DISCLAIMER: This is long and the opinions are mine. I’ve written a good bit here about the various ways Microsoft and Citrix overlap in the hypervisor space, ranging from topics like shared code base through competition for the desktop space. To me, these two players have always been the underdogs battling for the right to go head-to-head against VMware in the main enterprise (and now cloud) virtual data center event. I’ve long said here that I think Microsoft is in the best position to make that move, but to be honest, Citrix currently has better technology. In other words, Microsoft has a better strategic play, Citrix a better tactical play. The announcements that came of out Synergy last week prove that. Citrix knows what it’s doing and they know how to build virtualization products to compete with VMware. As has been asked many times before, here and elsewhere:... (more)

Security Cloud Assumptions

After pushing my latest post, Securing the Cloud: Shared Hardware and the Data Plane, Hoff posted a series of excellent questions and responses to the post via Twitter. I thought responding via another blog post, so that his questions could be addressed alongside my last post, was the way to go. I’ve trimmed some of his questions here for brevity but all of his questions can be found on his Twitter stream. And here we go. @thevirtualdc I hate to tell you this, but your last blog isn’t about securing “the Cloud” at all. You are interchanging cloud & virt… You are correct that I am... (more)

Choosing Between Azure and VMM Private Clouds

I’ve spent the past day reviewing all that’s floating around the Interwebs on the Azure announcements from the WPC this week. There are definitely a lot of nice nuggets to digest and stuff that’s going to take a while to process. Most of the Azure talk at WPC has been, as expected, about how partners can benefit from and build solutions on top of Azure. That’s a compelling message and one I think Microsoft got 100% correct. Now if only they’d franchise Azure we’d really be cookin’ ;). But what about enterprise customers using Azure? Since enterprise virtualization is the overwh... (more)

Security Implications of Virtualization Platforms in the Virtual Data Center

According to Forrester Research, 42% of all enterprise server resources will be virtualized by 2009. [1] Referred to by many names - server virtualization, OS virtualization, kernel virtualization - virtual machine (VM) platforms, such as VMware ESX and Microsoft Hyper-V, are typically the first forms of virtualization introduced to the data center. These technologies are becoming both less expensive and more accessible, making them attractive candidates to be the first virtual "guinea pigs" in the data center. Factors such as consolidation, cost savings, dynamic provisioning, ... (more)

Regional Cloud Computing Providers

One of the oft discussed business challenges of cloud-based application deployments – or any remote app deployment where a service has to communicate over the public internet – is latency. It takes more time to fetch data when a request has to leave the LAN, and latency is usually variable and at the mercy of both the Interwebs and the cloud provider. This isn’t so much of an issue when your entire app is deployed in the cloud and users are going directly there for data; the user won’t notice any difference between accessing your app after it’s moved to AWS than they did when y...
