具有状态复制的软件服务的配置
Failover of Software Services with State Replication
摘要：
计算系统正变得越来越复杂，并在人类活动的所有部门承担越来越多的责任。应用程序不再在单个计算机上本地运行。今天的许多应用程序都是作为分布式系统构建的;不同计算机上的服务相互通信。分布式系统到处都是。互联网是最著名的分布式系统之一，今天几乎每个人都在使用它。很明显，我们越来越依赖计算机服务。许多人希望即使在晚上也能在互联网上购买衣服或电子设备等物品。预计计算机将每周7天、每天24小时运作。停机时间，即使是维护，也不再是可以接受的。
英文摘要：
Computing systems are becoming more and more complex and assuming more and more responsibilities in all sectors of human activity. Applications do not run locally on a single computer any more. A lot of today's applications are built as distributed system; with services on different computers communicating with each other. Distributed systems arise everywhere. The Internet is one of the best-known distributed systems and used by nearly everyone today. It is obvious that we are more and more dependent on computer services. Many people expect to be able to buy things like clothing or electronic equipment even at night on the Internet. Computers are expected to be operational and available 7 days a week, 24 hours a day. Downtime, even for maintenance, is no longer acceptable.
