With the advent of the era of big data, the amount of global information data is growing explosively. The information data with rapid growth contain endless value. Big data information processing technology could help people discover knowledge and find rules from massive data, so as to create application value. But with the rapid development of social economy, the basic big data information processing technology has been unable to meet the higher and higher requirements of massive data processing. The emergence and development of cloud computing technology could provide a solution for big data information processing technology to meet the requirements of users for efficient processing of diversified massive data. The combination of artificial intelligence, big data and cloud computing is an inevitable trend of social development, and the research of big data information processing technology based on cloud computing becomes very important. Therefore, in order to improve the efficiency of information processing and maintain the accuracy of data, the existing classical data analysis algorithm model and cloud computing technology are combined in this paper. So some research is done on massive information processing technology based on big data and cloud computing, and a big data information processing method based on cloud computing and cloud computing is proposed.
