I recently read a Bank of America Merrill Lynch report about cloud computing, and they described private clouds as "old wine in a new bottle." I think they nailed it! The report points out that a typical private cloud set-up looks much the same as the infrastructure components currently found in a corporate data center, with virtualization added to the mix. While the virtualization provides somewhat better server utilization, the elasticity and efficiency available in the public cloud has private clouds beat by a mile. In short, the term "private cloud" is usually just a buzzword for virtualized internal environments that have been around for years. By replicating existing data center architectures, they also recreate the same cost and maintenance issues that cloud computing aims to alleviate. Despite their limitations, there is still a lot of industry talk about c... (more)

Has Virtualization Solved the Data Center Crisis?

Over the past several years, many IT departments have committed to virtualization as an antidote to the spiraling costs and inflexibility plaguing corporate data centers everywhere. By running applications on virtual servers and consolidating underutilized hardware, data centers can get maximum value from their equipment. Virtualization also makes IT more responsive to the needs of the business: rather than spending weeks or months to provision a physical server, a virtual server can be launched in minutes. Virtualization was meant to be the solution to today's data center woes -... (more)

Amazon's VPC Opens the Door for Innovation and Enterprise Cloud Adoption

Cloud Computing Journal The recent announcement from Amazon of the Virtual Private Cloud (VPC) represents the next big advance in the evolution chain for cloud computing. Enterprises can now integrate their IT infrastructure with Amazon's vast computing and storage resources, using a VPN connection from their data center to their own virtual private cloud which then looks like part of their internal network. Until the release of VPC, companies were left to build applications and utilize the cloud as a separate and somewhat siloed portion of their computing environment. In addi... (more)

What IT Managers Should Learn from Public Clouds

Corporate computing is going through a fundamental shift — moving to a world that’s largely cloud-based, self-service, and highly virtual with shared resources. Rather than go through their IT departments like they have for decades, users will simply specify how many cloud servers they need and for how long, and provision their own resources with a few mouse clicks. I recently read an interesting post by Rodrigo Flores, observing that the growing acceptance of public clouds is also changing the role of corporate IT departments, and they’ll have to either adapt or die. I’d like to... (more)

Moving to the Cloud: How Hard is it Really?

Many IT managers would love to move some of their applications out of the enterprise data center and into the cloud. It's a chance to eliminate a whole litany of costs and headaches: in capital equipment, in power and cooling, in administration and maintenance. Instead, just pay as you go for the computing power you need, and let someone else worry about managing the underlying infrastructure. But moving from theory into practice is where things get complicated. It's true that a new web application built from scratch for the cloud as a standalone environment can be rolled out qu... (more)
