How We Saved $132k a Year With an IT Infrastructure Audit
I will add another suggestion, if you use S3 at all... one of your largest costs is likely the bandwidth. Have you considered just placing caches in front?I took a $100 per month S3 bill down to $5 per month by simply having existing Nginx servers enable a file cache.It does help that I never need to cache purge (versions are saved in S3 and become URLs), but it was super trivial to just wipe out $95 per month of cost for zero extra spend.My current setup is:S3 contains user photos, web app (not on AWS) handles POST/GET for S3 (and storing local knowledge), Nginx at my edge has a cache that is currently around 28GB of files, and then CloudFlare in front of all of this saves me around 2TB of bandwidth per month.The real gotcha for me is that I was relying on CDNs for my cache, but when CDNs reach 50+ PoPs I was starting to see multiple requests for the same thing as a result of people in different cities requesting a file. So the Nginx cache I've added mostly deals with this scenario and prevents additional S3 cost being incurred.
