From the infrastructure to the cloud native application, all-round interpretation of Alibaba cloud's original and cutting-edge open-source projects

In 2020,Alibaba has not only realized the comprehensive cloud proto chemistry of the double 11 core system, but also become the largest and most powerful cloud native practice in the world, and realized the trinity of self-research, open source and business for the first time. On this basis, it opened the prelude of a highly competitive cloud native product family。 In order to let you have a more comprehensive understanding, we take this opportunity to sort out Alibaba’s three-tier three-dimensional structure from application layer to middleware to infrastructure.

Cloud original ecological value “focus”: OAM open application model and kubevela open application platform project

Nowadays, the rapid development of cloud native technology may make many people feel dazzled. But if we explore the essence of “cloud native”, it is not difficult to find that the original intention of this technology and concept is to make it easier for cloud developers to deliver and manage applications in a completely infrastructure independent way. With this original intention and appeal, kubernetes is the unified infrastructure layer Abstract project that shields the underlying concepts of “virtual machine” and “storage” for the platform team. However, the actual landing process tells us that there is still a huge gap between the cloud native “silk smooth” cloud application management and delivery experience only with the abstract infrastructure layer. Between kubernetes and users, there is still a layer of abstraction called “application layer”, which needs to be filled.

As this timeTop 10 new open source projects of China’s technical force in 2020The open application model (OAM) open application model, as well as its kubernetes implementation kubevela project, are the core projects of cloud native application layer jointly launched by Alibaba cloud and Microsoft and other cloud native community backbones. In the first mock exam, OAM is designed to provide a unified and end-user application definition model for any cloud infrastructure including Kubernetes, and KubeVela is the complete realization of this unified model on Kubernetes. So, for business developers, Kube Vela can be considered heroku of the cloud native community. For the platform team, kubevela can be regarded as an “application centric” and highly scalable kubernetes distribution due to its high scalability.

With OAM and Kube Vela, today’s platform engineers finally have a powerful tool that can encapsulate and abstract any kubernetes community capability into an end-user oriented application layer platform feature. As the users of this platform, business developers don’t need to know any knowledge about kubernetes. They can fully describe their code construction and application deployment details through the extremely simple application layer semantics, and then deliver them out with one click.

Cloud native middleware realizes the trinity of self research, open source and business, forming the best practice of microservice

Middleware is the cloud native from concept to implementation. K8s shields the differences of the underlying cloud infrastructure and becomes the operating system of microservice applications in the cloud native era. Between the cloud native operating system and the cloud native application, a layer of abstraction is needed to shield the underlying complexity downward, and provide convenient and reliable capabilities upward, so that the application can be deployed and operated on the new cloud infrastructure with low cost or even no cost, and enjoy the ability of cloud pay on demand and extreme capacity expansion. Alicloud native middleware takes such a responsibility.

Alibaba cloud’s native middleware was born within the Alibaba group, and formed the best practice in the field of microservices through the unique scenario of “double 11” Since the beginning of open source, Alibaba cloud native middleware has tried to make efforts in cloud products and open source, hoping to make the middleware system supporting Alibaba’s core business from closed to open and serve a wider range of users. In the following years, several well-known open source projects such as Dubbo, rocketmq, spring cloud Alibaba, Nacos, sentinel, Arthas, Seata, chaosblade and other well-known open source projects have been launched, and the best practices in the field of microservices have been formed. In just two years, spring cloud Alibaba graduated from the spring community and became the most popular spring cloud implementation for Chinese developers.

Luo Yi, one of the top ten outstanding contributors to open source, is the second generation leader of Dubbo, chairman of Apache Dubbo PMC, and head of spring cloud Alibaba。 In 2017, it was Luo Yi who started the open source operation of Dubbo and incubated Dubbo into a top-level Apache project in only 15 months. At present, the community has 18 PMC members, 57 committers, and 370 contributors. The community code proportion is more than 50%. Luo Yi contributes micro services through open source, which has a great influence in the cloud native field.
