What is a rainbow deployment? It is an extension of blue/green where instead there are several colors (rainbow). Rainbow deployment allows you to pinpoint versions to customer/reseller groups making it possible to release minimizing impact. Testing a new release can now target less sensitive customers first, and then slowly, include the rest of the customer base. At Clover we implemented a solution for Rainbow Deployments using Nomad and NGNIX to deploy our monolith COS (Clover OS).
