r7i.large

r7i.large is AWS's memory-optimized EC2 size at 2 vCPU and 16 GiB. In the name, "r" stands for RAM, "7" is the generation, "i" marks Intel processors and "large" is the size within the r7i family. It runs on Intel Xeon Scalable (Sapphire Rapids) at 3.2 GHz, and AWS introduced it in October 2023. AWS has since shipped r8i and r9g; r8i.large is the direct replacement at this size. On Rackspace Spot the same shape is mh.vs2.medium — 2 vCPU, 16 GiB, matched on both dimensions, about 92% below the US East (N. Virginia) on-demand rate.

When to use it
Good for
  • ●Large JVM heaps and application servers that hold state
  • ●OLAP and business intelligence query engines
  • ●Real-time analytics over hot datasets
  • ●Workloads that fit inside 16 GiB of RAM
  • ●Small, steady services that do not need more than 2 vCPU
  • ●Network-heavy services — AWS rates this size at Up to 12.5 Gigabit
Avoid if
  • ●Starting a new deployment. r8i.large is the newer generation at this size.
  • ●The working set needs more than 16 GiB of RAM
  • ●GPU or FPGA acceleration is needed
  • ●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
  • ●Local NVMe or instance-store disk is a hard requirement
Stop overpaying AWS. This compute costs $97/mo on AWS vs $8/mo on Rackspace Spot.
  • 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.
