The building blocks of multi-tenancy are Linux namespaces , the very technology that makes LXC, Docker, and other kinds of containers possible. For example, the PID namespace makes it so that a process can only see PIDs in its own namespace, and therefore cannot send kill signals to random processes on the host. User Namespaces.

This gets even more tricky when those integrations are over on-prem-only technologies, like MSMQ, that don’t integrate out-of-the-box with cloud alternatives like Azure Service Bus or Amazon SQS. Technically, this is all done over MSMQ where requests are processed and eventually granted or rejected, notifying other services of the outcome.
