1.1 Introduction
Cloud computing is defined as a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources such as networks, servers, storage, applications, and services that can be rapidly provisioned and released with minimal management effort or service provider interaction (Mell & Grance, 2011). It represents a significant shift in the way Information Technology (IT) services are delivered and consumed, as it allows organizations to access computing resources over the internet instead of relying solely on local infrastructure or traditional IT outsourcing arrangements.
In the context of modern business operations, cloud computing has become a strategic approach for improving efficiency, reducing operational costs, and enhancing flexibility in IT service delivery. Unlike traditional IT outsourcing models that require heavy investment in physical infrastructure, cloud computing uses a pay-as-you-go model that allows organizations to scale resources based on demand. This flexibility has made it an attractive alternative for organizations seeking to optimize performance while minimizing capital expenditure (Marston et al., 2011).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Limitation of the study and Definition of technical terms.
1.2 Background of Study
Cloud computing has emerged as a transformative innovation in Information Technology (IT), fundamentally changing how computing resources are delivered, accessed, and managed across organizations. According to Mell and Grance, cloud computing is defined as a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources such as networks, servers, storage, applications, and services that can be rapidly provisioned and released with minimal management effort or service provider interaction (Mell & Grance, 2011). The evolution of cloud computing is closely linked to the growing need for efficient IT outsourcing solutions. Traditionally, organizations relied on in-house IT departments or outsourced their IT functions to third-party vendors who managed physical servers, data centers, and software applications. According to Marston et al., they stated that traditional IT outsourcing models often involve high capital expenditure, long deployment cycles, and limited scalability, which restrict organizational agility and innovation (Marston et al., 2011).
In response to these challenges, cloud computing has introduced a more efficient model of IT outsourcing that allows organizations to access computing resources as services rather than owning and maintaining physical infrastructure. According to Armbrust et al., they asserted that cloud computing represents a shift from ownership-based computing to service-based computing, where users access resources on-demand and pay only for what they use (Armbrust et al., 2010). In many sectors, organizations are increasingly adopting cloud-based solutions such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). According to Buyya et al., they contended that these service models provide flexible access to computing resources, development platforms, and software applications without requiring heavy investment in physical infrastructure (Buyya et al., 2009). This flexibility has made cloud computing an attractive alternative for businesses seeking cost-effective IT outsourcing solutions.
The background of cloud computing is also rooted in the rapid expansion of internet technologies and the increasing demand for data storage, processing power, and real-time information access. Organizations today generate massive volumes of data that require efficient management systems capable of scaling quickly. According to Armbrust et al., they affirmed that cloud computing addresses the challenge of large-scale data management by offering virtually unlimited storage and processing capabilities through distributed computing systems (Armbrust et al., 2010). According to Mell and Grance, they reported that concerns such as data security, privacy risks, regulatory compliance, and dependency on internet connectivity continue to affect organizational willingness to fully migrate to cloud-based systems (Mell & Grance, 2011).
On the other hand, cloud computing continues to gain global acceptance due to its ability to improve operational efficiency, reduce costs, and enhance service delivery. According to Buyya et al., they asserted that cloud computing is increasingly being recognized as the fifth utility alongside water, electricity, gas, and telephony because of its essential role in modern digital infrastructure (Buyya et al., 2009).
In developing countries, cloud computing presents both opportunities and challenges. While it offers a cost-effective alternative to traditional IT outsourcing, issues such as inadequate broadband infrastructure, limited technical expertise, and concerns about data sovereignty continue to affect adoption rates. Organizations are therefore required to carefully evaluate both the benefits and risks associated with cloud-based IT outsourcing before full implementation. This study is set against the backdrop of the growing global shift from traditional Information Technology outsourcing models.
1.3 Statement of Problem
Investigation revealed that many organizations experience delays in deploying applications, storing and processing data, and responding to increasing customer demands because traditional systems are not designed to scale effectively. In many cases, organizations invest heavily in IT resources that are either underutilized or become obsolete within a short period (Marston et al., 2011). On the other hand, cloud computing has emerged as a modern approach that provides shared computing resources, remote data storage, improved scalability, and cost-effective IT services through internet-based platforms (Buyya et al., 2009).
Furthermore, the absence of proper policies, insufficient training of IT personnel, and resistance to technological change have limited the successful implementation of cloud computing solutions in many organizations. As a result, several organizations continue to experience inefficiency in service delivery, increased operational costs, poor system performance, and reduced competitive advantage in the digital economy.
It is against this backdrop that this study seeks to examine cloud computing as a better means of Information Technology outsource.
