Repository design strategies and discovery techniques for cloud computing

Cloud computing has emerged as one of the hottest area in the field of computer technology, which is used to deliver resources on demand. Users of the cloud can access the services published by the cloud providers. The availability of many cloud providers throughout the world has introduced the need for research in cloud service repository model and discovery. Searching a suitable cloud provider and a cloud service has become a tedious and time consuming task for the service user. There is a need to publish, store and discover suitable cloud providers and services for the users. The cloud service discovery mechanisms support the discovery of services based on functional and non-functional properties. This paper reviews various cloud service description architectures based on the location of availability of cloud service descriptions. It also classifies and gives taxonomy of cloud service discovery methods defined in the literature. The paper also classifies the discovery methods based on the cloud deployment models and describes the various service discovery algorithms used in the literature for cloud service discovery.
