    • Information and Communications Technology and Policy. 2020, 46(5): 38-44.
    • Abstract ( 358 ) 　　
    • As open source is becoming more and more important, data analysis that is relatively complete and can be deduced repeatedly based on global open source big data is particularly important. In this work, we use the GitHub trace data of 2019 with the total number of 546 million logs for analysis. It aims to observe the current status, progress,and trends of open source worldwide from the perspective of data by analyzing the developer behavior logs of the entire GitHub. In addition to showing the full picture of the current open source world, evolutionary characteristics and future challenges, we pay special attention to the performance of Chinese developers and enterprise organizations in the entire open source industry.

    • Research on message queue cloud service based on open source message queue technology
    • ZHENG Li, CHEN Yili, LIU Ruming, ZHENG Danyang
    • Information and Communications Technology and Policy. 2020, 46(5): 52-56.
    • Abstract ( 192 ) 　　
    • With the continuous growth of the scale of Internet application software, distributed architecture has become the mainstream mode of application development. Message queuing solves the communication problems between distributed applications. The promotion of open source has made message queuing a hot technology with rapid development. At the same time, after more than ten years of development, cloud computing has gradually penetrated from providing IT infrastructure to application development. Domestic mainstream cloud service providers have launched their own message queue cloud services based on open source message queue technology. How to evaluate the functions of these cloud products and performance, to provide users with objective and accurate references, thereby to promote the active development of the cloud computing market, is an important issue that needs to be resolved urgently. This article introduces the current mainstream open source message queue products, then analyzes and studies the characteristics of cloud-based message queuing products, and finally analyzes the performance testing indicators of message queuing cloud services to provide reference opinions for enterprise and individual user selection.

    • 5G + Cloud + AI empowers new digital infrastructure
    • YANG Yang
    • Information and Communications Technology and Policy. 2020, 46(5): 67-70.
    • Abstract ( 388 ) 　　
    • Different from traditional infrastructure, “new infrastructure” refers to the infrastructure construction focused on the technology side, mainly including 5G base station construction, UHV, intercity high-speed railway and urban rail transportation, new energy vehicle charging piles, big data centers, Artificial Intelligence and Industrial Internet.The seven major areas of the Industrial Internet involve many industrial chains. As the downward pressure on the economy has increased, many local governments and enterprises have also increased their financial pressures, and they have begun to promote “new infrastructure. ” The strategic significance of digital “new infrastructure” is analyzed, the dilemma of traditional industry digitization is explained, the relationship between 5G, cloud computing, and AI in “new infrastructure” is discussed, and the early application of 5G + cloud + AI is analyzed.
