Almost every definition of cloud, amongst the myriad definitions that exist, include the notion of multi-tenancy, a.k.a. the ability to isolate customer-specific traffic, data, and configuration of resources using the same software and interfaces. In the case of SaaS (Software as a Service) multi-tenancy is almost always achieved via a database and configuration, with isolation provided at the application layer. This form of multi-tenancy is the easiest to implement and is a well-understood model of isolation. In the case of IaaS (Infrastructure as a Service) this level of isolation is primarily achieved through server virtualization and configuration, but generally does not yet extend throughout the datacenter to resources other than compute or storage. This means the network components do not easily support the notion of multi-tenancy. This is because the infrastru... (more)

Doing VDI, Only Better

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 o... (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. But it wanted to compare an Open Source solution to a commercial solution. That makes sense, the author was trying to show value in Open Source and that you don't need to shel... (more)

Finding New Life For SOA in the Cloud

We’ve been having quite a few discussions with analysts over the past few months on the subject of “cloud”. The interesting thing about these discussions is the vast array of points of view from which those analysts are viewing “cloud”. Some are focused on the network aspects, others on pricing/differentiation, and some are even very focused on what “cloud” means to applications – and the organizations that will, allegedly, take advantage of the cloud as a means of application deployment. 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)
