Abstract
The concept of cloud-provided IT solutions has changed from being an emerging technology to a reality that most large corporations have adopted or are planing to adopt. Accordingly, many companies have already moved some of their applications or a portion of their infrastructure to the cloud. This adoption varies between the different categories of cloud offerings: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). This paper will discuss the challenges of cloud adoption from the three perspectives of successful organizations: people, process, and technology.
Highlights
Cloud computing has recently emerged as an effective technology that enables businesses to host and deliver services over the Internet
The operational cost of delivery, maintenance, and support of cloud services is generally lower than on-premises hosted services, which results in reduced Total Cost of Ownership (TCO)
Many companies find themselves locked to the technology provided by a single Cloud Service Provider (CSP) or locked in a long-term contract that makes the situation extremely costly and difficult to migrate to an alternative cloud solution providers (CSPs), which offers more attractive services
Summary
Moving computing services to the cloud helps corporations to achieve increased business agility and flexibility. Cloud services operate on a subscription model, which relieves corporations from the challenge of long term capital planning. According to Nasdaq Cloud Computing: Industry Report and Investment Case [3], organizations may incur 30% in cost savings if they were to switch from an on-premises infrastructure This paper sheds light on these issues and discuss various challenges of cloud adoption in large corporations. Examples of these challenges are: business-case justification, vendor lock-in, data privacy and security, integration with on-premises systems in hybrid architecture scenarios, and business transformation. Additional challenges are lessons learned from the literature and analyzing the experience of other companies during our cloud adoption journey [4]
