The
ever-increasing density in cloud computing parties, i.e. users, services,
providers and data centres, has led to a significant exponential growth in:
data produced and transferred among the cloud computing parties; network
traffic; and the energy consumed by the cloud computing massive
infrastructure, which is required to respond quickly and effectively to users
requests. Transferring big data volume among the aforementioned parties
requires a high bandwidth connection, which consumes larger amounts of energy
than just processing and storing big data on cloud data centres, and hence
producing high carbon dioxide emissions. This power consumption is highly
significant when transferring big data into a data centre located relatively
far from the users geographical location. Thus, it became high-necessity to
locate the lowest energy consumption route between the user and the
designated data centre, while making sure the users requirements, e.g.
response time, are met.
The main
contribution of this paper is GreeDi, a network-based routing algorithm to
find the most energy efficient path to the cloud data centre for processing
and storing big data. The algorithm is, first, formalised by the situation
calculus. The linear, goal and dynamic programming approaches are used to
model the algorithm. The algorithm is then evaluated against the baseline
shortest path algorithm with minimum number of nodes traversed, using a real
Italian ISP physical network topology.

The use of cloud computing can increase
service efficiency and service level agreements for cloud users, by linking
them to an appropriate cloud service provider, using the cloud services
brokerage paradigm. Cloud service brokerage represents a promising new layer
which is to be added to the cloud computing network, which manages the use,
performance and delivery of cloud services, and negotiates relationships
between cloud service providers and cloud service consumers. The work
presented in this paper studies the research related to cloud service
brokerage systems along with the weaknesses and vulnerabilities associated
with each of these systems, with a particular focus on the multicloud-based
services environment. In addition, the paper will conclude with a proposed
multi-cloud framework that overcomes the weaknesses of other listed cloud
brokers. The new framework aims to find the appropriate data centre in terms
of energy efficiency, QoS and SLA. Moreover, it presents a security model
aims to protect the proposed multicloud framework and highlights the key
features that must be available in multi-cloud-based brokerage systems.
