下图说明了在V1版本中Contoso会议管理系统的关键体系架构。该应用程序由两个网站和三个限界上下文组成。基础设施包括Microsoft Azure SQL数据库(SQL Database)实例、事件存储和消息传递基础设施。
图后面的表列出了图中显示的构件(聚合、MVC控制器、读取模型生成器和数据访问对象)相互交换的所有消息。
备注：为了清晰，图中没有展示Handlers(把消息发送给领域对象的类，例如：OrderCommandHandler)。

标记*的这些事件仅用于使用事件源持久化聚合状态。
标记**的是ConferenceViewModelGenerator从SeatCreated和SeatUpdated事件创建的这些命令，这些事件在会议管理限界上下文中处理。
下面的列表概述了Contoso会议管理系统中的消息命名约定
所有事件在命名约定中都使用过去时。
所有命令都使用命令式命名约定。
所有的DTO都是名词。
该应用程序旨在部署到Microsoft Azure。在旅程的那个阶段，应用程序由两个角色组成，一个包含ASP.Net MVC Web应用程序的web角色和一个包含消息处理程序和领域对象的工作角色。应用程序在写端和读端都使用Azure SQL DataBase实例进行数据存储。订单(Order)和注册(Registrations)限界上下文现在使用事件存储在写端持久化状态。此事件存储是使用Azure table storage来实现的。应用程序使用Azure服务总线来提供其消息传递基础设施。
