清楚一切可能性的障碍 On unplugging
所有这一切都依赖于数据库服务器和管理连接池的中间件的可伸缩性。
All this depends on both the scalability of the database server and the middleware managing the connection pool.
不要误会,您当然需要了解关于速度,性能,可用性,应用平台,网络等相关的一切,但这并非可扩展性的定义。
You still need to know all about speed, performance, HA technology, application platform, network, etc. But that is not the definition of scalability.
您需要确保一切无状态,才能获得更好的可伸缩性。
You need to keep things stateless to make them scale better.
