I was unaware that Amazon even sold single AZ S3. 20% discount. Doesn't seem worth it. By the time I commit to purchasing S3 space, it has to be important data.

I get that S3 is convenient and reasonably performant, but it is not cheap at all.

That’s simply not true. I use S3 (well GCS mostly) for data that I wouldn’t be upset if it’s lost. And I pay the zonal discount for it.

Yeah agreed - any ephemeral stuff I need is generally in DynamoDB - S3 (and database) are for permanent storage.

Single AZ S3 has other benefits. The point isn't the price, it's that it's _highly performant_ since you can keep all of your reads in the same AZ

It's a great service for large caches. For example, we process a lot of imagery that we download from third-party providers. We save a lot of latency by storing the data in a single-AZ S3.

If it dies, we will just have to re-download the data.
