Interoperability Issues and Standard Architecture for Service Delivery in Federated Cloud: A Review

Cloud computing can be defined as accessing third party software and services on web and paying as per usage. It facilitates scalability and virtualized resources over internet as a service providing cost effective and scalable solution to customers. As the customer needs are growing for the solutions of the complex problem, there is the need for the services from different cloud service providers so that resources will be properly utilized. To execute and handle the complex business application over clouds as demands by the users, interoperable solution is provided. Federated cloud computation gives the advantage of cost reduction and energy saving. Cloud architecture uses virtualization technique for having the provision of more than one virtual machine on the same physical host. Interoperable cloud architecture solves the problem of vendor lock-in and portability, saves energy reduce power consumption and promote green cloud computing. This paper describes Interoperability issues and standard architecture of cloud computing suitable for the use of services from multiple service providers to provide portability.
