AWS announces the general availability of Amazon Elastic Compute Cloud (Amazon EC2) C6in instances. C6in instances are powered by 3rd Generation Intel Xeon Scalable processors with an all-core turbo frequency of up to 3.5 GHz. They are the first x86-based Amazon EC2 compute-optimized instances offering up to 200 Gbps network bandwidth. C6in instances deliver up 2x more network bandwidth, and 2x higher packet performance than comparable C5n instances. C6in 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 for better overall performance and security. You can take advantage of the higher network bandwidth to scale the performance of applications, such as network virtual appliances (firewalls, virtual routers, load balancers), Telco 5G User Plane Function (UPF), data analytics, high performance computing (HPC), and CPU based AI/ML workloads.
To meet customer demands for increased scalability, C6in instances are available in 9 different instances with up to 128 vCPUs and 256 GiB of memory, which is 78% larger than the largest C5n instances. Each instance vCPU has 9% higher memory bandwidth compared to C5n instances. C6in instances also deliver up to 80 Gbps of Amazon Elastic Block Store (Amazon EBS) bandwidth and up to 350K input/output operations per second (IOPS), the highest Amazon EBS performance across EC2 instances. C6in instances also offer Elastic Fabric Adapter (EFA) networking support on the 32xlarge size. EFA support enables lower latency and improved cluster performance for workloads deployed on tightly coupled clusters, such as distributed computing and HPC.
These new instances are available in the following AWS Regions: US East (Ohio), US East (N. Virginia), US West (Oregon), and Europe (Ireland).
