The rapid evolution in computing hardware and diverse software development accelerate cloud computing which makes it possible to develop a software in a cost-effective way. This course deals with the concept of cloud computing and associated basic underlying technologies first. Then three representative types of cloud SW development and environments,  IaaS, Paas, and SaaS will be explained. Students will have a chance to try SW developments over major cloud services to know its pros and cons from experience. They are expected to develop an end to end service which is implemented by data collection, database setup, data processing, data visualization, and various APIs for specific tasks.
