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?<p>I took a $100 per month S3 bill down to $5 per month by simply having existing Nginx servers enable a file cache.<p>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.<p>My current setup is:<p>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.<p>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.
