that of M5a and C5a instances. Customers can use Elastic Fabric Adapter on the 48xlarge size, which enables low latency and highly-scalable inter-node communication. For optimal networking performance on these new instances, an Elastic Network Adapter (ENA) driver update may be required. For more information on optimal ENA drivers for M6a and C6a, see this article.
With these additional regions, M6a and C6a instances are available in the following AWS Regions: US East (N. Virginia, Ohio), US West (Oregon), Asia Pacific (Mumbai), and Europe (Frankfurt, Ireland). These instances can be purchased as Savings Plans, Reserved, On-Demand, and Spot instances. To get started, visit the AWS Management Console, AWS Command Line Interface (CLI), and AWS SDKs.
