The fastest way to store a computer system is the ram traditionally used primarily as memory. As the access performance of the hard drive has deteriorated over the years, and the cost of RAM has been decreasing, many researchers have been exploring how to replace the hard disk with memory in recent years. As early as the 1980, David DeWitt and Garcia-molina and so on published a main memory database paper. Steven Robbins's article points out that the Turing Prize winner, Jim Gray, is more explicit about the idea that "memory will be a hard drive and the hard drive will become a tape."

"Geographic Information System (GIS) platform software localization rate of the next target is 70%, the iron also needs its own hard, geographical information enterprises must continue to increase the investment in innovation, continuous upgrading and improve products, in order to be worthy of the support of domestic software." 　　Song, deputy director of the National Surveying and Mapping Geographic Information Bureau, said at the 2014 China Geographic Information Industry conference that GIS platform software is the technical core of geo-information industry, the commanding point of technological innovation and industrial development, and the key to ensure National Geographic information security.

The industry defines cloud computing in a variety of ways, but, as seen from several well-known cloud computing models, storage is a fundamental support component that is not in any way open, and cloud storage, as one of the branches of cloud computing services, mentions storage as the primary location.     At the same time, there are not many vendors who can solve storage problems well in the underlying architecture, and storage is facing a number of bottlenecks to achieve cloud computing. At an Intel organized media training camp, Intel (China) Limited server platform Product Manager ...

If all goes according to plan, Red Hat will be the first Open-source software vendor to make more than 1 billion dollars a yearly income. This will be a turning point for the open source software community. The open source community has always believed that their community-based approach to development is feasible, even superior, and alternative to traditional software development methods. ' I think we're going to see a fundamental shift in where technological innovation will take place, from the labs of several software companies to the huge open source soft ..., ' said Red Hat CEO Jim Whitehest Jim Whitehurst.
