Working with containers, one concept that seems to always confuse developers and administrators is layers. Despite the elegance and simplicity of the design, they are still a black box to most teams. In this post, I’ll explain how they work conceptually and the basis of their implementation.

In many cases, they started with the wrong one. This post will explain the difference.
