Architectures to Survive Technological and Business Turbulences

Survivable architectures are needed so that the current and future systems can tolerate the usual turbulences of technology and business climate. This paper, based on insights gained through practical experience with several architectural projects in the telecom industry and active participation in the standards bodies, highlights the work being done on survivable architectures. Instead of presenting theoretical models, this paper relies on best practices and explains the concepts through a detailed case study. In particular, the concepts of separating the technology independent models from the technology specific models and externalizing the business process flows from the system components are shown to be of practical value.
