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 mission is to do just that. We tend to see the world from the data center out, unlike much of the innovation around cloud computing to date, which has focused on the cloud as a separate and silo'd environment. Enterprise Cloud Computing Hurdles We share the view held by many that the cloud will... (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. Once we’ve accurately defined the problems, we can address them with the right technology and processes. 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...

Cloud Computing: The New Normal in Enterprise Infrastructure

As we work with dozens of companies that are actively running pilots and doing early deployments in the cloud, it made me think about what the “new normal” will look like in enterprise IT infrastructure. A recent report from the Yankee Group shows that adoption of cloud is accelerating, with 24% of large enterprises already using IaaS, and another 37% expected to adopt IaaS within the next 24 months. It’s clearly a time of major shifts in the IT world, and while we wait for the hype to subside and the smoke to clear, some early outlines of the new paradigm are emerging. Here’s wh... (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)
