modular components: • A pluggable ordering service establishes consensus on the order of transactions and then broadcasts blocks to peers. • A pluggable membership service provider is responsible for associating network with cryptographic identities. • An optional peer-to-peer gossip service disseminates the blocks output by ordering service to other peers. • Smart contracts (“chaincode”) run within a container first phase also eliminates any non-determinism, as inconsistent results can be filtered out before ordering. Because we have eliminated non-determinism, Fabric is the first blockchain technology that enables

Service Mesh Meetup #5 广州站 ## 唯品会Service Mesh的实践分享 郑德惠 2019.1.6 • 唯品会内部Service Mesh的演进 • 与Istio的区别 • 实践中踩过的坑 • 今年规划（Roadmap） ## 内部Service Mesh的演进 ### 服务化体系1.0 Service Registry Service Config 服务路由网络传输 • OSP (Open Service Platform) • Thrift over Netty • 基于Java语法的DSL • Zookeeper 服务元数据下发 - 胖客户端 • 基本服务治理功能 ## 缺点 • 语言单一 · 升级困难 • 复杂代码嵌入对客户端进程影响大 ### 服务化体系2.0 - Service Mesh雏形 ![Image](/ 尽量减少外部组件依赖。业务/运维总会有各种特殊的需求，依赖外部组件会给自定义需求带来障碍。 - 保持客户端选择proxy的自由度和灵活性，在我们的实践中好处大于坏处 #### 胖客户端 vs. service mesh vs. cluster ||胖客户端|Sidecar（物理机）Daemonset（云）|Cluster（HTTP）| |---|---|---|---| |接入难度|容易。打入依
