GlassFish on CMT Systems

An excellent paper on improving performance of GlassFish using Enterprise Manager on CMT systems has been published. The paper outlines various CMT systems and benefits of using CMT systems for Web 2.0 technologies. It follows up by taking a out-of-box GlassFish and using the Enterprise Manager to tune the performance. In a few clicks, where you enter information on the number of cores that GlassFish is running on, the Enterprise Manager tunes the system to deliver 8x (yes!) improvements.

The paper is titled  Optimizing Sun GlassFish Enterprise for Sun Open Network Systems. To learn more about GlassFish and GlassFish Portfolio: sun.com/glassfish.

Check out the paper - very useful information!

Carrier Grade Converged Services with SailFin and MySQL Cluster

Convergence of communications network onto IP based networks, provides an opportunity to Communications Service Providers (CSPs) to reach new markets. To implement solutions for these markets, require the solutions to be highly available, have high throughput and scalability and minimal latency.

The recently published Carrier Grade Service Execution Environment paper outlines an Event Driven Architecture solution using open source components. Sun GlassFish Communications Server (SailFin) and MySQL offer means to achieve high scalability, throughput for Communications Service Providers. 

Although the paper outlines solutions for Communications Service Providers, it is an interesting read from an application server (hint GlassFish). A typical Application Server administrator can glean interesting information on scaling their appserver as well.
