解决方案从构建一个安全的PostgreSQL环境开始，针对生产工作负载调整数据库，构建一个避免单点故障的高可用性策略，使用连接池扩展PostgreSQL以避免服务器资源的过度使用，以及加载Balancing在可用的备用副本之间进行读取，以有效地利用所有数据库服务器的计算能力。
我们将发布一系列的博客文章来扩展下面的每个主题。当我们展示整个项目时，本次网络研讨会将更加详细。
博客中涉及的主题以及网络研讨会上演示的主题包括：
保护PostgreSQL数据库集群
PostgreSQL中的高可用性
准备PostgreSQL备份策略和可用工具
使用连接池和负载平衡器缩放PostgreSQL
详细登录PostgreSQL以及您可用的工具和扩展
监控PostgreSQL环境
我们将在45分钟的网络研讨会中指导您完成整个过程，向您展示我们取得的成果以及我们的解决方案在实践中的工作方式。在本次网络研讨会期间，您将看到一个简单的Web应用程序正常运行，然后演示当我们杀死主机、从设置中删除连接池以及添加另一个副本以共享读取负载时会发生什么。
