yeah I run a vps too, multiple domains but I do like that functions as a service approach.
I unfortunately started with GoDaddy haha hilarious, overpriced that economy $1 thing garbage.
Just my opinions but yeah... had some caching problems too wouldn't replace the content ahhhhh. Saying it was my fault "flush dns" I'm testing with Tor externally in other countries. Also I'm using Ubuntu no flushing required I don't know.
Edit: moving up to t2.medium was because I implemented defuse/php-encryption and it took a toll encrypting decrypting, didn't help I had a dumb mistake where the cloning of data was stacking and not deleting so it was getting longer and longer... I know can use a better language but PHP is what I know at this time. I was able to drop back down to a t2.small but damn MySQL man... uses so much resources... with 2GB RAM it's idling like at 1.4GB or something... it just grows. I know you can tweak the settings. It's built on WordPress, I'm suggesting to strip the function of the site out of WordPress but future improvement.
Edit: not crapping on WordPress the plugins/dynamic aspect is cool and if I thoroughly understood it my shit wouldn't be so janky. I interfaced with an Evernote Sync plugin and was surprised the comments were in chinese haha but it's PHP so I could read the code.
Using memcache(d) was cool, yeah it was a cool job all in all.
Edit: You know what's hilarious is HIPAA compliant servers DAMN! That's expensive, I clearly was not using HIPAA servers as those were $300 - $600/mo at least. But not just that but the architecture of the site, I clearly expressed that I am not a security expert. But AWS goes over a bit on the design of separating interface with the storage of data. At least we've got zero-knowledge design of everything encrypted... that's kind of a problem in a way too, when the key-obj to encrypt is not known and you've got strings that you can't decrypt and you start getting "failed to decrypt" error messages like "oh shit..." I think that was just an initial config though hopefully.
Had a recent never-ending loop problem wow... you can watch the server spike to 100% CPU usage in HTOP and you're like "ah crap something's wrong"
