Cloud computing, an internet-based computing technology, is a web-based software service of calling and using programs placed in the internet utility data server via computer or mobile phone according to user's need. In this thesis, web-based cloud computing technology will be applied to livestock farms to develop livestock monitoring and disease forecasting system at existing livestock or apply to system that has already been developed. The proposed system uses column-oriented database Hadoop HBase to store and manage livestock environment & livestock database and implements livestock environment monitoring and facilities control through the parallel processing via MapReduce model. Since the proposed system is web-based, there is no server development cost when internet is connected, and livestock data is managed at the main server to efficiently and convenient manage livestock.
