How to split a monolith and legacy code via code-sketches

Legacy-code monoliths are one of these challenges which lead often to controversy discussions and questions like:

  • What are the pros and cons of getting rid of the code-base?
  • How to get rid of it, via a big-bang or splitting it step by step?
  • What are the efforts?

In this post I’d like to describe a way how to create the first code-sketch which could lead to an insight into the possibilities to tackle the beast step by step. Continue reading “How to split a monolith and legacy code via code-sketches”

Application and system sketching based on code templates

book-731199_1280On almost every desk on this planet lies a pen and a piece of paper for notes. In the programmers or software-architects world notes are especially technical notes about a component or system – drawn e.g. as UML-sketches on a paper or via an UML tool. However a few minutes and discussions later the names of the UML-boxes are typed into an IDE as part of source-code that will be written during the next days, weeks, months… Continue reading “Application and system sketching based on code templates”

SOLID Sketching

Writing code to sketch the first core feature of an application could lead to a point where the next feature has to be realized roughly, too – just because of trivial dependencies. The code-base grows and when you are unlucky the overview of the sketches gets lost. However keeping the code-base clean and open for the future has to be a goal and can be achieved by applying the SOLID principles. Continue reading “SOLID Sketching”
