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)

Holiday Presents from the Cloud

Cloud Expo New York As the year winds down, there are a few things I have come to expect: holiday parties, snow, and new features from cloud providers.  This year exceeded all of my expectations, starting with a note in early December from our friends at Terremark letting us know that they have fixed their Windows pricing for cloud servers.  Until this upgrade, if you started a Windows server in their cloud, you had to pay for a whole month of Windows licensing ($30-$100 depending on the version) no matter how much you used the server. This was rather un-cloudlike, where we want ...

True Isolation Makes the Public Cloud Work Like a Private Cloud

Security is always mentioned as a key factor limiting cloud adoption, but what does “security” really mean in the cloud? To understand the potential risks of cloud computing—and how to address them—we need to be more specific.

When you get into specifics with CSOs and risk managers, security concerns in the cloud can essentially be boiled down to two main issues: It’s a shared environment: In a multi-tenant public cloud, you’re sharing resources—servers, cloud networks, and sto...

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

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 addition to the VPN connection... (more)
