HA-OSCAR: the Birth of Highly Available OSCAR
Telecom applications must be built to face extreme or unplanned conditions of execution. Even in typical real-life situations, subscribers are putting a lot of pressure on carriers because of their high expectations regarding system performance and availability. Customers do not expect these applications to fail or their phone requests to be delayed beyond a typical threshold. This is increasingly true as telecom applications are providing additional services, some requiring real-time characteristics.
Carrier-grade applications must be designed with these subscribers' constraints in mind, taking into account the cost of software maintenance and upgrades, service availability and scalability. Complex distributed software demands a specific programming paradigm. It has been proven over the years that complex system interfaces tend to increase the time to debug and the probability of application failure.
AEM (asynchronous event mechanism) provides an event-driven methodology of development in order to provide robust applications with a mechanism that allows reacting quickly to system events by means of user-space callbacks. In the AEM implementation, the kernel plays a major role in handling events and increases the reliability of applications. For this reason, AEM provides a flexible solution for application designers, supplying an extensible framework that allows new functionalities to be added at runtime, without rebooting the system or restarting applications. In order to reach carrier-grade requirements, HA-OSCAR plans to supply efficient support for asynchronous events.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
