The Apache Software Foundation (ASF) incubator passed the incubation graduation vote for the Apache EventMesh project on February 15, 2023. On March 22, 2023, the Board of Directors of the Apache Software Foundation approved the graduation of Apache EventMesh and became an Apache Top Level Project (TLP).

one,About Apache EventMesh

Apache EventMesh is a versatile platform that combines event-driven and serverless architectures to simplify event-driven application development in complex distributed systems.Its main goal is to enable seamless, serverless, event-driven functionality for various components and applications using the publish-subscribe pattern. Often referred to as “EDA plus Serverless” and “Eventing as Infrastructure”, EventMesh provides a highly scalable and reliable event infrastructure that can efficiently handle massive event traffic.

EventMesh is the world’s first EDA+Serverless to fill the gap in “Eventing as An Infrastructure” in the open source field. It is the world’s first financial industry to enter the incubation of the Apache Foundation. It is included in the Landscape of the Linux CNCF Foundation and is also a trusted open source community.With the world’s first go-engine implementation that complies with the CNCF Serverless workflow standard, it has attracted widespread attention in the Serverless field. The original message-based request-reply synchronous communication mode is integrated by Apache star projects RocketMQ and Dubbo, and widely serves a large number of enterprises and business scenarios.

Apache EventMesh is designed to be flexible and can be customized to support different messaging protocols and use cases. This makes it suitable for a wide range of applications and systems ranging from finance, telecommunications and supermarkets to manufacturing, cloud infrastructure and more. Many companies already use EventMesh as an event platform. At present, it has been implemented in large enterprises such as Huawei Cloud, Tencent, Zhengcai Cloud, Yonghui Supermarket, and Linghang Power. Among them, the Huawei Cloud EventGrid product is completely based on EventMesh, serving a large number of customers on Huawei Cloud.

During the two-year incubation period, the PPMC members of the project are mainly from domestic first-tier companies such as Tencent, Huawei, Ali, and Didi, as well as many foreign members. The community has more than 260 active contributors from more than 10 regions and countries around the world. The external code contribution exceeds 400,000 lines. Apache EventMesh has released 7 Apache versions led by community developers, and an average version will be released in about three months; 5 new PPMC members and 20 Committers have been added, from different companies and organizations. The indicators of the Apache EventMesh community are developing well, and the project has matured. Apache EventMesh successfully passed the graduation evaluation and voting of the Apache Incubator Project Management Committee, and was approved by the ASF Board of Directors. After graduation, it was promoted to the top project of the Apache Foundation.

Apache EventMesh is designed as a new generation of serverless middleware for building event-driven applications. It decouples software infrastructure through built-in loosely coupled modular architecture and event-driven architecture. Different from the classic message architecture, Apache EventMesh provides a series of innovative combination orchestration, reliable traceability, efficient delivery, full link tracking and other agile application building capabilities. It is a great honor to be the chief mentor of the project, to witness the continuous development and growth of the community, to understand and practice the great “Apache way”. Today’s graduation is a very good start, and I look forward to the better and better development of the community, come on.

Organizations are more and more dependent on the data to drive their business. Streaming integration of the data is a critical piece of the data platform. Apache EventMesh is the glue between the different layers. It implements the CloudEvents specification, smoothly working with transports (gRPC ), connectors (Apache Kafka, Apache Pulsar, …), and controllers (ETCD, Apache Zookeeper). We can see EventMesh as a new ESB architecture, breaking the centralized approach of traditional ESB solutions. As EventMesh provides a full architecture, you can be ready in a minute, focusing on your event-driven applications. Thanks to EventMesh, your event integration layer is scalable, secure and reliable. After a good incubation period where the EventMesh community grew up, it’s great to see EventMesh graduated. We are sure it will attract more and more users and contributors.

With the development of cloud native technology, event-driven (EDA) architecture has received extensive attention again. Apache EventMesh fills the gap in open source event-driven basic services. EventMesh’s multiple communication protocols, CloudEvents specification, Mesh architecture, and powerful observability features are all very suitable for enterprise implementation. With the help of EventMesh, Geely has realized a decentralized event platform, realized cross-cloud and cross-continent event integration capabilities, and greatly reduced the management cost of event integration. Expect the Apache EventMesh ecology to become more and more successful.
