The biggest “hidden” cost for me was Elastic Blockstore IO charges! It started adding up quite quickly and I realized I had to think twice about doing IO intensive calculations on EC2! I switched over to lightsail (obviously these are for personal projects).

Just use gp3, shouldn't be needed to request higher IO with it (except for DBs, probably cheaper to use DynamoDB etc then).

Yeah, provisioned IOPS can add up quick. Never had justification to spend on them myself. If I need IO I use instances with attached storage, otherwise I purely use the GP SSDs.
