Service and Data Security for Multi Cloud Environment

Rajkumar B, Balamurugan K

Software, storage data and infrastructure are shared under the cloud environment. Cloud computing provides many benefits in terms of low cost and accessibility of data. Cloud provider manages data values from the data owners. Risks of service availability failure and the possibility of malicious insiders problems are raised in the single cloud. A public cloud is offered by third-party service providers and involves resources outside the user’s premises. The cloud system is installed on the user’s premise under the private cloud model. Multi clouds or inter clouds are used to provide the reliable data delivery. Multi-cloud environment control several clouds and avoids dependency on any one individual cloud. Multi-cloud resource sharing scheme uses data and application partitioning mechanism. Four types of architectures are used to distributing resources to multiple cloud providers. They are Replication of applications, Partition of application System, Partition of application logic into fragments, Partition of application data into fragments. Replication of applications allows receiving multiple results from one operation performed in distinct clouds. Partition of application System into tiers allows separating the logic from the data. Partition of application logic into fragments allows distributing the application logic to distinct clouds. Partition of application data into fragments allows distributing fine-grained fragments of the data to distinct clouds. Data security and attack handling operation are managed by centralized or distributed manner in the cloud. Service and data management architectures are combined to provide a complete solution for security requirements. Multiparty communication based security system is used to improve the security over different clouds. Integrity is provided for data and service components sharing environment. An integrated intrusion detection system is proposed to handle malicious attacks.
