m6g.xlarge

Analysis

The m6g.xlarge is a general purpose instance in the m6g series with 4 vCPUs and 16 GiB of memory on AWS Graviton2, which makes it balanced at 4 GiB of memory per vCPU.

Running it in Mumbai instead of São Paulo saves $105 a month per instance: $0.1012/hour against $0.2448/hour, a 142% spread.

At $0.1540/hour on demand in US East (N. Virginia), about $112 a month, the m6g.xlarge is one of the cheaper ways to buy general purpose capacity: only 9% of the 354 current general purpose types cost less per vCPU-hour than its $0.0385.

It is the cheapest of the 5 processor variants AWS sells at this size and generation. The m6id.xlarge on Intel Xeon 8375C (Ice Lake) costs 54% more, and the m6a.xlarge, the m6gd.xlarge and the m6i.xlarge also sit above it.

The newer m7g.xlarge on AWS Graviton3 is 6.0% dearer at $0.1632/hour.

Reserving it for a year with no upfront payment cuts the Linux rate to $0.0966/hour, which beats on demand once it runs more than 63% of the time; three years brings it to $0.0669/hour, 57% below on demand.

It is size 3 of 8 in the m6g series. Stepping up to the m6g.2xlarge gives 8 vCPUs and 32 GiB for $112 more a month. Dropping to the m6g.large saves $56.21 a month.
