ETTK self-healing and optimizing demo
Autonomic computing is one of the new hot buzzwords. However, not much has been done to provide an actual demonstration of what this technology is about in order to explain the hype. In this article, Alfredo Da Silva discusses an implementation that shows how practical autonomic computing can be. Complexity and high installation and maintenance costs are a reality of today's computer systems. This is mostly due to the fact that they are created to meet the specific needs of their owners and users. Once these systems are composed of several different components -- hardware, middleware (for example, Tomcat, WebSphere Application Server), applications -- and their management costs are higher them the costs of the components themselves.
These issues are addressed by the autonomic computing paradigm. It proposes systems that are environment and workload changes resilients, that heal themselves over failures and errors and proactively defend against attacks, bringing that way the overall management costs significantly down.
