Analysis
The i4i.16xlarge is a storage optimized instance in the i4i series with 64 vCPUs and 512 GiB of memory on Intel Xeon 8375C (Ice Lake) (up to 3.5 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Within the same generation and size, the i4g.16xlarge on AWS Graviton2 costs $4.94/hour, 10.0% less ($401 a month), though switching means rebuilding software for arm64.
Running it in N. Virginia instead of São Paulo saves $2,390 a month per instance: $5.49/hour against $8.77/hour, a 60% spread.
At $5.49/hour on demand in US East (N. Virginia), about $4,008 a month, the i4i.16xlarge is one of the cheaper ways to buy storage optimized capacity: only 22% of the 90 current storage optimized types cost less per vCPU-hour than its $0.0858.
Looking beyond its own line, 27 of 39 current types with 64 vCPUs and similar memory are cheaper. The cheapest of those is the r6g.16xlarge on AWS Graviton2 at $3.23/hour.
It has local instance storage (4 x 3750 GB NVMe SSD), which is fast but lost when the instance stops. Network: 35000 Megabit.
It is size 7 of 9 in the i4i series. Stepping up to the i4i.24xlarge gives 96 vCPUs and 768 GiB for $2,004 more a month. Dropping to the i4i.12xlarge saves $1,002 a month.
