t4g.micro

Analysis

The t4g.micro is a general purpose instance in the t4g series with 2 vCPUs and 1 GiB of memory on AWS Graviton2 (up to 2.5 GHz), which makes it very compute-heavy at 0.5 GiB of memory per vCPU.

Running it in Mumbai instead of São Paulo saves $5.69 a month per instance: $0.00560/hour against $0.0134/hour, a 139% spread.

Nothing else with 2 vCPUs and similar memory is cheaper: among 4 current same-shape types it has the lowest on-demand price.

At $0.00840/hour on demand in US East (N. Virginia), about $6.13 a month, the t4g.micro is one of the cheaper ways to buy general purpose capacity: only 1% of the 354 current general purpose types cost less per vCPU-hour than its $0.00420.

It is size 2 of 7 in the t4g series. Stepping up to the t4g.small gives 2 vCPUs and 2 GiB for $6.13 more a month. Dropping to the t4g.nano saves $3.07 a month. Unit price is not flat across the series ($0.00210 to $0.0336 per vCPU-hour), so the size changes the rate you pay.

Reserving it for a year with no upfront payment cuts the Linux rate to $0.00530/hour, which beats on demand once it runs more than 63% of the time; three years brings it to $0.00360/hour, 57% below on demand.
