Autonomic Resource Management with Support Vector Machines

The use of virtualization technology makes data centers more dynamic and easier to administrate. Today, cloud providers offer customers access to complex applications running on virtualized hardware. Nevertheless, big virtualized data centers become stochastic environments and the implification on the user side leads to many challenges for the provider. He has to find cost-efficient configurations and has to deal with dynamic environments to ensure service guarantees. In this paper, we introduce a software solution that reduces the degree of human intervention to manage cloud services. We present a multi-agent system located in the Software as a Service (SaaS) layer. Agents allocate resources, configure applications, check the feasibility of requests, and generate cost estimates. The agents learn behavior models of the services via Support Vector Machines (SVMs) and share their experiences via a global knowledge base. We evaluate our approach on real cloud systems with three different applications, a brokerage system, a high-performance computing software, and a web server.
