A Novel Approach for Elastic Query Processing in the Cloud

Cloud computing is a promising model of serviceoriented computing. One major advantage of cloud computing is its elasticity, i.e., the system's capability to supply and take away resources dynamically at runtime. For that, it's essential to design and implement a systematic and effective technique that takes complete advantage of the system's potential flexibility. This paper presents a non-invasive approach that monitors the performance of relational database management systems in cloud infrastructure, and dynamically makes choices to maximise the effectiveness of the provider's environment whereas still satisfying specified service level agreements" (SLAs).
