Wow! 2012 has been a great year for the open cloud at Rackspace.
QoS is a set of technologies for managing network traffic in a cost effective manner, to enhance user experiences in enterprise environments, as also in home and small offices.
With the success of virtualized datacenters, IT organizations and hosting providers (providers who offer colocation or physical server rentals) have begun offering more flexible virtualized infrastructures that make it easier to offer on-demand server instances to their customers.
The Hyper-V Virtual Switch is a software-based layer-2 network switch that is available in Hyper-V Manager when you install the Hyper-V server role.
A load balancer provides the illusion of a single IP address (Virtual IP address or VIP) to clients requesting a service. The service is implemented on multiple different IP addresses (Direct IP address or DIP).
The following diagram shows an example deployment of two customers moving in a cloud datacenter with the CA-PA relationship defined by the Hyper-V Network Virtualization policies. Consider the example in Figure 5. Prior to moving to the hosting provider's shared IaaS service:
Cloud Computing is a term that is often bandied about the web these days and often attributed to different things that -- on the surface -- don't seem to have that much in common. So just what is Cloud Computing?
My esteemed co-tormentor of Twitter, Christian Reilly (@reillyusa,) did a fantastic job of describing the impact — or more specifically the potential lack thereof — of Facebook’s OpenCompute initiative on the typical enterprise as compared to the real target audience, the service provider and manufacturers of equipment for service providers: …I genuinely believe that for traditional service providers who are making investments in new areas and offerings, XaaS providers, OEM hardware vendors and those with plans to become giants in the next generation(s) of Systems Integrators that the OpenCompute project is a huge step forward and will be a fantastic success story over the next few years as the community and its innovations grow and tangible benefits emerge.
You or may not believe this, but I think we've reached a point with Cloud Computing where the discussions centered around "definitions" are almost over and we'll quickly be moving into a stage of people/companies wanting to do stuff.
The need for cloud provider price transparency. What is a workload and how to move it. “Open”ness and what it means for a cloud service.

Mike Dahn pinged me via Twitter with an interesting and challenging question: I took this as a challenge in 5 minutes or less to articulate this in succinct, bulleted form.
I was speaking to an enterprise account manager the other day regarding strategic engagements in Cloud Computing in very large enterprises. He remarked on the non-surprising parallelism occurring as these companies build and execute on cloud strategies that involve both public and private cloud initiatives. Many of them are still trying to leverage the value of virtualization and are thus often conservative about their path forward.
The pace of innovation in the cloud in the last few years has been astounding. It's difficult to recognize today's cloud computing landscape as having any relationship to where it was a year ago.
