Development Methods

� Limit the Cost of Software Creation

�Research on

Improved Software Development Process

�Methods & Tools for Optimization of

Code & Run Time Systems

�Parallellization tools

Increasing worries about

� Cost of ownership…

� And hence increased research in

the domain of…

Deployment & Management

� Manage Total Cost of Ownership of Complex Software

Systems

� Techniques for Provisioning

� Service Management Platforms

� Policy Definition & Enforcement

� Mapping, Allocation, Load Balancing

Multi-agent Systems: autonomic computing

� Increase Autonomy of Individual Nodes, due to Decentralized Nature,

� Towards Autonomic Computing

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

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
