In a word, open source refers to the software or design body whose source code or design can be used, modified and released by the public
Android is the most familiar open source software for the public. I believe that non Apple smartphone users must use Android every day, and it is also one of the most influential open source software. Without Android's open source, I believe that there are not so many mobile phone manufacturers and the rise of mobile Internet today
If only from the perspective of ecology, Apple's ecology is also very open, and now they have launched open source swift. In this respect, both are the same, but the open source and open methods are different
linux is undoubtedly the most successful open source software. No matter from the perspective of its current ecological construction or the evaluation of the instry, the foundation of today's cloud computing also depends on the contribution and cornerstone of Linux. Of course, openstack, Hadoop and spark are also very successful. These open source projects belong to the underlying technology, supporting the development of big data and cloud computing today
open source does not mean free. Open source only means that we have made a good thing and opened it to everyone. The purpose is to hope that everyone can use it more and feed back the problems or improvement methods in the process of using it, so as to make the whole open source project progress faster and better share it with more people in need, At present, Linux, Hadoop, spark and so on all do this. But many times there is a strong business background behind open source
there are commercial companies behind the relatively large open source projects. If there is no commercial company behind a successful open source project, it is unhealthy. We need the complementary symmetry between open source and business to promote the continuous progress of the whole community and technology
