- we usually have redis, and it makes our stack simpler and easier to debug.

 repositories from external location etc. Using workers on instance that has
 the direct access to disks used by NFS as well as email server gives noticeable
 performance boost. Running local workers to the NFS storage results in faster
 execution of forking large repositories or sending lots of emails.
 
 Those instances need to be configured in the same way as for other nodes.
