In my previous gig (2017 timeframe), we moved from AWS instances with terraform plus chef which took a couple hours of focused engineer time to generate a new dev environment. This was after some degree of automation, but there were still a great deal of steps one had to get through and if you wanted to automate all that how would you glue it all together? Bash scripts?

We transition to k8s, with PG and other data stores in cluster, specifically RabbitMQ, and Mongo, which runs surprisingly well in k8s. In any case, after the whole adoption period and a great deal of automation work against the k8s APIs, we were able to get new dev environment provisioning down to 90 seconds.

There was clearly some pent up demand for development resources as we went from a few dev environments to roughly 30 in one month's time.

Following that, the team added the ability to "clone" any environment including production ones, that is, the whole data set and configuration was replicated into a new environment. One could also replicate data streaming into this new environment, essentially having an identical instance of a production service with incoming data.

This was a huge benefit for development and testing and further drove demand for environments. If a customer had a bug or an issue, a developer could fire up a new environment with a fix branch, test the fix on the same data and config, and then commit that back to master making its way into production.

These are the benefits of running data stores governed by one's primary orchestration framework. Sounds less threatening when put that way, eh?
