My View – Design documents, photos, image editing

Today was a documentation day. Yippee! Oh Visio, how you manage to manipulate the simplest lines into complex, tangled webs, one will never know.

What I do know is that PCoIP provided an excellent user experience when working with graphics in Visio. One of the great features of PCoIP is that it builds the image to full quality over time unlike some other protocols that will generate a fuzzy image when bandwidth is unavailable. Indeed, a nice feature when working with graphics and attempting to read the small print on drawings. Dragging objects, working with text, connecting devices, and editing images were all accomplished from within the virtual desktop with no frustrating waiting while the image is redrawn as in RDP. Keep in mind I am accessing a virtual desktop in Steelhead Data’s cloud in Sacramento, CA from my home office in Portland, OR.

Scott Davis, VMware View CTO, does a great job of describing the PCoIP technology in his blog

More importantly, by transmitting compressed bitmaps or frames, we can adjust the protocol in real time to account for the available bandwidth and latency of the communications channel. On a WAN connection with typically less bandwidth and higher latency, a less crisp image is produced quickly, typically with 0.2-0.5 bits/pixel producing a grainy, but still recognizable image. Kind of like an analog TV… This rapidly sharpens with increasing clarity and detail visibility with each succeeding frame until the image is perceptually lossless. This is a high quality image at a total of approximately 1-3 bits/pixel. Think of it as now Digital HD to stick with our TV analogy. On a higher performance LAN, the images become sharp instantly and will build to complete lossless at 5-15 bits per pixel. Think of it as Blu-Ray!

After completing some documentation, I shifted over to responding to customer requests in our managed services platform where we host VMware View desktops for businesses. Pros to using a View desktop: My desktop is located in the datacenter with the managed environment so connectivity to the infrastructure is fast and easy. Running tools such as the vSphere client to access the console of VMs from within the View desktop provides a better experience than if I run the same tool over a VPN connection on my local client. In the past I would have made a similar connection into a terminal server or Citrix environment where I could then access these tools. The difference here is that I have my own dedicated desktop where I get to install the tools that are useful to me like the great automation tool from thevesi.org for performing tasks in a vSphere environment. Or maybe I want to use the Webex one-click application. This is not something that I would want to install on a shared terminal server but it’s my desktop and I’ll do as I please! If an application decides to misbehave, I have the option of rolling back to a snapshot or refreshing my desktop to a point where it is running like a well oiled machine. Try doing that on a terminal server or traditional desktop.

This post is part of a project I am undertaking where I will be using a VMware View desktop for - hopefully - all of my work computing.  See more by clicking the "myview" tag.
