Over the last two decades, the role of information technology in organizations has changed from primarily a supportive and transactional function to being an essential prerequisite for strategic value generation. The organizations based their operational services through its Information Systems (IS) that need to be managed, controlled and monitored constantly. IT governance (ITG), i.e. the way ...

Most of the services viewed in context to grid and cloud computing are mostly confined to services that are available for intellectual purposes. The grid or cloud computing are large scale distributed systems. The essence of large scale distribution can only be realized if the services are rendered to common man. The only organization which has exposure to almost every single resident is the re...

Service-Oriented Architecture (SOA) is a paradigm used by organizations to reduce costs and foster agility through reuse of assets and an increase of alignment between business and IT. To achieve these benefits, a governance model is vital to ensure that technical actions and decisions of IT departments are aligned to organizations’ business goals and requirements. There are several proposals o...

Service-Oriented Architecture (SOA) adoption is known as an evolutionary process. In this process of adoption, a number of areas in an organization are affected. However, there are a limited number of researches that focus on the effects of SOA adoption in an organization. This study investigated the significant organizational factors affected by SOA adoption during the last six years. The stud...

Security certification assesses the security posture of a software system to verify its compliance with diverse, pre-specified security controls identified by guidelines from NIST and the US Department of Defense. Service-oriented architectures (SOA) are difficult to certify because they require compliance verification over a mix of local, global, and interaction criteria dictated by the polici...

Service Oriented Architecture (SOA) technology enables composition of large and complex computational units out of the available atomic services. Implementation of SOA brings about challenges which include service discovery, service interaction, service composition, robustness, quality of service, security, etc. These challenges are mainly due to the dynamic nature of SOA. SOAmay often need to ...

Cloud computing is a business concept that delivers technology “as a service”. Its lower cost of operation is the main economic driver for consumers and enterprises. The major obstruction to its adoption is security and governance risks inherent in its transnational nature. These risks are associated with relative change of governance level within the cloud service layers during the relationshi...

In the past few years, many frameworks and standards have been developed to cover different aspects of IT to provide best practices, such as COBIT, ITIL, CMMI, ISO/IEC 20000, ISO/IEC 38500 and ISO/ IEC 27000, and improve IT governance and IT service management in organizations. This research presents how self-assessments for IT standards improve significantly the strategic and tactical evaluati...
