A cloud system may create and support multiple network offerings for virtual machines in a cloud zone. Physical networks comprising sets of network elements, such as routers, gateways, firewalls, load balancers, and other network hardware, may be created and updated within a zone. Network offerings may be defined and associated, using tags or other techniques, with virtual machine networks, physical networks and/or network elements. Cloud end users may request specific network offerings when creating virtual machines, or may request to move existing virtual machines from one network offering to another. The cloud system may use the requested network offering to identify the virtual machine network, physical network, and/or network elements corresponding to the requested network offering. The cloud system may allocate a new virtual machine network and configure the network elements within the associated physical network to provide network services to the virtual machine.

Network offering in cloud computing environment

A diagnostic virtual machine having access to resources of an infrastructure as a service cloud may be created. A user device may be provided access to the diagnostic virtual machine. In some embodiments, the diagnostic virtual machine may be configured to monitor a cluster of hypervisors, and the resources of the infrastructure as a service cloud which the diagnostic virtual machine has access to may include physical resources of the infrastructure as a service cloud that are associated with the cluster of hypervisors.

Creating multiple diagnostic virtual machines to monitor allocated resources of a cluster of hypervisors

Methods and systems for managing cloud zones are described herein. A management server for a cloud of computing resources may add private zones to the cloud. The private zones may contain computers owned and operated by a user of the cloud, such as a cloud customer, rather than the cloud operator. The management server may manage the computing resources in the private zone by sending commands to an agent, which in turn relays the management server's commands to the individual computing resources. The agent may be authenticated using a token.

Managing cloud zones

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 a zone. Due to the scalability of the cloud infrastructure, a console proxy virtual machine and server is introduced to support console access to virtual machines. The console proxy server serves as an intermediary between a browser and a viewed virtual machine configured to maintain viewing session quality while minimizing network impact.

Methods and systems for management of cloud computing resources are described herein. A management server for a cloud of physical computing resources may assign states to individual physical computing resources or groups of physical computing resources. The states may include a disabled state, in which only administrator access to the resources is permitted; an enabled state, in which user access to the resources is permitted; a restricted state, in which some, but not all user requests to the resources are permitted; and an unmanaged state, in which no communications between the resources and the management server are permitted.

Assigning states to cloud resources

A cloud system may create physical resource tags to store relationships between cloud computing offerings, such as computing service offerings, storage offerings, and network offerings, and the specific physical resources in the cloud computing environment. Cloud computing offerings may be presented to cloud customers, the offerings corresponding to various combinations of computing services, storage, networking, and other hardware or software resources. After a customer selects one or more cloud computing offerings, a cloud resource manager or other component within the cloud infrastructure may retrieve a set of tags and determine a set of physical hardware resources associated with the selected offerings. The physical hardware resources associated with the selected offerings may be subsequently used to provision and create the new virtual machine and its operating environment.

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 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.

Network fragmentation and virtual machine migration in a scalable cloud computing environment

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.

Event and state management in a scalable cloud computing environment

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.
