Clustering in GlassFish 3.1 - a fundamental article
By alexismp on Mar 13, 2011
With clustering being such an important new feature in GlassFish 3.1, it's important to get the vocabulary right and to understand the key concepts and features in the product. This is exactly what this detailed article written by the key engineers behind the implementation is set to do.
Tom, Bobby, Joe and Mahesh discuss basic clustering concepts, define what DAS, nodes, GMS, and HA are in the context of GlassFish and offer a description of the admin server and of the overall cluster architectures. The article also discusses the key role played by ssh and what it takes to install and administer such an architecture.
This is probably a good time and place to remind you that GlassFish 3.1 comes with full documentation: 20+ guides from quick-start to tuning.
