Abstract
In Cloud computing PPH private public and hybrid respectively the cloud environments are available in now a days. Cloud computing has many benefits and security challenges in various cloud environments. But regarding some business-critical applications, the organizations, especially large enterprises, still may not move them to cloud. The market size of the cloud computing shared is still far behind the one's expectation. From the consumer's perspective, cloud computing security concerns, especially protecting critical information in various cloud environment issues, remain the primary inhibitor for adoption of cloud computing services. This paper provides the benefits and security challenges in various cloud environment and techniques and solution for various issues of security challenges of various cloud environments. Finally, this paper describes future research work about protecting critical information in cloud by using all these techniques to overcome time process by using utilities in cloud computing by the reduce cost by performing better way.
