4. METHODOLOGY
Lately, developers have developed various learning
management systems, such as learning management systems
that cater for the needs of inexperienced users [16] however,
those developed learning management systems have a lot of
problems. For example, it is difficult to manage single
distributed management on the internet and cover the needs
of all users at the same time. [17] For this reason, we have to
develop a learning management system with our own
programs. But, we cannot meet the demand of users due to
the lack of distributed learning material. The most important
issue is the high cost of development as stated earlier. Adding
or expanding the system also requires more investment. Most
of the cost problems come from the needs of service and
maintenance. So, to solve this problem, we present a new
model for learning management systems by applying Cloud
computing with Web services.
