This is something I’ve been meaning to write for some time, since I see new tools and extensions added to System Center every day. Many of these extensions are powerful and free which many use in their day to day job. So therefore I decided to write down a list of those tools I know free or otherwise(cost money) for the System Center portofolia. This list shows the whole ecosystems around System Center and the possibilities it has! Im guessing that many here might be new to someone. Hopefully some of these tools are of use to you 
And if someone knows of an extension or tool that is not on the list please leave a comment and ill add it to the list ASAP.
