Put your API on a JSON diet

Last week I discussed design considerations for APIs, given that APIs aren't applications and shouldn't be treated as such. At small scales, APIs that come along for the ride with bulky Web frameworks might be fine, but beyond that you're asking for trouble. If you're building an API that will serve a large number of clients, your API code should be thin and tight, as well as make liberal use of caching. Otherwise, the future headaches will be crippling.

First look: VMware vSphere 6 keeps its edge

In the not so distant past, VMware held a long and commanding lead in the server virtualization space, offering core features that were simply unmatched by the competition. In the past few years, however, competition in virtualization has been fierce, the competitors have drawn near, and VMware has been left with fewer ways to distinguish itself.

This article will help you do just that. 

Docker 1.0 is ready for prime time

If you're on the lookout for an easier way to migrate apps and services from development to production, or from one server environment to another, then you may already be aware of Docker. The Linux container solution has made waves for a while now, even as it has been widely viewed as not quite ready for production. The Docker team has been working steadily at finalizing a release that it considers to be production ready, and it appears to have reached that goal with the introduction of Docker 1.0.

Puppet vs. Chef vs. Ansible vs. Salt

The proliferation of virtualization coupled with the increasing power of industry-standard servers and the availability of cloud computing has led to a significant uptick in the number of servers that need to be managed within and without an organization. Where we once made do with racks of physical servers that we could access in the data center down the hall, we now have to manage many more servers that could be spread all over the globe.
