Around June of 2006 I created a video for Citrix that explains how the UPDv3 printing engine works in Presentation Server 4.0. That video is available on the Presentation Server landing page under Technology Videos. Brian Madden has also done several videos on farm design, Speedscreen technologies, etc. I personally think that some of these videos are a great way at getting a better understanding of how these technologies work in a quick 30 minute view versus spending tons of time reading documentation and white papers. I highly recommend that you check them out.
Here’s a link to the Citrix Technology Videos for Presentation Server
Also, I’d love to hear feedback on what other topics that you’d like to see in a Citrix Technology Video? Would you like to see more information on Streaming Server/Tarpon, Web Interface/Secure Gateway, Health Monitoring in PS4.5? Please post your thoughts below.
