Designing scalable, reliable, and efficient systems

Designing Scalable, reliable and efficient systems is the goal of systems engineering. We see that in the way Google scales their services to billions or the Amazon cloud. But before the internet big boys, this used to be the sole domain of the telecom guys. Well, it still is their domain because there are nearly 4 billion cell phones and god knows how many landline phones in operation. Switches that set up all these calls are quite hard to build.

Today, Andreas Burmester sent a link to a paper that appeared in Ericsson Review. It describes how they built a full system for delivering continuous services using only open source components. Notable how they depend on Java EE and GlassFish Communications Server in the middleware tier. They used Open SAF and Linux clustering at the lower levels.
