Mad about microsegmentation
The tech industry seems fixated breaking things apart into ever-smaller units for greater levels of "granularity." Traditional standalone applications are maligned as "monoliths" that must be broken apart in to their component pieces, or "microservices." Broad brush security that covers an entire network is deemed insufficient, to be replaced by "microsegementation" -- applying security policies on a per-workload basis.
But breaking up is hard to do. In his story, "Mad About Microsegmentation," senior technology editor Stephen Bigelow lays out the pitfalls that will befall operators as they go down this road.

With the hype around converged and hyper-converged IT infrastructure, resistance seems futile. While your IT organization will likely be a mix of converged, dedicated and cloud-based resources, convergence is moving into new areas.
It's time for IT to get over the past and embrace the future. And yes, this is going to affect your applications. Ask yourself: Why aren't we using software as a service?
