Cloud computing is also one of the most discussed fields in advanced IT in recent years and is
extremely closely related to Mobile IT. Cloud computing can contribute to cost reductions and profit
increase with minimizing IT assets and promoting application standardization. Many Mobile IT
applications operate with Cloud-based software that can be used as SaaS. Other existing Cloud
computing formats include Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). Each of
these formats has architectures that directly affect organizational EA (Khan & Gangavarapu 2009). IT
applications that run on these Cloud computing formats are composed of the above Web services with
the design approach of SOA. However, "current EA methods do not take into account handling the
complexity of dynamic strategic changes in corporations nor dynamic changes in IT trends" (Alwadain
et al. 2014), and EA cannot cope with the great changes in leading IT trends due to recent
developments in Cloud computing. It has been indicated that "current IT trends such as Cloud
computing are a challenge for EA" (McKendrick 2010).
