Interaction among Cloud Services on Common Software Application with Service Level Agreement

Nowadays the cloud computing has plays important role for larger organization, IT Industries, educational industries etc. Cloud computing is the complex infrastructure of software, hardware, processing and storage that are available as a service. It has huge number of advantages and also suffers lot of disadvantages. In the Cloud Service User (CSU) point there is no specific protocol, algorithm. There is no design pattern and interface for accessing a cloud services. The Cloud Service Provider (CSP) has to follow their own deployment model which is difficult to understand by the cloud service users or application user. There is no interoperability among the cloud services with different cloud service providers. The proposed work focuses on the interoperability among the cloud service providers with common deployment model in order to provide the effective, reliable and efficient services. The cloud specific services are categorized into cloud sensitive services and cloud insensitive services. In the cloud insensitive services which are more common services can be shared among the CSP services without maintaining the same services into their own deployment model. The services are shared with the help of Service Level Agreement (SLA). Each and every service has to establish the SLA with other services for reusing the services
