Chamaeleo: Toward Self-Managing Service-Oriented Applications

| Abstract | Service-oriented computing is slated to shape modern societies in vital areas such as healthcare, government, science, business, and finance. It utilizes services as the building blocks for developing collaborative applications, known as service-oriented applications (SOAs), distributed within and across organizations. The most common realization of SOAs is based on Web services, i.e., Web-accessible entities that provide pre-defined capabilities via message exchange. Current approaches for SOA management in dynamic environments are time-consuming and error-prone because of their burdensome human involvement. They provide limited abstractions to cope with the complex SOA development life cycle and required adaptation to changes. In this presentation, I will talk about Chamaeleo, our on-going project for enabling self-managing SOAs. These are SOAs that can manage themselves with minimal human intervention. Their autonomic features promise to eliminate much of the cost and difficulty required to manage dynamic SOAs. I will first present the major research thrusts addressed by Chamaeleo and overview potential application domains including e-science, e-learning, supply chains, and disaster management. I will then focus on change management and Chamaeleo's service replaceability and matching framework. In particular, I will describe a policy-based matching framework for dealing with failures and changes in dynamic service-oriented environments. |
