At that time I had other books waiting on my bookshelf, but I was so impatient to read this one, that I admit I started immediately after the Phoenix Project. This one was the one that I wanted to read.

The contents in this book are well organised, and chapter after chapter it’s easy to accept the challenges that an organisation of this size had to conquer to become successful in managing the infrastructure, processes and people.

What I really mean.. is that we can’t always keep up with the pace of new technologies and just re-design things from ground up following new trends without understanding or maintaining the legacy design or more importantly meeting the business needs.

Starting from the network and I like to create a basic network diagram will outline at glance things that could potentially limit infrastructure growth or expose it to potential risk that we need to mitigate. Designing , re-designing things well or better is based on getting the requirements right and verify that desired targets are met. To speed up this discovery process we use tools to gather the information we need. Continue reading “Powershell: How to perform Ping Sweep and Reverse-Lookup on a private network”
