Abstract: Since the year 2000, Enterprise Architecture has been the object of focus as a method for
promoting an IT architecture that establishes consistency between corporate business and IT strategies, and it has
been applied mostly in global corporations. However, with the recent progress in Mobile IT technology and Cloud
computing towards the era of Digital IT, in the IT systems of global corporations, the shift from conventional on
premise server-based IT systems to Cloud computing, such as Software as a Service (SaaS), Hybrid Cloud, and
connected Mobile IT systems as core elements of Digital IT, has become more pronounced. In promoting
Enterprise Architecture, EA based upon an approach compatible to the cutting-edge IT technologies of Mobile
IT/Cloud computing will be required by global corporations. This paper elucidates key points for EA methods to
respond to the cutting-edge IT technology that will be required in the future by conducting a comparative analysis
of the support environments of Mobile IT elements and related Cloud computing technology in each EA
framework currently used widely in many global corporations.
