r6g.large

Analysis

The r6g.large is a memory optimized instance in the r6g series with 2 vCPUs and 16 GiB of memory on AWS Graviton2 (up to 2.5 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.

Running it in Mumbai instead of São Paulo saves $69.93 a month per instance: $0.0650/hour against $0.1608/hour, a 147% spread.

Nothing else with 2 vCPUs and similar memory is cheaper: among 44 current same-shape types it has the lowest on-demand price.

At $0.1008/hour on demand in US East (N. Virginia), about $73.58 a month, the r6g.large is one of the cheaper ways to buy memory optimized capacity: only 1% of the 385 current memory optimized types cost less per vCPU-hour than its $0.0504.

It is the cheapest of the 5 processor variants AWS sells at this size and generation. The r6id.large on Intel Xeon 8375C (Ice Lake) costs 50% more, and the r6a.large, the r6gd.large and the r6i.large also sit above it.

The newer r7g.large on AWS Graviton3 is 6.2% dearer at $0.1071/hour.

Reserving it for a year with no upfront payment cuts the Linux rate to $0.0635/hour, which beats on demand once it runs more than 63% of the time; three years brings it to $0.0435/hour, 57% below on demand.
