c7i.large

c7i.large is AWS's compute-optimized EC2 size at 2 vCPU and 4 GiB. In the name, "c" stands for compute, "7" is the generation, "i" marks Intel processors and "large" is the size within the c7i family. It runs on Intel Xeon Scalable (Sapphire Rapids) at 3.2 GHz, and AWS introduced it in September 2023. AWS has since shipped c8i and c9g; c8i.large is the direct replacement at this size, scoring 42,900 CoreMark/s against this instance's 39,481 — roughly 9% more throughput for the same vCPU count. On Rackspace Spot the same shape is ch.vs2.medium — 2 vCPU, 4 GiB, matched on both dimensions, $0.089/hr on AWS in US East (N. Virginia), from $0.002/hr on Rackspace Spot.

When to use it
Good for
  • ●Game servers and matchmaking
  • ●Batch processing and CI/CD runners
  • ●Video encoding and transcoding
  • ●Workloads that fit inside 4 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. c8i.large is the newer generation at this size.
  • ●The working set needs more than 4 GiB of RAM
  • ●More than 2.00 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
  • ●GPU or FPGA acceleration is needed
  • ●Memory-hungry applications. A memory-optimized family gives more RAM per dollar.
c7i.large runs $65/mo on AWS on-demand. The equivalent on Rackspace Spot: $1/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.
