Hi, it's me, Shiichan! I found a new update from AWS What's New about memory-optimized instances, so let me share it with you.

What was announced?

According to AWS What's New, Amazon EC2 R8id instances are now available in six more regions:

  • Asia Pacific (Mumbai)
  • Asia Pacific (Malaysia)
  • Asia Pacific (Sydney)
  • Canada (Central)
  • Europe (Ireland)
  • Europe (Stockholm)

R8id is a memory-optimized family with local NVMe SSD storage, and users in these regions finally get it as an option.

The story so far

R8id was already available in other regions, just not in these six. The previous generation, R6id, was available there, so teams running memory- and storage-heavy workloads had to mix generations depending on the region.

What changes

Teams building infrastructure in these regions can now move straight to the latest R8id generation. If you're running in-memory databases, real-time big data analytics, or large in-memory caches, you can now use a consistent instance generation no matter which of these regions you're in.

Dive Deep

Here's how R8id compares to R6id:

  • Local storage: up to 22.8 TB of NVMe SSD (3x more than R6id)
  • Memory bandwidth: up to 3.3x higher
  • Overall performance: up to 43% better than R6id

The 24xlarge, 48xlarge, metal-24xl, and metal-48xl sizes also support Elastic Fabric Adapter (EFA) networking. On top of that, EC2 instance bandwidth weighting configuration now lets you adjust network and Amazon EBS bandwidth allocation in 25% increments, so you can shift bandwidth toward whichever resource your workload needs most.

You can purchase these instances via Savings Plans, On-Demand, or Spot.

Wrap-up

  • Amazon EC2 R8id is now available in six more regions: Mumbai, Malaysia, Sydney, Canada Central, Ireland, and Stockholm
  • Up to 3x more local storage (22.8 TB), up to 3.3x memory bandwidth, and up to 43% better overall performance vs. R6id
  • The largest sizes (24xlarge and up) support EFA networking
  • EC2 instance bandwidth weighting lets you adjust network/EBS bandwidth in 25% increments

If you're running memory-intensive workloads like in-memory databases or large caches in these regions, this one's worth checking out!
