使用Windows Azure Service Management REST API进行伸缩性管理
Nevin (Naiwen) Dong
以自定义的方式对Windows Azure资源进行控制,例如基于预设条件或者基于性能监控结果的自动伸缩管理,将更有效地对Azure资源/服务进行管理。Windows Azure SDK提供了全套API,特别是服务管理的REST API方式,使得这一想法成为可能。 对于Windows Azure Service Management REST API,可以参考以下网址: http://msdn.microsoft.com/en-us/library/ee460799.aspx Windows Azure Service Management REST API的功能支持,与通过其他方式,例如通过Windows...

使用Windows Azure Management Portal和Windows Azure PowerShell 命令行进行伸缩性管理
Nevin (Naiwen) Dong
在Windows Azure中开发部署云应用,或者将现有应用迁移到Windows Azure云平台,伸缩性是一个重要的考虑因素,直接关系到云应用资源的按需使用及产生的相关成本。 伸缩性与应用场景及所使用的云资源密切相关,例如,某些商务网站,当业务请求负荷迅猛增加、超出预设的容量能力上限时,应考虑适量增加资源,例如增加计算实例数量,或者提高计算实例的配置;而当工作负荷较低,则需要考虑是否减少计算实例,或者调低计算实例的配置。此外,例如在某些科学计算场景中,可以根据并行计算(Parallel Computing)任务数量的变化,对资源进行动态的伸缩性控制。 通常,在Windows Azure中,可以通过Management...

Azure实例数量及可用性保证
Nevin (Naiwen) Dong
Azure实例数量及可用性保证 偶然碰到这样一个情形,部署在Azure上的一个应用的webRole的instance找不到了。 虽然这种情形很少见,但需要了解一下这个现象,及对设计、开发和部署是否有其他要求,以确保app的可用性。 在目前的Windows Azure Platform的Portal里,创建一个新的部署的时候,系统会给出一个提示框,如下面的截图: 5734.20120822-small.tif 主要提示是: Warning: This deployment has at least one role with only one instance...
