One of the things I forgot to talk about in my last posting was the use of MessagePack. MessagePack is a library that lets you take objects and convert them into something much smaller than JSON. Some people have reported using MessagePack and have saved up to 50% of space over JSON. That’s not a bad saving for just using a library. In my example, I wasn’t dealing with any objects that was too complex but there is still a benefit of using MessagePack.

One of the things I find myself always looking into and being excited about is scaling out systems. Now this means different things to different people. The reason for me looking into RPC is how to deal with Microservices as part of a way to move Monolithic applications to into the Microservices architecture. RPC (or Remote procedure call) is an idea that has been in computer science for a bit now.
