In CC, there are promoting many services that provided for The CoP with taking care by themselves in term of licensing, agreements, and many other things in managing hardware and software. These services are including Platform as a Service (PaaS), Infrastructure as Service (laaS), Storage as a Service (DaaS), and Software as a Service (SaaS) [2,4,5,7]. The connection of those services in CC is shown in Figure 1.

METHODOLOGY
In order to formulate the model of KMS for facilitating the knowledge as a service (KaaS) in a CC environment, there are several steps as followed: Figure 2.
