The military of the Republic of South Korea applies infrastructure as a service (IaaS) cloud-computing technology and applications distributed nationwide are transferred to two defense-integrated data centers (DIDCs). However, to improve the quality of the military information service provided by the DIDCs, it is crucial to expand the cloud-computing service from IaaS to the software as a service (SaaS) level. Owing to the in-house planning, development and operation of military applications by the Ministry of National Defense and each military force, these organizations operate several applications that are similar and redundant. Accordingly, SaaS can reduce the costs of IT services and management overhead by eliminating similar and redundant applications and integrating them into common services. In this study, a military service framework (MSF) was designed based on the criteria of business functions and service targets. The MSF was applied to applications currently in operation to create a current military SaaS portfolio, whereas the future military SaaS portfolio was restructured by identifying common services within and between organizations and throughout the military. Consequently, 369 future military SaaS portfolios were created, representing a 36% decrease realized by integrating similar and redundant systems out of 580 applications.
