Security & scalability architecture for next generation internet services

Next Generation Internet Applications will experience many paradigm shifts from what we have seen so far. Through various technologies like applications mash-up, content aggregations, grid computing, cloud computing, Web 2.0, Web 3.0, applications will have to adopt novel software engineering techniques for development and deployment. Scalability, Interoperability, Availability (tolerance to failure), Accounting (journaling, billing), and Security (confidentiality, integrity, authentication, authorization), and Anonymity are some of the important quality and usability features that will determine the success of new Internet applications. This position paper proposes how these complex challenges can be managed.
