Build a Cloud in Thirteen Years
summary
A team builds Ubicloud in Ruby as a full control plane (VMs, load balancers, databases, console) and it works in production: ~20k lines of app plus tests, monthly gem releases, and a history of monthly releases that rarely regress. Key libraries are SQL, Roa, and Rodo. Surprising metrics include ~1,200 closed issues over 14 years with zero open ones and 100% branch coverage on core libs; deployment practice is deploy every PR so changes hit prod immediately.
