Resource Allocation in Cooperative Cloud Environments

In cloud computing environment, cloud application services and resources belong to different virtual organizations with different objectives. Each component of cloud environment is self-governing and self-interested. They share their resources and services to achieve their objectives. The cloud computing environment provides infinite number of computing resources such as CPU, memory and storage to the users in such a way that they can dynamically increase or decrease their resources and its use according to their demands. In resource allocation model having two basic objectives as cloud provider wants to maximize their revenue by achieving high resource utilization while cloud users want to minimize their expenses while meeting their requirements. However, it is essential to allocate resources in an optimized way between two parties. In some situations, single cloud may not satisfy all the requirements of the users. To achieve this objective, two or more cloud providers cooperatively work together to satisfy the user’s requirements. These cooperative cloud providers should share and optimize the computational resources in a reasonable technique to make sure that no users get much resource than any other users and also improve the resource utilization.
