r7gd.large

The r7gd.large is a memory-optimized AWS EC2 instance: 2 vCPU and 16 GiB of memory, 8.00 GiB per vCPU. In the name, "r" stands for RAM, "7" is the generation, "gd" marks AWS Graviton (ARM) processors and local NVMe storage and "large" is the size within the r7gd family. It runs on AWS Graviton3 Processor at 2.5 GHz, and AWS introduced it in July 2023. AWS has since shipped r8gd and r9gd; r8gd.large is the direct replacement at this size. Rackspace Spot's mh.vs2.medium is a like-for-like substitute at 2 vCPU and 16 GiB, about 92% below the US East (N. Virginia) on-demand rate.

Match qualityx86 substitution

r7gd.large is Graviton (arm64). Rackspace Spot does not have arm64 servers, so mh.vs2.medium is an x86_64 substitute with similar specs.

You will need x86 builds of your container images. Most software rebuilds without changes, but anything with compiled native code needs a real rebuild rather than a retag. Speed per core also differs between the two chips, so it is worth testing before deciding how many nodes to run.

No local diskr7gd.large comes with 1 × 118 GB NVMe SSD attached to the machine. Spot nodes use network storage only, so that disk doesn't come with it. If you were using it as fast scratch space, you'd move to a persistent volume or object storage, which are slower to read.

When to use it
Good for
  • ●In-memory caches such as Redis and Memcached
  • ●Large JVM heaps and application servers that hold state
  • ●OLAP and business intelligence query engines
  • ●Workloads that fit inside 16 GiB of RAM
  • ●Jobs that want 1 × 118 GB of local NVMe scratch space
  • ●Network-heavy services — AWS rates this size at Up to 12.5 Gigabit
Avoid if
  • ●Starting a new deployment. r8gd.large is the newer generation at this size.
  • ●The working set needs more than 16 GiB of RAM
  • ●You cannot rebuild x86-only binaries or vendor images for aarch64
  • ●CPU-bound work. You are paying for memory this workload will not use.
  • ●More than 8.00 GiB of RAM per vCPU is needed — that ratio is fixed for the whole family
  • ●GPU or FPGA acceleration is needed
r7gd.large runs $99/mo on AWS on-demand. The equivalent on Rackspace Spot: $8/mo.
  • Spot sells spare capacity at market prices. It is the cheapest compute on the internet.
  • Prices are set by supply and demand. You pay what the market decides.
  • Compute is delivered as fully managed Kubernetes. All infrastructure is taken care of.
  • Egress costs $0.01/GB after the free allowance. AWS charges $0.09/GB.
