企业官网建设流程全解析

一：核心内容介绍

1：核心主干

2：分布式配套

日志系统+指标监控+链路追踪+消息处理

3：服务架构演变图

二：基础架构设计

以车险承保为例，大致模块功能如下：

历史询价、真实下单、险种计算、验车、核保、支付、承保等。

1：单体架构

单体架构优缺点：

优点：开发 / 部署 / 运维简单、本地事务简单

缺点：代码耦合严重、项目臃肿、不抗高并发、单点故障风险高

2：集群架构

优势：抗并发量显著提升。

缺点：

1：模块升级需要升级全部

2：引入新模块语言+技术栈都受限制，项目十分臃肿。

3：分布式和微服务

以上模块拆分成多个模块，多个模块之间独立部署。随之数据库也进行拆分。

优点：

1：独立部署、数据隔离、语言无关。完全自治。

2：

三：创建微服务项目

1：环境准备

2：项目工程结构图

3：项目构建
