VMware's Wade Holmes (VCDX #15) just released a NSX micro-segmentation book in time for the RSA conference. In about 70 pages he focuses on day 1 concepts and considerations. This is incredibly valuable, since the majority of companies begin their NSX journey by first adopting micro-segmentation.
The PDF book is free, and if you were lucky to attend the conference, you may get in in print! See the blog post and PDF link below:
I will read this soon and provide a more in-depth commentary on the book; I am also planning a install series with more of a concept and mindset, and how to work with the networking/server/security teams overall.
