Linux Containers have become increasingly important over the last few years, in particular driven by Cloud applications. But what are containers, and how can they be useful?

This is an expanded, English-language version of a presentation I had to prepare during my studies. As such there are likely to be some misunderstandings. I am looking forward to be contacted with corrections.

This is a fairly low-level view at container concepts, and not a tutorial for a specific technology like Docker.

Code Comprehension Tools make it easier to understand and explore existing code bases by providing overviews, cross-references, and visualisations. They assist software engineers during software maintenance, in contrast to tools that help during initial development.
