3. What’s Dubbo A high performance RPC framework Open Sourced Project Incubating at Apache Dubbo |ˈdʌbəʊ| is a java based RPC framework first open-sourced by Alibaba at 2011. Donated to Apache at 2017. A high performance RPC framework Based around the idea of defining a service, specifying the methods that can be called remotely with their parameters and return types. Beyond RPC: rich features for service governance Provides features for managing microservices: automatic service registration & discovery, fault tolerance, load balancing, traffic management… Production-tested and Proven At Scale Wildly adopted in internet companies and financial organizations in production for years, including Alibaba, JingDong, Kaola, Qunar, etc. dubbo.apache.org Copyright © 2018 The Apache Software Foundation 3

8. Current Status Dubbo in production If you are using Dubbo, please let us know: https://github.com/apache/incubator- dubbo/issues/1012 According to a survey recently. Dubbo user can be classified into three types: Internet companies, traditional companies embracing Internet, Companies providing Internet solutions. Dubbo have Apache PPMC from Dangdang, Qunar, Weidian and Alibaba. The Dubbo team plans to hold several meetups in Beijing, Shanghai, Shenzhen and Hangzhou. The ideas and speakers be discussed and selected from community. dubbo.apache.org Copyright © 2018 The Apache Software Foundation 8

9. Current Status 9 What have we done Upgrade dependencies to Meet requirements in the latest version: Spring, community: REST, Spring ZK, Hessian, Netty, Boot, Hessian, QOS, etc. Javassist、Validator, etc. Dependencies Community Docs and Website Releases Apache dubbo.apache.org enrichs Keep a relatively quick Donated to Apache, we with quick start, docs, release cycle, within 11 expect more developers and samples, community; month: organizations get involved in Rewrite docs using gitbook. 7 maintaince releases. 3 feature releases. dubbo.apache.org Copyright © 2018 The Apache Software Foundation the community.

10. Roadmap 01 Microservices: Lightweight, polyglot, REST, Spring Boot 02 Cloud Native: Spring Cloud, Service Mesh 03 Eco-System: build a one-stop ecosystem around Dubbo 04 Performance always comes first Challenges from large-scale clusters dubbo.apache.org Copyright © 2018 The Apache Software Foundation 10

11. Roadmap Dubbo Core Modularization Fault Tolerant Service Metadata Extremely large-scale clusters The communication layer and service management layer are highly coupled to each other. Metadata need classified by purpose: service maintenance, remote call, dynamic properties. Big pressure for Registry and User when stored in one URL. Traffic Routing Provides more routing policies: condition, script, enabling argument routing, zone- aware routing, canarying, and more. dubbo.apache.org Make Dubbo applications more stable by introducing short-circuit, isolation and flow- controland policies. Latency-aware LoadBalance policies. Meet the challenges of large scale clusters: service discovery, memory footprint and addresses, CPU, etc. Asynchronism Promote overall throughput and CPU utilization of distributed systems: aschronous API, Reactive, Stream Copyright © 2018 The Apache Software Foundation 11

15. Dubbo at Apache 15 Community Over Code Phase 1: Preparation Spend nearly 3 months in total. With 1 champion, Mentor IP Clearance First Release Proposal SGA Committer Discuss ICLA PMC 4 mentors. 1 week for proposal preparation, discussed and voted for 72h respectively, entered Incubating after 3 binding votes. Phase 2: Incubating This phase will take 8+ months. Asset transfer and community building are the most important part, Remember the Apache way: community over code Vote Meet Up Phase 3: Graduation We will pass the maturity evaluation and then vote for graduation.
