topic introduction
" Dewu Blue-Green Release Evolution and Landing"
Director of Dewu Unified Framework & Distributed Scheduling - Song Jialin
With the continuous growth of business, the scale of enterprise microservices will also become larger and larger. How to efficiently realize the seamless update and switching of microservice versions is a huge challenge. Blue-green release is one of the solutions. By deploying two independent production environments, seamless update and rollback can be achieved to ensure the continuity of user experience.
This sharing will introduce the principles and benefits of blue-green release in detail, and discuss in depth how to create and manage two environments, and how to control traffic ratio and traffic stickiness. With blue-green releases, you can reduce risk, speed up releases, and achieve continuous delivery. Of course, the implementation of the blue-green release is not all smooth sailing. In the sharing, we will also discuss the challenges that may be encountered in practice and provide solutions.
" Istio -Based Service Mesh Landing Practice"
Senior Architect of Xinye Technology-Xu Yuqiang
In recent years, cloud native technology has developed rapidly, and Service Mesh is called the next generation of microservices, or directly called microservices 2.0. As one of the best, istio has become the de facto standard of Service Mesh. isito uses a unified sidecar to realize the unified governance of heterogeneous languages and frameworks, provides capabilities such as traffic management, observability, and security, and overcomes the pain of upgrading in traditional microservice governance.
This sharing will show how to migrate from traditional microservices to the istio system, what business value istio has brought from its implementation, and the record of "stepping on the pit" in the process of istio's promotion.
"Apache Pulsar--Financial Grade Cloud Native Messaging Platform "
Apache Member, Apache Pulsar PMC member, StreamNative co-founder - Zhai Jia
Apache Pulsar is an open source next-generation Pub/Sub messaging system. Through special design and abstraction, Pulsar supports two message consumption modes, Streaming and Queueing, and maintains the high performance of Streaming mode and the flexibility of Queueing mode. The scene has undergone a large-scale stress test.
While ensuring the performance and throughput of the big data message system, Pulsar provides more enterprise-level features, including convenient operation and maintenance and expansion, flexible message model, multi-language API, multi-tenant, remote multiple backup, and strong Persistence and consistency, etc., solve some shortcomings of existing open source message systems. For example, Pulsar provides a more elegant solution to the difficult problems of strong consistency and persistence in message systems; Pulsar easily resolves the problems of expansion and operation and maintenance in other message systems through a Segment-based storage architecture. problem.
" Dewu DLB Evolution Road"
Dewu middleware technical expert-Chen Hao
