The practice of microsegmentation takes the principles of least privilege to their logical conclusion by atomizing the isolating techniques of network segmentation. Security architects use microsegmentation to create security boundaries that can extend all the way into individual workloads by controlling East-West, or server-to-server, traffic flows between applications. The bulkheads put up through microsegmentation make it possible to better limit lateral movement of attackers, even in a cloudy world with no perimeter.

But the practice can be tricky to get right, and many experts warn that the journey to effective microsegmentation is fraught with pitfalls. Here are a few suggestions about how to avoid the mistakes en route to effective microsegmentation.

Micro-segmentation is scary
From my experience the truth is that simple segmentation and zoning is very hard in todays environments - people are struggling to separate PROD from DEV in anything but non trivial environments. let alone doing smth that is even close to micro.
The biggest mistake that people make, imho, is that they try to move from 0 to 100 and the comlexity vs. the marginal benefit over a much more modest segmentation goals is what kills the project, unfortunatelly for many years in an organization, once they fail it will take them a long time to try again. And frankly for most organizations it seams so "unachievable" that they do not even start doing it. 
My recommendation is to define modest goals such as separate prod from dev and select ~10-20 of you most cirital apps to ring-fence this achievable especially if leveraging the modern micro-segmentation technologies and you will be in a much much better place from your risk perspective.
