Very little of what the large public cloud providers do is actually applicable to a private cloud. The reason for this is twofold: scale and application.

Boys and girls, today's homework assignment is a thought experiment. I want you all to put yourselves in the shoes of the CXO team making a decision to move to private cloud. There is, of course, one catch: You may not factor in ROI. We're dropping ROI because it clouds the subject (bad pun intended.) Let's skip the why-should-I-do-this-experiment; I'd of course default to,"Because I told you so."

A commonly overlooked component of a private cloud deployment is the service catalog. In many cases, a great deal of time is spent architecting and discussing infrastructure, virtualization and automation processes with little thought of the actual service delivery. Service catalogs are key to successful private cloud deployment and the overall usability of the services your cloud delivers.

Last week in a blog titled "BYOD--Bring Your Own Disaster," I urged caution and scope for BYOD projects. This week I'm playing devil's advocate with myself. A conversation with Greg Knieriemen got me thinking of the consequences of ignoring BYOD. Let's dive into the risk of burying your head in the sand and ignoring the BYOD push.

In keeping with the tradition of the last three to five years, 2012 is being touted by analysts and vendors alike as "the year for VDI." This year there is a slightly new twist to the hype and marketing, and that's Bring Your Own Device (BYOD). It's a simple concept: Employees own devices that they like to use and are most productive on; IT should support the apps and services used to run the business on the employees' devices.

One of the more hyped use-case examples for hybrid cloud is cloud bursting. And why not? It's truly the have-your-cake-and-eat-it-too scenario. During normal business operations, your systems run in-house on private cloud infrastructure, and during unforeseen or unpredictable peaks, your services burst to excess capacity at your public cloud provider(s) of choice. It's IT utopia, right? It’s the comfort of maintaining your own systems with the insurance of endless available capacity for the unknown.

One of the advantages of a private cloud architecture is the flexible pooling of resources that allows rapid change to match business demands. These resource pools adapt to the changing demands of existing services and allow for new services to be deployed rapidly. For these pools to maintain adequate performance, they must be designed to handle peak periods, and this will also result in periods with idle cycles.

In terms of performance and business agility, private cloud is the foreign import compared to your family sedan data center of today. And when you migrate to that cloud, if you bring along your old ways of thinking and siloed application development mindset, you’ll miss out on the benefits the platform provides. You need to ensure your services and applications are developed in a way that harnesses the full potential of the architecture.

Long ago, in a data center far, far away, we as an industry moved away from big iron and onto commodity hardware. That move brought with it many advantages, but it also brought higher hardware and operating system software failure rates. This change in application stability forced us to change our deployment model and build the siloed application environment: one application, one operating system, one server.

One of the key decisions in architecting an infrastructure for private cloud is selecting a storage platform for the deployment. Storage is a key component of the infrastructure and will play a major role in the overall performance of the private cloud. The storage decision carries additional weight due to its larger investment and typically longer refresh cycle.

In many data centers large and small there is a history of making short-term decisions that affect long-term design. These may be based on putting out immediate fires, such as rolling out a new application, expanding an old one or replacing failed hardware. They may also be made by short-sighted or near-sighted policies, or, more commonly, old policies that aren't questioned in light of new technology. These types of decisions can range from costly to crippling for data center operations.

Most private cloud discussions revolve around the ROI of the architecture. Many discussions begin and quickly end with ROI. The reason is that ROI is very difficult to show in real numbers for any IT investment, but more so when the majority of the costs are soft costs.

Private cloud architectures involve a tight coupling of software and hardware, layered with automation and orchestration. These environments can be prone to complexity, which leads to additional deployment time, administrative costs and risks. Removing as much complexity as possible will help ensure a smoother deployment and ongoing environment.

With Microsoft and Google both heavily utilizing containerized data centers for compute capacity, it’s hard not to think about the applicability for enterprise and government private clouds. While containers vary widely, the general concept is that they are a self-contained data center environment complete with network, compute and storage, as well as necessary cooling.

A great end goal for the cloud model is PaaS. PaaS breaks the 1-to-1 relationship between OS and application/service, and provides for more fluid scalability. Additionally, PaaS platforms can remove the requirement for custom OS and server builds on a per-service basis, further reducing administrative overhead.

When assessing an IT road map for the next three to five years, you’d be remiss to leave cloud options out of the process. The business agility and potential cost savings of an IT-as-a-service-focused cloud architecture can catapult a business ahead of its competition.

Making the decision to move forward with a private cloud doesn't mean you should rule out public cloud services--you can have your cake and eat it, too. The technical and business drivers that were used to decide on private cloud may not be applicable to every service and deployment model. In most cases, the greatest benefits will be found in a mixture of private and public cloud services.

Any migration to the cloud should have a focus on the services required and the best way to deliver those services. Business enablement should hold as much, or more, weight than ROI. The same holds true when discussing virtual desktops.

When designing a private cloud infrastructure as part of a next generation data center strategy, there are several options to choose from for a delivery model. In some cases, the IT service delivery will be some subset of true private cloud. In other cases, a full cloud model will be more appropriate, and delivery will typically be in an IaaS or PaaS model, with the possibility of a mixed model.

Many infrastructures are labeled "private cloud architectures" when they are really just a subset of a private cloud. The key points that tend to be missed, based on the NIST definition, are on-demand, self-service and measured service.
