This article continues the analysis I started in my previous article, DAG: beyond the “A”.
We all understand that a good technology solution must have high levels of availability, and that simplicity and redundancyare the two major factors that drive solution availability. More specifically:
- The simpler the solution (the fewer independent critical components it has), the higher the availability of the solution;
- The more redundant the solution (the more of multiple, identical components that duplicate each other and provide redundant functionality), the higher the availability of solution.
