Cloud Service Brokers: Addressing the New Cloud Phenomenon

Abstract

The concept of cloud computing with on-demand provisioning of a shared pool of configurable computing resources of unprecedented size, elastic scalability, and ubiquitous network service accessibility has gained huge momentum in the IT industry and is high on the agenda of the industry and research community from developer as well as from end-user perspective. However, there are many issues faced in migrating existing systems into the cloud and between providers that have led to its slow adoption. Cloud service brokers (CSBs) have emerged as a solution to address this growing need and provide services that facilitate smooth cloud adoption, management, migration, and maintenance for cloud users and providers. This chapter addresses this new cloud phenomenon by reflecting on cloud adoption and migration challenges and presenting an overview of CSB utilities and the proposed concept of CSB registry.
