Five VM-Level Infrastructure Adaptations — Virtualization Review

An IT industry analyst article published by Virtualization Review.

Infrastructure is evolving for the better, making the job of the admin easier in the long run. Here are five ways it’s evolving to work at the VM level.

article_adaptations-of-the-infrastructureIt used to be that IT struggled to intimately understand every app in order to provide the right supporting infrastructure. Today, server virtualization makes the job much easier, because IT can now just cater to VMs. By working and communicating at the VM level, both app owners and infrastructure admins stay focused, using a common API to help ensure apps are hosted effectively and IT runs efficiently.

But the virtual admin still has to translate what each VM requires, going beyond direct-server resources into the specialized domains of other IT infrastructure silos. While silos have traditionally pooled rare expertise to optimize expensive resources, in today’s virtualized world, silos seem to offer more friction than leverage. Here are five ways infrastructure is evolving to work at the VM level.

‘Software-defined’ to define data center of the future

An IT industry analyst article published by SearchDataCenter.

Software-defined means many — sometimes conflicting — things to many people. At the core, it means letting the application control its resources.

Is there a real answer for how “software” can define “data center” underneath the software-defined hype?

Vendors bombard IT pros with the claim that whatever they are selling is a “software-defined solution.” Each of these solutions claims to actually define what “software-defined” means in whatever category that vendor serves. It’s all very clever individually, but doesn’t make much sense collectively.

We suffered through something similar with cloud washing, in which every bit of IT magically became critical for every cloud adoption journey. But at least in all that cloudiness, there was some truth. We all at least think we know what cloud means. The future cloud is likely a hybrid in which most IT solutions still play a role. But this rush to claim the software-defined high ground is turning increasingly bizarre. Even though VMware seems to be leading the pack with their Software-Defined Data Center (SDDC) concept, no one seems to agree on what software-defined actually means. The term is in danger of becoming meaningless.

Before the phrase gets discredited completely, let’s look at what it could mean, as with software-defined networking (SDN). In the networking space, the fundamental shift that SDN brought was to enable IT to dynamically and programmatically define and shape not only logical network layers, but also to manipulate the underlying physical network by remote controlling switches (and other components).

Once infrastructure becomes remotely programmable, essentially definable through software, it creates a new dynamic agility. No longer do networking changes bring whole systems to a grinding halt, manually moving cables and reconfiguring switches and host bus adapters one by one. Instead of an all-hands-on-deck-over-the-weekend effort to migrate from static state A to static state B, SDN enables networks to be effectively redefined remotely, on the fly.

This remote programmability brings third-party intelligence and optimization into the picture (a potential use for all that machine-generated big data you’re piling up)…
