Analysis
The i8ge.18xlarge is a storage optimized instance in the i8ge series with 72 vCPUs and 576 GiB of memory on AWS Graviton4 (up to 2.7 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Nothing else with 72 vCPUs and similar memory is cheaper: among 2 current same-shape types it has the lowest on-demand price.
Running it in N. Virginia instead of Sydney saves $1,242 a month per instance: $8.54/hour against $10.24/hour, a 20% spread. It is not offered in São Paulo, so plan around that if you need a presence there.
On demand it costs $8.54/hour in US East (N. Virginia), $6,236 a month if left running, which puts it mid-table for storage optimized types at the 66th percentile per vCPU ($0.1187 per vCPU-hour) and the 59th percentile per GiB ($0.0148 per GiB-hour).
It has local instance storage (6 x 7500 GB NVMe SSD), which is fast but lost when the instance stops. Network: 112.5 Gigabit.
It is size 7 of 9 in the i8ge series. Stepping up to the i8ge.24xlarge gives 96 vCPUs and 768 GiB for $2,079 more a month. Dropping to the i8ge.12xlarge saves $2,079 a month.
