EC2 C8gb with 300 Gbps EBS Bandwidth Lands in More Regions!

Hi everyone, Shii-chan here! A Graviton4 instance with serious storage performance just widened its region list!

AWS What's New aws.amazon.com

What was announced?

AWS What's New announced that Amazon EC2 C8gb instances are now generally available in additional regions.

C8gb instances are powered by the latest-generation AWS Graviton4 processors. The newly announced regions are:

  • US East (Ohio)
  • US West (N. California)
  • EU (Frankfurt, Ireland, Paris, Stockholm)
  • Africa (Cape Town)

Why it matters

C8gb stands out for compute plus high EBS performance.

  • Up to 30% better compute performance than Graviton3-based EC2 instances
  • Higher EBS performance than same-sized equivalent Graviton4-based instances

It's a good fit if you want to scale workloads like high-performance file systems, where block storage performance and throughput matter, while keeping costs in mind.

What changes

You can now pick C8gb in more regions, so teams whose region is dictated by data location or latency can consider it more easily.

This is especially good news if you run EBS-bound workloads in the EU or Africa regions!

Dive Deep

Here are the specs from the announcement:

  • Sizes up to 48xlarge
  • Up to 384 GiB of memory
  • Up to 300 Gbps of EBS bandwidth and up to 1600K IOPS
  • Up to 400 Gbps of networking bandwidth
  • Elastic Fabric Adapter (EFA) on 16xlarge, 24xlarge, and 48xlarge, for lower latency and better performance in tightly coupled clusters

You can get started with the AWS Management Console, AWS CLI, or AWS SDKs.

One caveat: the opening region list in the announcement leaves out US East (N. Virginia) and US West (Oregon), while the later list includes them, so the two don't match. Check the AWS documentation for availability before you plan around it.

Wrap-up

  • Graviton4-based EC2 C8gb is now GA in additional regions
  • Up to 30% better compute performance than Graviton3
  • Up to 300 Gbps EBS bandwidth and 1600K IOPS, up to 48xlarge and 384 GiB
  • EFA support on the larger sizes (16xlarge and above)

This one is for anyone with EBS-bound file systems or large clusters!
