Having a backyard full of trees is quite therapeutic during a marathon day of conference calls, but it also comes with a fair share of maintenance: picking up the fallen limbs from the elms, keeping the invasive cedars from choking out other species, and trimming up the oaks to keep them healthy and the fireplace burning through the winter. On those maintenance days, it’s easy to get obsessed with a tree or set of trees that are causing a problem … say, dropping large limbs dangerously close to your daughters’ trampoline. When you’re fixing up your backyard, one problem – one tree – at a time, the solution to the problem at hand often fails to take into account the needs of the larger ecosystem. Unfortunately, for many networking professionals, every day feels like a maintenance day.
We see problems with mobility and service chaining in and across data centers. We see problems with cost and reliability in the WAN. We see problems with scalability and security in the campus. In a nutshell, we see problems. Fortunately, for every problem, there’s a good ol’ fashioned snake oil salesman. We’re inundated with the latest and greatest technologies to solve our woes … even some we didn’t know we had.
The problem is that we’re putting Band-Aids on bullet holes. The bleeding stops, but the real problem is still lurking beneath the surface. It’s not that these fixes are bad. The problem is that they’re being positioned as a cure-all instead of simply tools to address localized side effects of the problem.
The problem is broader. The data center exists to host applications. Those applications exist to enable users. The WAN exists to connect the data center to the campus, which exists for the users. And, of course, the users exist to run the business.
Since the business is the thing we’re looking to keep alive and thriving, those users need to be productive. That means that they need fast, efficient access to the applications that enable their jobs. So, those problems we rattled off earlier are really just symptoms that have emerged as we tried to create enterprise services across silos of control.
If we want to remove the bullet and save the patient, we must recognize the need for end-to-end services and look holistically at Enterprise Virtualization methods that will securely extend services from user to application at scale with on-demand mobility and business continuity. Otherwise, the problem is only going to get worse.
With the Internet of Things (IoT) becoming an ever-increasing reality in the enterprise, the need for services from device to application is going to multiply exponentially. Without Enterprise Virtualization, the burden on IT to deal with every little problem across the islands of campus, WAN and data center will be overwhelming. They simply won’t be able to keep pace, and, as a result, neither will the business. The users will be limited and become frustrated, and productivity will suffer in turn. It’s a bleak picture, but it doesn’t have to be.
Enterprise Virtualization provides a number of advantages that have long been unattainable to the general enterprise. While we’ve managed to achieve “micro-segmentation” down to the virtual machine layer for applications, the very same data is set free at the data center doors and left vulnerable in the less secure world beyond.
Enterprise Virtualization enables you to extend the segmentation in the data center to the very edges of the network, where the data is consumed by users. Not only can you extend isolation, you can also view it as one contiguous service from server node to user node.
All of the tools available for measuring quality and performance have a clear view from end-to-end, rather than requiring additional tools to aggregate and correlate metrics across the three different islands of technology. Not to mention, Enterprise Virtualization allows you to significantly reduce the number of touch points while provisioning and troubleshooting, thus minimizing the likelihood of down time due to human error.
Just like that limb-dropping elm can avoid the chainsaw, your enterprise can avoid being cut down in its prime. You see, it was a problem in the ecosystem that would have eventually killed all the trees through their intertwined root systems. It was lurking beneath the surface, but the arborist took a step back to see the whole forest, and then recognized and treated the real issue. Likewise, you need to make sure that someone is looking at your forest of IT challenges … not just banging their head on a single tree.
