Cloud computing is an environment that plays an vital role in business or in an IT sector for the data storage. Now- a-days petabytes of data is being stored for their future use in order to retrieve the data. This paper proposes a Secure Cloud Computing Adoption framework for automatic intrusion detection, Identity management of users and service provider and key seed mechanism. Multicloud Service provider is held to provide authentication for the users, in order to provide prevention of the attackers or an hackers. we describe a framework for data and operation security in IaaS, consisting of protocols for a trusted launch of virtual machines and domain- based storage protection. Thus once the user is authenticated they will be launched in virtual machines where they initiate the upload process into the cloud. Keywords- virtual machines, domain-based storage protection,, Multicloud service provider, Attribute Based Encryption, Automatic Intrusion Detection, Key seed mechanism.
