Introducing Amazon EC2 C6id instances
Amazon Web Services (AWS) announces the general availability of the new compute optimized Amazon Elastic Compute Cloud (Amazon EC2) C6id instances. C6id instances are powered by third generation Intel Xeon Scalable processors (code name Ice Lake) with an all-core turbo frequency of 3.5 GHz, equipped with up to 7.6 TB of local NVMe-based solid state drive (SSD) block level storage, and deliver up to 15% better price performance compared to C5d instances. Compared to previous generation instances, C6id instances offer up to 138% higher TB storage per vCPU and 56% lower cost per TB. C6id instances also come with always-on memory encryption by using Intel Total Memory Encryption (TME). Like all modern EC2 instances, C6id instances are built on [AWS Nitro System](/ec2/nitro/), a combination of dedicated hardware and lightweight hypervisor, which delivers most of the compute and memory resources of the host hardware to your instances. C6id instances are ideal for compute-intensive workloads, including those that need access to high-speed, low-latency local storage, such as video encoding, image manipulation, and other forms of media processing. C6id instances will also benefit applications that need temporary storage of data, such as batch and log processing, and applications that need caches and scratch files. To meet customer demands for increased scalability, C6id instances provide a new instance size (32xlarge) with 128 vCPUs and 256 GiB of memory (both 33% more than the largest previous generation instances) and up to 9% higher memory bandwidth per vCPU compared to previous generation instances. C6id instances also provide customers up to 50 Gbps of networking speed and 40 Gbps of bandwidth to [Amazon Elastic Block Store](/ebs/), twice that of comparable previous gen instances. Customers can use [Elastic Fabric Adapter](/hpc/efa/) on the 32xlarge size, which enables low-latency and highly scalable inter-node communication. For optimal networking performance on these new instances, the latest Elastic Network Adapter (ENA) driver might be required. For more information about the optimal ENA driver for C6id, see [What do I need to do before migrating my EC2 instance? ](https://aws.amazon.com/premiumsupport/knowledge-center/migrate-to-gen6-ec2-instance/) These instances are generally available today in these AWS Regions: US East (Ohio), US East (N. Virginia), US West (Oregon), and Europe (Ireland). C6id instances are available in 10 sizes, with 2, 4, 8, 16, 32, 48, 64, 96, and 128 vCPUs, including metal size. Customers can purchase the new instances through Savings Plans, Reserved Instances, On-Demand Instances, and Spot Instances.
