Introduction:Come and win big prizes~
In 2021, copu, the China open source software promotion alliance, took the lead in publishing the 2021 blue book on the development of open source in China, covering the overall situation analysis, developer analysis, project analysis and field cases of global open source, and drawing a “open source digital ecological map”. Let’s have a comprehensive view of the Chinese power in the field of open source.
The report states that:
- Domestic enterprisesAli ranked first in open source activity, some indicators are even the sum of other companies, and they are also doing well in terms of community / openness;
- Dubbo、RocketMQThe two cloud native middleware open source projects are in the project of Apache Software Foundation in ChinaOpen source quadrant first matrix(Globalization + influence);
- Chinese Top 20Item list Nacos、SeataTwo middleware open source projects are on the list.
This year, 14 open source projects of Alibaba cloud’s original open source family joined a series of open source activities in Colleges and universities supported by the open source software supply chain lighting plan of the Institute of software of the Chinese Academy of Sciences – Summer 2021. Official website:_https://summer.iscas.ac.cn/_

In the era of cloud computing, message communication has become a key link of modern data-driven architecture. Message middleware can connect data sources, data processing engines and applications. However, globally, there are still two major problems in the message field: one is the lack of supplier neutral industry standards, which leads to the high complexity and incompatibility of various message middleware, resulting in the company’s product inefficiency, confusion and supplier locking. Second, the existing scheme framework can not well adapt to the cloud architecture, that is, the non cloud native architecture, so it can not effectively provide technical support for emerging business needs such as big data, stream computing and the Internet of things. Openmessaging abandons the burden of history and takes the battle light, hoping to solve these disadvantages. In addition to the standards that can link across platforms, languages, products and clouds, openmessaging will provide cloud native capabilities, face cloud computing and hybrid Cloud Architecture, realize the seamless migration of multi cloud platforms, and is committed to providing one-stop solutions in the fields of finance, e-commerce, IOT and big data.
