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?

Cloud Computing Journal 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 t... (more)

Moving to the Cloud: Key Considerations for Cloud Storage

This post is part of a series examining the issues involved when moving applications between internal data centers and public clouds. The true challenges in storage and data management in the cloud result from the diverse and often unfamiliar processes and infrastructures offered by the cloud providers, including: new provisioning methods, storage properties, data population and transfer, and systems for data management (snapshots, clones, replication, backup). The cloud providers define the relationship between servers and storage and often impose constraints on everything from ... (more)

Cloud Federation and the Intercloud

5th International Cloud Expo New York Last week's post explored federation in the cloud, allowing enterprises to move workloads seamlessly across internal and external clouds according to business and application requirements. Advances in federation are good news for companies considering a move to the cloud since deployments no longer need to be custom projects and applications no longer have to be tightly coupled to a particular cloud. To follow up, there's been lots of discussion recently about the concept of the "Intercloud," a direction for cloud computing that is closely rel... (more)

After Security, Network Bandwidth is the Next Cloud Bottleneck

Security concerns (real and imagined) have long dominated much of the cloud conversation and caused many companies to deliberate about getting started in the cloud. Slowly, the security issues are being addressed--through the adoption of corporate policies for cloud usage, maturing cloud provider offerings, and by technologies such as CloudSwitch which isolate and encrypt all cloud resources to meet the requirements of the CSO. But while the focus has been on cloud security, another potential bottleneck is on the horizon as companies start using the cloud in more substantial ways... (more)
