Slack’s Migration to a Cellular Architecture
https://slack.engineering/slacks-migration-to-a-cellular-architecture/
"...we have migrated the most critical user-facing services at Slack from a monolithic to a cell-based architecture over the last 1.5 years. In this series of blog posts, we’ll discuss our reasons for embarking on this massive migration, illustrate the design of our cellular topology along with the engineering trade-offs we made along the way" -- #CooperBethea #slack
