I wrote up [0] and [1] a while ago as an attempt to understand RSA and Diffie-Hellman. While not perfect and certainly far removed from any real-world implementation, I still revisit these to remind myself of the basics.

This is exactly where I began getting the most out of Vagrant, that is, simulating a distributed cluster locally. It gets me as close as possible to how it would work on the provider infrastructure, e.g. AWS. In particular, spinning up an automated Consul cluster and then using it get a group of RabbitMQ nodes to converge[0]. The same is certainly achievable through container orchestration, but that adds more layers of abstraction, especially on the networking side.
