Deploying Cloud Infrastructure at the Speed of the Cloud

In order to deploy new infrastructure at the speed their end users demand, IT needs visual automation tools with building-block architecture and true DIY capabilities.

Two of the chief values for the cloud are speed and agility. Cloud orchestration and automation tools promise to allow IT organizations to move significantly faster and become more competitive as service organizations. While orchestration tools typically do a great job of deploying applications flexibly once virtualization is in place, the underlying (or horrors—the non-virtualized and legacy) infrastructure is not very agile or automated. People are not addressing this head on. Instead, a lot of hand waving has been done at physical infrastructure issues, and it's the Achilles' heel of IT when trying to get agile. However, it doesn't have to be this way.

Why Infrastructure Agility Matters

Enterprise IT is under pressure from many sides—mandates, budget, user expectations and competitive gaps.

First of all, it's a truism that enterprise IT's mandate is shifting aggressively toward supporting innovation agility. However, budgets are not increasing to help IT meet this mandate. According to survey results from Gartner's 2014 CIO Agenda Report, global CIOs report a cumulative IT budget increase of only 0.2 percent in in 2014.

The reason may be another point of pressure—users' consumerized expectations of IT are making them go elsewhere. The same Gartner report has CIOs' reporting that 25% percent of IT spending is happening outside of the IT budget—and that's only what they can see. In other words, enterprise IT organizations are losing "market share" to public cloud offerings.

This shift may be explained by the competitive gap between the near instantaneous availability of public cloud resources and the relatively slow delivery available from traditional IT processes. According to Enterprise Management Associates' (EMA) 2014 Software Defined Data Center study, 47 percent of enterprises self-report taking anywhere from a week to over a month to deploy infrastructure for application developers and testers.

Compared to the "minutes" it takes to get access to public cloud resources, this is a significant competitive gap. Of course, not everything will shift to public clouds anytime soon. There will be plenty of infrastructure business for IT to handle well into the future, but it's in the best interest of IT groups to raise their game.

Physical Infrastructure is Still a Major Obstacle to Cloud Agility

Two of the chief tenets of the cloud and accompanying cloud automation are that all infrastructure becomes virtualized and has an automation-friendly, preferably REST-style API. This is certainly a helpful and simplifying vision. It makes it possible to turn "infrastructure into code" because everything is abstracted, software-defined and programmable.

The chief aspirational examples for this vision are webscale companies like Netflix that operate their businesses based on public cloud infrastructure from the likes of Amazon Web Services (AWS). Unfortunately, for most enterprise organizations that don't have the luxuries of youth and seemingly unlimited IT budgets that webscale businesses do, IT infrastructure reality can be quite a bit messier. According to a 2013 NTT Communications study, 58 percent of CIOs expressed that one of the biggest obstacles to cloud adoption was the complexity of their existing systems. Any IT organization that has been in existence for more than 10 years has legacy infrastructure that isn't virtualized and is probably not going to disappear anytime soon.

The physical realities of infrastructure have an impact on cloud-like agility for IT in a couple of different ways:

  • Day-zero deployment. Most enterprise IT infrastructure investments are still going toward private clouds today, and there is a sea change underway in how IT teams purchase infrastructure equipment. The old way is to buy best-of-breed solutions in each category—compute, networking, storage and virtualization, then integrate these pieces themselves. Increasingly, there is a move toward converged infrastructure products like VCE Vblock, reference architectures like EMC VSPEX and even hyper-converged solutions like Nutanix or the recently announced VMWare EVO:RAIL. The advantages of converged infrastructure, reference architecture and hyper-converged solutions include that they come integrated, tested and certified as interoperable and able to reach certain performance benchmarks, or support a certain number of virtual machines or desktops. This relieves the enterprise IT team of having to act as the systems integrator. However, even with integrated products, the day-zero provisioning work to stand up a data center pod based on these products and architectures is anything but trivial. Typically, it involves multiple domain experts working together to manually configure them for a particular deployment use case. It often takes anywhere from one to three weeks. This would be fine if it weren't such a wasteful use of talent and if such long provisioning and deployment timeframes weren't so painfully out of step with the offerings from public cloud providers, where you can spin up VMs in minutes.
  • Supply chain. Remembering the competitive gap versus public cloud providers in terms of time to deploy, it's relevant to note that the deployment of private cloud infrastructure has a real supply chain dynamic. Most datacenter infrastructure is bought through distribution and systems integration channels today. The reason this is of interest is that even if we assume that distributors maintain ample stocks of inventory (in a just-in-time logistics world) so that there's never a lag time due to shipment from the equipment manufacturers, typically the distributor or the systems integrator has to perform some level of provisioning. Let's also remember that the IT products distribution business operates on relatively thin margins. So while manufacturers with much thicker margins have lots of highly specialized folks; the distribution channel has less. This means that if provisioning takes experts sitting in a room for three weeks, there are less of them to go around. The supply chain then becomes a constraint for IT enterprise groups to even receive the infrastructure in a timely way. If enterprise IT is threatened competitively by the responsiveness of public cloud/shadow IT, then the supply chain is also threatened.
  • Infrastructure as a Service. When building a private or hybrid cloud IaaS offering, many IT groups are challenged by the fact that they must deal with physical infrastructure assets such as non-virtualized/dedicated servers, networking switches and legacy, non-virtualized storage arrays. The presence of these assets is absolutely non-trivial. For example, the EMA SDDC study found that 83 percent of IT organizations are running applications on dedicated servers. In addition, while Software Defined Networking (SDN) is at the peak of its hype cycle, the fact is that it barely exists in deployment, especially in enterprise IT environments. In fact, an August 2014 poll found that two-thirds of respondents pegged SDN as being at least three to five years away. As a result, IaaS that can't address both virtualized and non-virtualized infrastructure can become yet another silo that doesn't help move the whole business forward.
