Climate change and the impact it has on our lives have forced many governmental and also
non-governmental organizations to conceive of new rules, regulations, and standards to
control CO2 and greenhouse gas (GHG) emissions. Calculating the energy efficiency and
reducing the electricity consumption in data centers are important steps towards greening
the IT in organizations. Several studies have shown that by migrating into the cloud,
companies in most cases could reduce their costs in addition to decreasing their greenhouse
gas emissions.
Unfortunately, lack of guidelines and varying and limited services from different cloud
providers, have made the adoption of appropriate Cloud services a challenge for many
organizations. In this regard, there is a vital need to study and analyze available services
from different cloud vendors and provide enterprises with the best solutions available
regarding their specific business requirements.
This thesis focuses on cloud computing and its efficiency for individual organizations. It
attempts to study the potential benefits of cloud computing by taking the environmental
and energy consumption advantages into consideration.
Cloud Computing is not a new concept and has been a hype term in recent years. Cloud
computing is based on the available technologies and it is all about using a new term for
the existing technologies. But the question is why to create a new name for what already
exists? The answer to this question is closely related to the potential that Cloud computing
has for organizations. It is all about conversion of capital expenditure (CAPEX) to the
operational expenditure (OPEX) and the possible advantages that this conversion could
have for any organization that choses to migrate into the Cloud.
In the following, upon introducing the cloud computing concept and its related technologies,
business functions and processes, information systems available for enterprises are explored.
Later, based on the required business processes and functions of organizations, a
comprehensive market analysis is carried out. For this purpose different cloud providers and
their available services are analyzed.
I developed an ontology for cloud computing based on the market analysis.
This thesis is an attempt to make the process of mapping business processes/functions to
cloud services easier by providing organizations with a matrix of cloud services/business
processes (distribution of market) and an ontology for cloud computing.
