Internet is now becoming increasingly popular, and there is more and more data generated on the Internet. With respect to the storage problems of large amount of data, at present, the three most commonly used storage methods are open systemÂs direct storage, network attached storage and storage area network. With the development of network, there is the emergence of a new type of storage technology, which is the storage technology for large data volume based on cloud computing. Technically in cloud computing, the reach is based hadoop and virtualization technology, focusing on the storage technology for large data volume of cloud computing. First, we have a preliminary idea on how to access the large amount of data based on cloud computing. Secondly, we need to select the algorithm and model, and we choose the MapReduce model in this regard, and conduct the corresponding programming based on this model, so as to achieve processing of large data according to the Hadoop framework. Finally, according to the above ideas, we have completed storing a large amount of data based on the cloud computing. At last, we make outlook and summary for the storage technology for large data volume based on cloud computing. As the next generation of computing model, cloud computing is widely used in many areas of scientific computing and commercial computing. But it is still in its infancy, and there are still a lot of unclear problems to be solved in the field of cloud computing and there are still many open questions requiring further research and exploration.
