There are three core vendors and protocols supporting VDI today. Microsoft with RDP, Citrix with ICA, and VMware with PCoIP. For most organizations a single vendor approach has been necessary, primarily because the costs associated with the supporting network and application delivery network infrastructure required to deliver VDI with the appropriate levels of security while meeting performance expectations of users and the need to maintain high availability. It’s a tall order that’s getting taller with every mobile client introduced, especially when you toss in a liberal dose of enforcing policies regarding access to virtual desktops. Most folks are well aware of F5’s long history of deep integration with its partners Microsoft and VMware. Whether it’s integrating with management systems or designing, testing, and documenting the often times complex joint archite... (more)

Dear Slashdot: You Get What You Pay For

Open Source SSL Accelerator solution not as cost effective or well-performing as you think o3 Magazine has a write up on building an SSL accelerator out of Open Source components. It's a compelling piece, to be sure, that was picked up by Slashdot and discussed extensively. If o3 had stuck to its original goal - building an SSL accelerator on the cheap - it might have had better luck making its arguments.

Finding New Life For SOA in the Cloud

One such analyst is Daryl Plummer of Gartner. Daryl has always been very application focuse... (more)

Is Social Media a Hostile Work Environment?

The blurring of professional and personal lives in social media and the rush of organizations to “join in” may create just that. Almost every modern organization has behavioral policies known as “zero-tolerance” these days. These policies are designed to provide a healthy, productive environment in which anyone can work without fear of being insulted, offended, harassed, or otherwise made uncomfortable on a day to day basis. Basically, “zero-tolerance” policies are - in part - the codification of the common-sense rule that says you don’t talk about religion, politics, or sex in... (more)

Your Cloud is Not a Precious Snowflake (But it Could Be)

You can’t differentiate until you do something different Gartner analyst and cloud pundit Lydia Leong reminds us that without differentiation, all clouds look pretty much the same.  “These are traits that it doesn’t take a genius to think of. Most are known requirements established through a decade and a half of hosting industry experience. If you want to differentiate, you need to get beyond them.” [emphasis added] She lists traits common to most cloud providers: premium equipment, VMWare-based, private VLANs, private connectivity, and co-located dedicated gear but doesn’t real...
