We are excited to announce the availability of the m4.16xlarge, the largest instance size in the latest generation of EC2 General Purpose instances, featuring 64 vCPUs and 256 GiB of memory. The m4.16xlarge offers a balance of compute, memory, and network resources, and is a good choice for many applications including databases, data processing tasks, cluster computing, and web servers that require high computational horsepower or memory size.
