Abstract
In this paper, we propose and implement a distributed autonomic manager to maintain service level agreements (SLA) for each application' scenario. The proposed autonomic manager seeks to support SLAs by configuring bandwidth ratios for each application scenario using overlay network before provisioning more computing resources. The most important aspect of the proposed autonomic manager is scalability which allows us to deal with geographically distributed cloud-based applications and large volume of computation. This can be useful in look ahead optimization and when using complex models, such as machine learning. Through experiments on Amazon AWS cloud, we demonstrate the elasticity of the autonomic manager.
