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 allocation size limits to the ways in which storage is managed. These are just some of the things you’ll want to consider as you start to think about integrating cloud computing into your existing IT environments. I’d like to focus in detail on the complexity and variability of cloud provisi... (more)

Making Cloud Computing Secure for the Enterprise

Cloud Expo on Ulitzer For cloud computing to gain traction in the enterprise, IT and security executives need to be certain that their company’s applications and data are safe. But when security is partly out of enterprise control, it becomes impossible to know if sensitive information has been accessed or compromised. Today, using a public cloud means moving from an internal environment where a company has complete control of data and processes to an environment where that control belongs to someone else, and is often opaque. Within the cloud, applications run in a multi-tenant ... (more)

Hubs, Spokes and WANs

Recently, we’ve had a number of discussions with enterprises about how they’d like to use the cloud. The basic use case is around capacity on-demand (not surprisingly), but the specifics have raised some interesting issues. The companies have distributed branch offices that need the capacity for a range of applications, including dev/test environments as well as back-office and web apps. Today, these distributed groups are relying on corporate IT to meet their scaling and infrastructure needs, and they are frequently bottlenecked. This is both in terms of overall challenges in ...

Private Clouds: Old Wine in a New Bottle

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... (more)

New CloudSwitch Blog for Enterprise Cloud Computing

Welcome to our enterprise cloud computing blog where we'll share our perspectives on cloud computing trends and best practices for the enterprise. We're a team with extensive experience in IT software and systems (learn more about us), and we're passionate about the opportunity that cloud computing offers for fundamentally improving enterprise IT. However, we believe that before the cloud can reach its potential, some innovation needs to take place within the enterprise data center to make cloud computing simple, secure and tightly integrated with existing IT infrastructure. Our ... (more)
