Analysis
The m7i-flex.4xlarge is a general purpose instance in the m7i-flex series with 16 vCPUs and 64 GiB of memory on Intel Xeon Scalable (Sapphire Rapids) (up to 3.5 GHz), which makes it balanced at 4 GiB of memory per vCPU.
Within the same generation and size, the m7g.4xlarge on AWS Graviton3 costs $0.6528/hour, 15% less ($82.69 a month), though switching means rebuilding software for arm64. The other variants are the m7i.4xlarge at $0.8064, the m7gd.4xlarge at $0.8543 and the m7a.4xlarge at $0.9274.
Running it in N. Virginia instead of São Paulo saves $332 a month per instance: $0.7661/hour against $1.22/hour, a 59% spread.
At $0.7661/hour on demand in US East (N. Virginia), about $559 a month, the m7i-flex.4xlarge is one of the cheaper ways to buy general purpose capacity: only 25% of the 354 current general purpose types cost less per vCPU-hour than its $0.0479.
Reserving it for a year with no upfront payment cuts the Linux rate to $0.5067/hour, which beats on demand once it runs more than 66% of the time; three years brings it to $0.3475/hour, 55% below on demand. Windows Server roughly doubles the bill at $1.47/hour, because the licence is charged per vCPU.
The newer m8i-flex.4xlarge on Intel Xeon Scalable (Granite Rapids) is 5.0% dearer at $0.8044/hour.
