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.

Breaking with tradition is hard too. For decades, one of IT's primary responsibilities has been to protect its systems from catastrophic failure by performing regular point-in-time backups that can get back to a known good state.
