Cloud computing is that the apply of employing a network of remote servers hosted on web to store, manage and method information on demand and pay as per use. It provides access to a pool of shared resources rather than native servers or personal computers. As it doesn’t acquire the items physically, it saves managing value and time for organizations. Cloud computing could be a utterly web dependent technology wherever consumer knowledge is hold on and maintain within the knowledge center of a cloud supplier like Google, Amazon, Microsoft etc .Cloud computing is an rising domain and is acclaimed throughout the globe. There are some security problems locomotion in whereas mistreatment services over the cloud. This analysis paper presents a review on the cloud computing ideas moreover as security problems inherent inside the context of cloud computing and cloud infrastructure. This paper additionally analyzes the key analysis and challenges that presents in cloud computing and offers best practices to service suppliers moreover as enterprises hoping to leverage cloud service to enhance their bottom line during this severe economic climate and intensify its usage. The main stress of our study supported existing literature and to know the idea of multi-tenancy security issue.
