We began because of the converting regarding 12 characteristics from the monolith toward microservices, and you may our company is now around more forty microservices you to definitely we have separated regarding earlier monolith.
We performed the newest migration effortlessly within this a half dozen month schedule, while we wished to finish within the time kept into the all of our on-premise agreements. You will find plans to fundamentally circulate totally to help you a good microservices-established frameworks, but we’re taking they a stride at once.
