About GlassFish network topologies and load-balancing

Note: if you're reading this using a feedreader, please make sure you've updated to the updated TheAquarium feed.

Load-balancing is a topic that comes up often with GlassFish users and Markus has posted a piece covering both proxying and load-balancing.

He covers Unix techniques such as iptables, authbind and Apache mod_proxy as both a reverse-proxy or rewriting engine but also the Jsvc utility. He also touches on different load-balancing options: Oracle GlassFish Server, mod_jk, and mod_proxy_balancer. Feel free to share your load-balancing experiences on his blog.

Note that GlassFish 3.1.2 will strengthen its support for mod_proxy_ajp and that load-balancing provisioning is handled by early builds of GlassFish 4.0 as shown in this video from JavaOne 2011.

Webinar Replay : GlassFish 3.1 Clustering Deep Dive

The replay and Q&A transcript of yesterday's "GlassFish 3.1 Clustering Deep Dive" Webinar are now available.

John Clingan covers the clustering architecture changes with previous versions, the use of SSH, DAS (Domain Admin Server) scalability improvements, failover improvements with consistent hash algorithm for replicas and better performance, the new load-balancer configuration tool, and finally steps to deploy a highly-available application using the command line or the graphical admin. High availability of WS-ReliableMessaging and JMS services are also covered in this webinar.

Overall I found it to be a very well balanced and easy to follow webinar. Check it out! And remember to track all webinars (both upcoming and replays) at http://glassfish.org/webinars.

New Webinar Recording: Load Balancing GlassFish Clusters

ALT DESCR

Last month, John and Shreedhar gave a free webinar on High Availability through Load Balancing of GlassFish Clusters. The presentation was well attended, see posts from John and from an attendee, Daniel-Noz, and the recording of the webinar is now available.

As part of an effort to improve the effectiveness of this and other GF Portfolio Resources, I've created a very short Feedback Survey; please consider using it to help us help you.
