c7g instances — Compute optimized
Graviton3 compute-optimized instances for CPU-bound work: batch, encoding, HPC front-ends, high-throughput web tiers.
The c7g family sits in AWS's compute optimized tier and runs on AWS Graviton (arm64) silicon. It spans8 sizes, from c7g.2xlarge (8 vCPU / 16 GiB) up to c7g.xlarge (4 vCPU /8 GiB). Pricing scales roughly linearly with size, so the per-vCPU cost is similar across the family — pick the smallest size that fits your workload's memory and CPU headroom, then use a Savings Plan or Reserved Instance to cut the effective rate. Graviton families like this one usually deliver the best price/performance in their tier, provided your stack runs on arm64.
