You can now launch Amazon EMR clusters with the next generation of compute optimized C5n instances, and the new AMD-based general purpose M5a instances and memory optimized R5a instances from the Amazon EC2 family. These instances are available for EMR clusters with release 5.20.0 and later. Compute Optimized C5n instances offer network bandwidth of up to 100Gbps and are ideal for communication-intensive distributed analytics and compute-heavy big-data applications that require high-network throughput and high-performance computing. The new AMD powered M5a and R5a instances are variants of Amazon EC2’s general purpose (M5) and memory optimized(R5) instance families that cost 10% lower than comparable instances. M5a instances offer a balance of compute, memory and networking and cater to a broad range of workloads. R5a instances have high memory to vCPU ratio and are ideal for memory-intensive analytics workloads. These instances are available in various sizes, to learn more about these instances please visit the Amazon EC2 instance page. For Amazon EMR pricing for these instances, visit the Amazon EMR pricing page.

Amazon EMR supports these instances in the following regions:

C5n instances are supported in the AWS US East (N.Virginia and Ohio), AWS US West (Oregon), AWS Europe (Ireland), and AWS GovCloud (US) regions.

M5a and R5a instances are supported in the AWS US East (N.Virginia and Ohio), AWS US West (Oregon), AWS Europe (Ireland), and AWS Asia Pacific (Singapore) regions.
