Brokering SLAs for end-to-end QoS in Cloud Computing

In this paper, we present a brokering logic for providing precise QoS levels to cloud applications distributed across a number of different business actors, such as network service providers and cloud providers. The broker is capable of composing a discrete number of available offerings from each provider, in a way that respects the end-to-end QoS constraints of applications, while minimising costs incurred by cloud consumers.
