Analysis
The m8i-flex.xlarge is a general purpose instance in the m8i-flex series with 4 vCPUs and 16 GiB of memory on Intel Xeon Scalable (Granite Rapids) (up to 3.9 GHz), which makes it balanced at 4 GiB of memory per vCPU.
Within the same generation and size, the m8g.xlarge on AWS Graviton4 costs $0.1795/hour, 11% less ($15.75 a month), though switching means rebuilding software for arm64. The other variants are the m8i.xlarge at $0.2117, the m8gd.xlarge at $0.2306 and the m8a.xlarge at $0.2434.
Running it in N. Virginia instead of São Paulo saves $87.16 a month per instance: $0.2011/hour against $0.3205/hour, a 59% spread.
On demand it costs $0.2011/hour in US East (N. Virginia), $147 a month if left running, which puts it mid-table for general purpose types at the 36th percentile per vCPU ($0.0503 per vCPU-hour) and the 36th percentile per GiB ($0.0126 per GiB-hour).
Compared with the previous generation, it costs 5.0% more than the m7i-flex.xlarge on Intel Xeon Scalable (Sapphire Rapids) ($6.99 more a month per instance), in exchange for the newer processor.
Looking beyond its own line, 15 of 42 current types with 4 vCPUs and similar memory are cheaper. The cheapest of those is the t4g.xlarge on AWS Graviton2 at $0.1344/hour. It is burstable, so it only suits workloads that do not run the CPU flat out.
