Virtualization continues to receive attention in enterprise organizations wanting to reduce IT costs and create a more flexible, efficient and automated applications workload environment. But once you've virtualized your server room, what's next? Some organizations are looking at a private cloud (also called an internal cloud or corporate cloud), an enterprise computing architecture that's protected by a firewall.
The goal of the private cloud model is to allow an administrator to manage his technology infrastructure from a single point and assign resources as needed. Owning and managing a private infrastructure may be less cost-effective for a business, but it increases the organization's ability to manage and protect data. This is especially important for businesses that have strict compliance regulations. This guide looks at the trends, best practices and criteria for building a true strategy around virtualization and the private cloud.

Virtualization has profoundly changed the IT industry, and the technology will continue to have an impact as it matures and evolves. This e-book, Introduction to Virtualization, covers the basics of the technology for IT professionals who want to reap the benefits of virtualization in their data centers. In addition to the basics of virtualization technology, the e-book covers disaster recovery (DR), server consolidation, testing and development, high availability, storage, security, and the three key virtualization platforms: Microsoft Hyper-V, Citrix XenServer and VMware ESX.

With so many options -- application virtualization, application or OS streaming, virtual desktop infrastructure and desktop virtualization -- companies are also still getting a handle on the terminology. Get the FAQs on virtualization.
A private, or internal, cloud is a means of centralizing data center resources and delivering them on the fly as business demands change and IT attempts to become a service delivery unit to the company. With server virtualization as its basis, cloud technology has a way to go, but CIOs are finding it a powerful vision.

challenges and benefits of a private cloud
A private cloud may leverage server virtualization to drive business flexibility, but many of its management challenges (both people and boxes) are as yet untested.
Lynch travels rocky road to 'stateless computing'
Merrill Lynch touted its "stateless computing" cloud at LinuxWorld. But one analyst countered that the project pushed the limits of technology to the edge.
There are no shortcuts or magic formulas to proper deployment and management of a private cloud. Any private cloud project must begin with a strong foundation and a realistic appraisal of the current environment -- particularly server virtualization -- and weigh that against the company's future needs for intracloud services and quality of service.

William Brogden discusses how you can move all or part of your server load to the cloud, pay for only the services used, and not waste efforts on extra hardware.
As hosting and service providers seek out the most efficient and powerful infrastructures for their "cloud" support capabilities, high utilization and lowest total costs become imperative. Amazon.com, Google Inc., Yahoo Inc., IBM, Hewlett-Packard, EMC Corp., Sun Microsystems Inc. and Microsoft are all building huge cloud compute capabilities. Large enterprises and governments that also seek high performance and lowest costs will and should seek to emulate these providers and create "private cloud" data centers where it makes sense.

Development coming to a cloud near you
Cloud computing platforms allow developers to write applications with scalability built into the underlying infrastructure. But not all is the same in the cloud.
All the risks to sensitive corporate data associated with outsourcing apply to cloud computing, and then some. Enforcing security policy and meeting compliance requirements are tough enough when you deal with third parties and their known or unknown subcontractors, especially on a global scale. Add the blurry characteristics of the cloud and the entry of nontraditional vendors into the technology market, and some red flags go up.
