As we saw in the previous post, software architecture is all about decoupling different parts of your system through boundaries. This post presents some ideas for actually creating these boundaries.

This post covers some general ideas on software architecture, with a specific focus on the boundaries between different parts of the system.

The SOLID principles are five software design principles that aim to make the code more clear, offer more flexibility and help with maintainability. Although they were originally aimed at object-oriented design, more specifically the design of classes, the general ideas behind most of them are universal and can also be applied to other paradigms like functional programming.

Sometimes, the best thing you can do for your code is to stop thinking about it - at least consciously.

Branch By Abstraction is a development technique that allows teams to make large changes while collaborating in a single branch and without breaking the system while the change is in progress. It is an alternative to long-lived feature branches. This post will also talk about application strangulation, which is a similar technique that works at a higher level.
