Redis in-memory database

• Use for queuing with Bull

We use a managed redis database on Digital Ocean as a queueing service. This is used to ensure we can scale out our workers across multiple hosts. Workers will pick up any available job on the queue.

Why use redis / bull for queing

• It has a nice dashboard (bull board)
• I've used it before previously and it works and has nice features
• Lots of people use redis for queuing
