r8gb.large

Analysis

The r8gb.large is a memory optimized instance in the r8gb series with 2 vCPUs and 16 GiB of memory on AWS Graviton4 (up to 2.8 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.

Within the same generation and size, the r8g.large on AWS Graviton4 costs $0.1178/hour, 35% less ($46.98 a month). The other variants are the r8i-flex.large at $0.1320, the r8i.large at $0.1389 and the r8gd.large at $0.1470.

Its price is almost flat across the 2 regions that offer it ($0.1822 to $0.1822/hour), so latency and data residency should decide where it runs. It is not offered in Ohio, Canada Central, São Paulo, Ireland, London, Frankfurt, Mumbai, Singapore, Sydney and Tokyo, so plan around that if you need a presence there.

On demand it costs $0.1822/hour in US East (N. Virginia), $133 a month if left running, which puts it mid-table for memory optimized types at the 64th percentile per vCPU ($0.0911 per vCPU-hour) and the 80th percentile per GiB ($0.0114 per GiB-hour).

Looking beyond its own line, 30 of 44 current types with 2 vCPUs and similar memory are cheaper. The cheapest of those is the r6g.large on AWS Graviton2 at $0.1008/hour.

It is size 2 of 10 in the r8gb series. Stepping up to the r8gb.xlarge gives 4 vCPUs and 32 GiB for $133 more a month. Dropping to the r8gb.medium saves $66.50 a month.
