The so-called open source means opening up the source code of the software. Everyone can see the source code. Everyone can study the source code together and optimize and improve the software. More and more IT companies are open to open source. On the one hand, with excellent open source projects, there is no need to reinvent the wheel and can be used directly. On the other hand, their own companies have excellent self-research projects. In order to develop Changzhang can choose to open source the project so that more developers can participate and work together to improve the functionality of the software!

##Open source technology There is no doubt that it has been widely used in enterprises. Tech giants like Google and Microsoft also recognize the power of open source—as evidenced by Google Cloud’s recent partnerships with companies like MongoDB, redis Labs, Neo4j, and Confluent. But what do these companies think about open source? Why choose open source? What are their next steps for open source? Based on the above questions, Red Hat launched the “State of Enterprise Open Source” survey and released the survey report on April 16, 2019.
This report is the result of interviews with 950 IT leaders around the world, including the United States, United Kingdom, Latin America and the Asia-Pacific region. Understand the enterprise open source profile in different geographical regions.
The survey results show that the vast majority of the 950 respondents believe that open source is strategically important to the enterprise's overall infrastructure software strategy. In fact, more than 69% said it was very or extremely important.
