The way backWe had one production environment with multiple serversOne beta server with all components with versions matchingcurrent production as a hot�x environmentOne beta server clone for next release, we can call it “staging”One integrations server that never worked

The way backTen production componentsCon�gurations for all services were kept in Git repo in separatedirectories for di�erent environments and componentsCon�gurations were changed manually and merged from onerelease to another

The way backBunraku was on worker instances and Skynet system utilizedBunraku on static server infrastructureNobody knew how to manually con�gure and bring up newenvironment, whether it is a production, development or betaWe knew all build dependencies for all components, but not theruntime
