Description
We are entering an era in software engineering where we rely on libraries and frameworks to do most of our work. While this is useful and save tremendous dev hours, it creates leaky abstractions that manifest in the form of performance degradation, unexpected errors, 100% CPU, network and disk usage, hangs, latency, and many other. It becomes difficult to articulate what goes wrong on the Backend and how to fix it when engineers don’t understand the basic building block of what they are interacting with.Network communication is one of the most critical pieces in backend engineering. And the TCP/IP Internet suite is the basic fundamental building block of communications that links the front end to the Backend. These layers are essential for backend engineers to optimize the stack, minimize latency, and increase throughput.
