服务等级协议(SLA)的重要性 ID:54.223.194

基本问题是“哪个服务器集群服务提供商是我的应用程序的最佳选择?”很少有北京电信服务器集群提供商甚至接近为其环境中的应用程序性能提供服务级别协议(SLA)。然而，这对决策过程至关重要。如果应用程序的运行速度比目前慢，则此迁移决策可能会影响组织的业务。如果需要添加更多容量、功率、资源来托管它，则成本就会上升。

因此，其起点是分析计划迁移的应用程序的工作负载行为和性能特征。在服务器集群服务提供商选择过程开始之前，了解应用程序如何执行以及它们正在使用哪些规定至关重要。每个应用程序都有一个单独的工作负载配置文件，根据环境的不同，它们的行为会有所不同。在查看应用程序工作负载时，需要随着时间的推移收集资源需求的高峰和低谷，以获得真正的洞察力。例如，周一上午8点可能需要不同的资源，而周四下午2点可能需要不同的资源。季节性也需要考虑在内，例如探索在年、月、周、日的不同时间是否有更多的吞吐量。

除了应用程序的性能之外，还需要了解其依赖性。如果应用程序正在访问不会在云中托管的其他资源，或者由其他提供商管理，则会影响性能和成本。

在托管应用程序时，每个服务器集群提供商的云平台都有优势和劣势。应该密切关注潜在的供应商。如果选择了错误的服务，业务可能会面临风险。每个应用程序工作负载都需要针对新环境进行测试，以确保与当前性能相比提供更好或至少相同的服务。一项企业战略小组研究发现，57%迁移应用程序或迁移到SaaS(软件即服务)的组织54.223.194.64由于性能令人失望或成本上升而将数据和/或应用程序内部转移。其他分析人士也发现了类似的统计数据。这主要是由于迁移之前缺乏计划或计划不周造成的。
