    • A scalable cloud infrastructure serves two or more customers, where each customer is associated with at least one unit of virtual resources. The virtual resources are established by apportioning physical resources in the cloud infrastructure that are partitioned into pods within one or more zones in a scalable manner. Additionally, the cloud infrastructure establishes one or more management server clusters each comprising one or more management servers. The two or more customers create a number of virtual machines within pods in one or more zones. As customers interact primarily with the management server cluster to manage their virtual machine, a state and event handling method is devised to centralize the management of a potentially vast number of customer and supporting system virtual machines.
    • 可扩展的云基础设施为两个或更多客户提供服务,每个客户与至少一个虚拟资源单元相关联。 虚拟资源是通过在云基础设施中分配物理资源来建立的,这些资源以可扩展的方式分为一个或多个区域内的荚。 此外,云基础设施建立一个或多个管理服务器集群,每个管理服务器集群都包含一个或多个管 两个或多个客户在一个或多个区域内的pod内创建一些虚拟机。 随着客户主要与管理服务器集群进行交互以管理其虚拟机,设计了一种状态和事件处理方法来集中管理潜在的大量客户和支持系统虚拟机。

    • A scalable cloud infrastructure serves two or more customers, where each customer is associated with at least one unit of virtual resources. The virtual resources are established by apportioning physical resources in the cloud infrastructure that are partitioned into pods within one or more zones in a scalable manner. Each pod comprises a strongly connected discrete set of physical resources in a zone. Additionally, the cloud infrastructure establishes one or more management server clusters each comprising one or more management servers. Each management server is configured for allocating the units of virtual resources to an account associated with each customer. The traffic from two or more customer accounts within the scalable cloud infrastructure is isolated and segmented.

Additionally, the cloud infrastructure establishes one or more management server clusters each comprising one or more management servers. The two or more customers create a number of virtual machines within pods in a zone. Due to the scalability of the cloud infrastructure, customer virtual machines may exist in non optimal locations within the zone. A method to migrate virtual machines and defragment customer networks is devised to optimally manage network traffic and data communication in a scaled cloud infrastructure.

    • System for adjusting a power level of an optical signal at an input to a component in a network element that forms part of an optical network. The system includes a variable optical attenuator (VOA) for receiving a first optical input signal and producing an attenuated optical output signal. A detector is coupled to the input of the component for detecting a power value of a second optical input signal that is derived from the attenuated optical output signal. A VOA controller (VOAC) includes logic for receiving the power value, via a signaling channel, and generating selected control parameters that are input to a control input of the VOA for accordingly adjusting a VOA attenuation factor to achieve a selected signal power level at the input to the component.
