I tried to scan through the linked article (and OP) but couldn't quite figure out Troy's storage requirements. Are they really massive?
The sum of the GB figured shown in the OP doesn't even amount to 200GB AFAICT. But even if it's something like 10TB that's still not super expensive on many hosting providers.
The post wasn't relating to data but more this quote:
> It's costing me 2.6c per day to support 141M monthly queries of 517M records.
Also, you might be able to store 1TB of data on a spinning disk with no problem but can you run the amount of queries he needs? Will you be able to run them as fast as you need? How much RAM would you need? etc.
He has a writeup here on how he gets costs down in a big way: https://www.troyhunt.com/serverless-to-the-max-doing-big-thi...
