Security Challenges and Solutions for Federated Clouds

Abstract

Cloud computing play a major role in information technology industry. In IT industry data are outsourced to the cloud. In these way part of information as Data as a service. Cloud computing as outsourcing the resources over the internet. They provide a services such as Infrastructure as a service, software as a service, and Platform as a service and some cloud models such as Deployment model, it contains four ways private, public, community and hybrid cloud models. The third party needed for outsourcing the data. Cloud federation brings together different service providers and their offered services so that many Cloud variants can be tailored to match different sets of customer requirements. To mitigate security risks and convince hesitant customers, security must be an integrated part of the federated Cloud concept. This paper surveys the state of the art in Cloud computing security, identifies unsolved issues related to federated Clouds, discusses possible approaches to deal with the threats and points out directions for further work.
