Amazon EC2 R6a Instances

Run memory-optimized instances powered by 3rd generation AMD EPYC processors

Why Amazon EC2 R6a Instances?

Amazon EC2 R6a instances are powered by 3rd generation AMD EPYC processors and deliver up to 35% better price performance compared to R5a instances and 10% lower cost than comparable x86-based Amazon EC2 instances. R6a instances feature an 8:1 ratio of memory to vCPU, just like R5a instances, and support increased sizes up to 192 vCPUs per instance. These instances are SAP-Certified and are an ideal fit for memory-intensive workloads, such as SQL and NoSQL databases; distributed web scale in-memory caches, such as Memcached and Redis; in-memory databases and real-time big data analytics, such as Apache Hadoop and Apache Spark clusters; and other enterprise applications.
