Cloud computing provides a mechanism to access, store and retrieve the applications and data online. The word cloud refers to a network or the internet. Nowadays, many IT Companies are adopting Cloud Computing. In Cloud, computing resources are made available to the users easily, quickly and on a pay-per usage basis. In this paper, an attempt has been made to analyze the cost involved in accessing the paid services of cloud and show how the service broker policy of retrieving data from the closest datacenter and retrieving data after optimized response time of the datacenters. After a close analysis, we find that retrieving data from the nearest datacenter is more cost effective than optimized response time data retrieval of data from datacenters.
