Through the high costs of utilizing and updating old knowledge management systems along with their related issues and problems, Knowledge management systems that based on cloud computing becomes a clear solution for the exchange of knowledge and being used effectively in organizations. Knowledge as a service (KaaS) is an emerging concept that integrates knowledge management (KM), which include a knowledge organization, and knowledge markets. KaaS contains programs that provide content-based (data, information, knowledge) as organizational outputs (e.g., advice, answers, facilitation), to meet personal or external user who wants or needs. Knowledge as a services (KaaS) programs are delivered through the knowledge markets as a cloud computing (CC) environment. In ensuring the services that will be delivered to the right Community of Practice (CoP) at the right time in a proper manner, there is a need of a system called knowledge management system (KMS), so that the KaaS can be well managed in a proper form by using the Knowledge Management life cycle processes.
