Re: Yawn...
Not even close. VMs exist mainly because software developers don’t have access to a stable platform to design against. As such, they set a bunch of requirements for all kinds of systems which traditionally required more servers... which required IT people to build from a list of requirements... who then virtualized them.
In a DevOps environment, there’s no need for VMs because the platform is probably fully distributed using technologies like Redis for example. Table stores are favored over traditional SQL servers. Object storage is available without the need for file servers. As such, we develop software towards a platform which is triggered by timers and HTTP servers.
When you don’t have DevOps, you have IT guys and generally absolute shitty platforms which are closer to super computers than business systems. When you have DevOps, you can dump shit like software defined data centers. You don’t need virtual machines or containers. You don’t care about x86 vs ARM.
So.... nope... not even close. DevOps is about a system wher developers and operators develop and operate business systems without the chaos and madness you would generally find with IT people involved.
We’re currently replacing about $20 million of data center equipment and about 150 IT people with some Raspberry PIs and a dozen programmers. All the crap that has to be VMs like AD, e-mail and collaboration is going cloud. All the business software will be developed in-house. We have done initial testing and have proven that security, agility and performance is substantially higher this way.
