Cloud Expo 2010 Analysts, bloggers and mainstream media have spent 2009 promoting cloud computing as “the next big thing” that will revolutionize the way companies buy and use computing power. But beyond the hype and the C-level interest in an exciting trend, there’s value to the cloud that appeals to the pragmatic, “show me” nature of enterprise IT. The two main drivers for cloud computing are the same ones that have always motivated enterprise IT: save money (do more with less) and be more responsive to business needs. These goals are typically in conflict with each other, so that in tough times the first takes precedence and in boom times the second one does. The cloud offers the promise of being able to do both, which is why it so attractive to the CIO and IT managers. The cloud potentially lets you offload from your expensive internal infrastructure and scal... (more)

The Next Frontier in the Cloud: Legacy Apps

Although cloud computing momentum continues to build and scarcely a day goes by without a new cloud announcement or study, there’s been little real enterprise adoption and almost no meaningful case studies. In part, that’s because early cloud providers and vendors were focused on developers and technology start-ups when they designed their offerings, and larger, more established organizations were rarely on their radar screen. While start-ups can easily embrace new technologies and architectures, enterprises have far more constraints and have been largely limited to “tire kicking... (more)

Moving to the Cloud: Managing Your Environment

Cloudonomics Journal This post is part of a series examining the issues involved when moving applications between internal data centers and public clouds. One of the advantages of cloud computing is that someone else is managing the infrastructure – including the servers, network devices and storage systems, not to mention the data center power conditioning, cooling and fire suppression equipment.  One of the costs of offloading this infrastructure is that the cloud becomes something different and separate from your data center.  In most deployments today, the cloud is almost com...

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 ...

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)
