Cloud services, delivered over the Internet, are designed in a way so that they can provide anytime and anywhere access to various applications and resources hosted in a cloud. The number of cloud providers is significantly increased as cloud has become an attractive marketplace for online service provisioning. Cloud providers offer various services (email services, data storage services, document sharing services, video conferencing services) to consumers but with varying levels of QoS. Thus, selecting better cloud services has become challenging task for cloud consumers. The process of selecting cloud services involves various factors such as characteristics and models of cloud services, user requirements and knowledge of cloud technologies. This talk will explore cloud service selection tools, techniques and models by taking into account the distinguishing characteristics of cloud services. It will discuss the development of a new framework for cloud service selection that takes into account QoS attributes of services. The talk will also identify directions for future research in cloud computing.
