The Journey of a Request to the Backend
Manage episode 372764617 series 1954062
From the frontend through the kernel to the backend process
When we send a request to a backend most of us focus on the processing aspect of the request which is really just the last step.
There is so much more happening before a request is ready to be processed, most of this step happens in the Kernel. I break this into 6 steps, each step can theoretically be executed by a dedicated thread or process. Pretty much all backends, web servers, proxies, frameworks and even databases have to do all these steps and they all do choose to do it differently.
