- Distributed software systems are increasingly important as organizations collaborate over networks. This requires appropriate distributed software architectures, development methods, and management techniques. - Key architectures discussed include service-oriented, peer-to-peer, sensor networks, and cloud/grid computing. Middleware is important for supporting distributed applications across different platforms. - Managing the total cost of ownership of complex distributed software systems is a growing concern, requiring techniques for provisioning, policy definition, load balancing, and more. Autonomic and self-managing techniques aim to increase system autonomy. - Several example distributed software platforms and applications are presented, including for telecom, healthcare, personal content sharing, and sensor networks. Security and policy-driven approaches

- 12. Challenges Policy-driven middleware for the advanced configuration of services requires: An expressive policy language that can be used in different areas and domains The enforcement of the policies at the underlying middleware layers The capability to reason about large sets of policies
- 13. Achievements Our policy-driven middleware Uses policies for the advanced configuration of services in different areas and domains Not only by programmers but also by non-experts and end users Simplifies adoption by integrating policy enforcement into the middleware infrastructure Supports validation and consistency checking over large policy sets Typically generated by multiple actors and stakeholders
