c8id.large

The c8id.large is a compute-optimized AWS EC2 instance: 2 vCPU and 4 GiB of memory, 2.00 GiB per vCPU. In the name, "c" stands for compute, "8" is the generation, "id" marks Intel processors and local NVMe storage and "large" is the size within the c8id family. It runs on Intel Xeon Scalable (Granite Rapids) at 3.9 GHz, and AWS introduced it in February 2026. AWS has since shipped c9g; c9g.large is the direct replacement at this size. Rackspace Spot's ch.vs2.medium is a like-for-like substitute at 2 vCPU and 4 GiB, $0.111/hr on AWS in US East (N. Virginia), from $0.002/hr on Rackspace Spot.

Match qualityNo local disk

c8id.large comes with 1 × 118 GB NVMe SSD attached to the machine. Rackspace Spot nodes use network storage only, so that disk does not come with it.

If you were using the local disk as fast scratch space — temporary files, a local cache, an index — you will need a persistent volume or object storage instead, and both are slower to read. If it was just extra space you never depended on, nothing changes.

When to use it
Good for
  • ●Batch processing and CI/CD runners
  • ●Video encoding and transcoding
  • ●High-traffic web and API serving
  • ●Workloads that fit inside 4 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
  • ●The working set needs more than 4 GiB of RAM
  • ●GPU or FPGA acceleration is needed
  • ●Memory-hungry applications. A memory-optimized family gives more RAM per dollar.
  • ●More than 2.00 GiB of RAM per vCPU is needed — that ratio is fixed for the whole family
c8id.large runs $81/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.
