Architecting Scalable Cloud Infrastructure to Support High-Volume OSS/BSS Workloads in Real-Time Environments

Cloud computing provides a new impressive model of IT architecture which offers new methods for development, maintenance and management of scalable applications. With the growing interest and acceptance of the Internet economy, as well as the continuous improvements of data storage and computing capacities, more and more IT resources have been set up out of the local Intranet infrastructures. Applications are being developed and re-architected to be deployed and externally hosted in a privately managed or publicly outsourced distribution of data flows, databases and processing nodes around the Internet. Such applications must ensure reliability and availability at affordable costs, efficiency of resource usage and must have small or zero maintenance overhead. This poses new challenges in the design and implementation of such large-scale distributed applications relying on clusters of distributed machines whose performances heavily depend upon the design of the Bus and of the interconnection links.
