ENHANCEMENT ON ADAPTIVE RESOURCE PROVISIONING FOR READ INTENSIVE MULTI-TIER APPLICATION IN THE CLOUD

ABSTRACT With the growth of information technology, most important service is computing that meets every day needs of general community. Cloud computing is that type of computing model which uses computing resources for delivering information technology services over a network. A Service-Level Agreement (SLA) guarantees for specific quality attributes to the consumers of services such as response time, throughput etc. This paper proposed a system which addresses software configuration management. For example, we assume that the number of connections from each server in the Web server tier to the database tier is sufficient for the given workload. The proposed system also resolve problem for automatic detection and resolution of bottlenecks in a multi-tier Web application hosted on a cloud in order to provide surety of maximum response time requirements, in order to guarantees service level agreement i.e. response time. It also defines a method for identifying and retracting over provisioned resources in multi-tier cloud-hosted Web applications.
