A Challenge for Security and Service Level Agreement in Cloud Computinge

One of the most promising field in computing is regarded as cloud computing, which allows users to store their data virtually over the cloud without the need of any fixed infrastructure. It offer user to manipulate their data regardless of the geographical position, hence providing a scalable, feasible and flexible way to connect user to their data. The cloud can be considered as of the Internet where data are usually stored and computing refers to the applications and services that it can provide. Users are connected to cloud by Cloud Service Providers through the Internet connection. Both users and cloud service provider agree on a protocol known as service level agreements for exchange of information. Cloud computing provides increase in capacity and grants the capability to perform computation on cloud infrastructure to its users. Cloud Computing is capable of providing more convenient communication and instant multi-point collaboration feature. Cloud computing provides better utilization of distributed resource over large amount of data and they can be access remotely through the internet. Quality of service should be kept in mind will designing the service level agreement. There are many problem related to cloud computing such as traffic managements, security and privacy. This paper provides a survey on the basic working principle of clouding computing. This paper provides an overview of the cloud architecture including the different types and level of clouds services. In this paper focus has been made upon the service level agreement, issue and security prospectus over the cloud computing.
