The cost of building out our private setup was my time for about a month.

At the time we didn't have a choice, as nothing like Fargate existed, but today it's also easier to do setups like the one we did. It mostly involved rsyncing base images over, rsync and a super simple storage service for backups, a LDAP based directory service, and and a thin layer over vzctl (first) and docker when that became an option, coupled with a VPN setup to tie our locations together, and a reverse proxy setup that did dynamic lookups in our private DNS fed from LDAP.

It is hard to do as a multitenant public service, it's trivially easy to do as an internal tool that needs to support only exactly what you need.

I've built out setups like this for a number of clients since, and it's typically 1-3 months of work to automate pretty much everything depending on complexity, and so it pays for itself quickly from a very low scale.

The first company I did this at wouldn't have been profitable at all if we'd relied on AWS
