Introduction
“There was a time when every household, town, farm or village had its own water well. Today, shared public utilities give us access to clean water by simply turning on the tap; cloud computing works in a similar fashion.” That was the analogy used by Vivek Kundra, Federal Chief Information Officer (CIO) of the United States Government to depict the use of cloud computing in today’s society. As the corporate world has embarked on the interactive platform of Web 2.0, some companies are progressing one step ahead to experiment data communication with cloud computing. What is cloud computing? According to Mache Creeger in the article “Cloud Computing: An Overview”, cloud computing refers a model of shift in the delivery of architecture of information services and data for economic reasons (Creeger, 2009). In this paper, I will present a brief overview of how cloud computing operate, the role of cloud computing in telecommunication industry, the advantages and challenges involved in its implementation.
How does cloud computing work? “Cloud” technically refers to the data center hardware and software used in providing a pay-as-you-go data service to the public. The term “private cloud”, on the other hand, is used by organizations to refer to their internal data centers (Armbrust, et al., 2010). Cloud computing can be divided into three types of services, namely software-as-a-service (SaaS) for WAN-enabled applications, platform-as-a-service (PaaS) for new applications, and infrastructure-as-a-service (IaaS) for computational and storage infrastructure (Creeger, 2009).

Sometimes, cloud is claimed to be nothing new in data services. Chris Rose, author of the article “A Break in The Cloud? The Reality of Cloud Computing”, suggests that cloud computing is the merging
