GlassFish High Availability Recap

Two recent high availability mediacasts, the GlassFish Clustering screencast and the recent GlassFish High Availability webinar (and companion whitepaper), have done well (IMHO).   To quickly summarize, the screencast covered download, setup, and validation of a GlassFish cluster. The webinar covered architectural approaches to deploying GlassFish clusters in a virtualized environment.

The screencast hit > 1,500 views in total (YouTube + Sun Learning Exchange). Time well spent on my part, I think. Hopefully it was time well spent on the viewers part as well.

As for the webinar, over 1,000 registered to attend the webinar, hundreds attended, and hundreds are viewing the replay. Lots of questions occurred during the chat, and some business relationships were formed in the process.

Me-thinks we've addressed a bit of pent-up demand on GlassFish High Availability.

GlassFish Clustering in Under 10 Minutes

As we add features to GlassFish over time, one characteristic we do not want to compromise is ease-of-use. With this screencast I wanted to show how easy it is to set up a GlassFish high availability cluster.  While other clustering screencasts exist, I wanted to take a different approach. How long would it take, from download to deploying an app, to get a GlassFish high availability cluster up and running? This screencast does just that. While I could have gone faster - faster connection, eliminate narration, etc - I wanted to make it more typical and meaningful for viewers. Here's a summary of the timing:

  • Download: 2 minutes and 30 seconds. I cover this time by describing bringing up a slide and describing the clustering architecture
  • Installation and cluster setup: 4 minutes, 30 seconds.
  • Verifying and testing cluster by deploying a sample application: 3 minutes

Note, the embedded video is via the Sun Learning Exchange. This video is also posted to YouTube.

Update: You can play these video's in full screen. On YouTube there is a "Watch in High Quality" link just under the video (to the right) as well.
