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, VPC allows cloud users to control their IP addressing within the Amazon cloud (previously IT addresses were assigned randomly). This may sound trivial, but it solves some tricky problems that made it hard to integrate cloud and internal resources. Prior to VPC, every time you started a serv... (more)

What Does Enterprise IT Really Want from Cloud Computing?

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, s... (more)

Networking in Federated Clouds - The L2/L3 Debate

Last week Citrix announced OpenAccess and OpenBridge, two new offerings for cloud computing.  OpenAccess focuses on single sign-on and identity management while OpenBridge is designed to allow connections between local resources and cloud resources.  The OpenBridge announcement highlights an interesting debate occurring around hybrid cloud computing – how should cloud networks be connected? The debate centers on layer-2 versus layer-3 connectivity.  Traditionally, network topologies for remote data centers, co-location facilities, and managed services have been built with layer-...

A Cloud Security Bill of Rights

Cloud security remains a top concern for enterprise cloud deployments. Unresolved policy and control issues make it difficult to meet the requirements of corporate security and networking teams. As a result, we frequently hear from our customers that they assume they can only put the lowest-risk data and applications into the cloud – or that their cloud projects are on hold till the security issues get resolved. This is a major limitation for cloud adoption, often creating a false belief that the cloud only works for apps “that don’t matter,” or for companies who are willing to... (more)
