Amazon EC2 C7i and C7i-flex instances

Compute optimized instances powered by 4th Generation Intel Xeon Scalable processors

Why Amazon EC2 C7i and C7i-flex instances?

Amazon Elastic Compute Cloud (Amazon EC2) C7i-flex and C7i instances are next-generation compute optimized instances powered by custom 4th Generation Intel Xeon Scalable processors (code named Sapphire Rapids) and feature a 2:1 ratio of memory to vCPU. EC2 instances powered by these custom processors, available only on AWS, offer the best performance among comparable Intel processors in the cloud – up to 15% better performance than Intel processors utilized by other cloud providers.

C7i-flex instances provide the easiest way for you to get price performance benefits for a majority of compute-intensive workloads. They deliver up to 19% better price performance compared to C6i instances. C7i-flex instances offer the most common sizes, from large to 16xlarge, with up to 64 vCPUs, 128 GiB memory, and are a great first choice for applications that don't fully utilize all compute resources. C7i-flex instances are designed to seamlessly run the most common compute-intensive workloads, including web and application servers, databases, caches, Apache Kafka, and Elasticsearch.

C7i instances offer price performance benefits for workloads that need larger instance sizes (up to 192 vCPUs and 384 GiB memory) or continuous high CPU usage. C7i instances are ideal for workloads including batch processing, distributed analytics, high performance computing (HPC), ad serving, highly scalable multiplayer gaming, and video encoding. C7i instances deliver up to 15% better price performance compared to C6i instances.

Introducing Amazon EC2 Flex instances

Cost optimize with new Amazon EC2 Flex instances

Many customers do not fully utilize all the compute resources of an EC2 instance. Those customers are therefore paying for performance that they don’t need. Amazon EC2 C7i-flex instances offer the easiest way to achieve improved price performance for a majority of compute-intensive workloads. Amazon EC2 Flex instances efficiently use compute resources with the ability to scale up to full compute performance a majority of the time. Flex instances are purpose-built to optimize cost and performance.
