$900/month – whether thats too little or too much entirely depends on the company's revenue/margins. I've seen companies that do not care about AWS spend. It makes close to zero difference to them and just thinking about the cost costs more. On the other spectrum, I've seen companies that move to bare metal servers. A couple of servers and that's all they need. $120/month from $2000/month and it mattered to them.

So yeah, what you're saying is sort of meaningless without understanding the business type/stage/revenue/costs.
