We are getting ready to launch three new Amazon Elastic Compute Cloud (Amazon EC2) instance types and I am happy to be able to give you a sneak peek at them today.
C7gn Instances are designed for your most demanding network-intensive workloads: network virtual appliances (firewalls, virtual routers, load balancers, and so forth), data analytics, and tightly-coupled cluster computing jobs. They are powered by AWS Graviton3E processors and will support up to 200 Gbps of network bandwidth, along with 50% higher packet processing performance. The c7gn instances will be available in multiple sizes with up to 64 vCPUs and 128 GiB of memory. We are launching the preview today and you can Sign Up Today to join in.
Hpc7g Instances are also powered by AWS Graviton3E processors, with up to 35% higher vector instruction processing performance than the Graviton3. They are designed to give you the best price/performance for tightly coupled compute-intensive HPC and distributed computing workloads, and deliver 200 Gbps of dedicated network bandwidth that is optimized for traffic between instances in the same VPC. The hpc7g instances will be available in multiple sizes with up to 64 vCPUs and 128 GiB of memory. I’ll have more information to share on these instances in early 2023.
R7iz Instances are powered by the latest 4th generation Intel Xeon Scalable Processors (code named Sapphire Rapids) and run at a sustained all-core turbo frequency of 3.9 GHz. With high performance and DDR5 memory, these instances are a perfect match for your Electronic Design Automation (EDA), financial, actuarial, and simulation workloads. They are also great hosts for relational databases and other commercial software that is licensed on a per-core basis. The r7iz instances will be available in multiple sizes with up to 128 vCPUs and 1 TiB of memory. We are launching the instances in preview today and you can Sign up Today to participate.
