I released “VMS ARE DEAD” this post two weeks ago on DevOps.com.  My point here is that Ops Automation (aka DevOps) is FINALLY growing beyond Cloud APIs and VMs.  This creates a much richer ecosystem of deployment targets instead of having to shoehorn every workload into the same platform.

In 2010, it looked as if visualization had won. We expected all servers to virtualize workloads and the primary question was which cloud infrastructure manager would dominate. Now in 2015, the picture is not as clear. I’m seeing a trend that threatens the “virtualize all things” battle cry.

Really, it’s two intersecting trends: metal is getting cheaper and easier while container orchestration is advancing on rockets. If metal can truck around the heavy stable workloads while containers zip around like sports cars, that leaves VMs as a strange hybrid in the middle.

What’s the middle? It’s the El Camino, that notorious discontinued half car, half pick-up truck.

The explosion of interest in containerized workloads (I know, they’ve been around for a long time but Docker made them sexy somehow) has been creating secondary wave of container orchestration. Five years ago, I called that Platform as a Service (PaaS) but this new generation looks more like a CI/CD pipeline plus DevOps platform than our original PaaS concepts. These emerging pipelines obfuscate the operational environment differently than virtualized infrastructure (let’s call it IaaS). The platforms do not care about servers or application tiers, their semantic is about connecting services together. It’s a different deployment paradigm that’s more about SOA than resource reservation.

On the other side, we’ve been working hard to make physical ops more automated using the same DevOps tool chains. To complicate matters, the physics of silicon has meant that we’ve gone from scale up to scale out. Modern applications are so massive that they are going to exceed any single system so economics drives us to lots and lots of small, inexpensive servers. If you factor in the operational complexity and cost of hypervisors/clouds, an small actual dedicated server is a cost-effective substitute for a comparable virtual machine.

I’ll repeat that: a small dedicated server is a cost-effective substitute for a comparable virtual machine.

I am not speaking against virtualize servers or clouds. They have a critical role in data center operations; however, I hear from operators who are rethinking the idea that all servers will be virtualized and moving towards a more heterogeneous view of their data center. Once where they have a fleet of trucks, sports cars and El Caminos.

Of course, I’d be disingenuous if I neglected to point out that trucks are used to transport cars too. At some point, everything is metal.
