With the development of bio-computer technology, more and more new types of storage media are coming into our sight. In 2007, Japanese scientists successfully used bacterial DNA to store data for millennia; we've also introduced crabs to computers and the use of bacteria to make hard drives, the idea of which is quite sci-fi. Recently, biological engineers and geneticists at the Harvard Institute of Harvard's Wyss Cato have successfully developed a new technology that can store about 700TB of data into 1 grams of DNA before using Dnah ...

In the field of telecommunications and it, a complete system consists of various kinds of basic physical resources and software resources, the basic physical resources provide computing, storage, network and other hardware capabilities, and all kinds of software constitute a variety of colorful applications. 　　These applications are developed by different manufacturers, based on different operating system platforms, using different software architectures, with different deployment patterns, the application of diversification will inevitably bring the complexity of software management. The software management described in this paper mainly refers to the lifecycle management of the software in the field, including the release of software, configuration management, distribution and deployment, patch management 、...
