20120110185 | Distributed Hierarchical Rendering and Provisioning of Cloud Services - Techniques are provided herein for distributed and hierarchical rendering and provisioning of cloud services. At a device in a cloud computing system comprising a plurality of hierarchical levels, a cloud service request is received for rendering and provisioning of a virtual data center. A determination is made as to which aspects of the cloud service request are to be satisfied by devices in a first hierarchical level and which aspects of the cloud service request are to be satisfied by devices in a second hierarchical level and in subsequent hierarchical levels. Rendering and provisioning commands are provided to one or more devices in the first hierarchical level that are selected to satisfy aspects of the cloud service request in the first hierarchical level. A subset cloud service request for aspects of the cloud service request that are to be satisfied by devices in the second hierarchical level is sent to a device in the second hierarchical level. | 05-03-2012 |
20120110186 | Disaster Recovery and Automatic Relocation of Cloud Services - Techniques are provided to move the services performed on one device to another device in a cloud computing system for a variety of reasons including failure, maintenance or upgrade of the device. A notification is received that services performed by an impacted device in a domain of a plurality of hierarchical domains need to be moved. A determination is made as to whether there are replacement resources available in the domain to perform the services, and if so, the replacement resources are automatically rendered to perform the services. The process continues to higher level domains that have a view into the capabilities of subordinate domains in order to determine where to move the services within the cloud computing system. | 05-03-2012 |
20120226789 | Hiearchical Advertisement of Data Center Capabilities and Resources - A cloud computing system is provided comprising a plurality of data centers, each data center comprising a plurality of pods each of which comprises network, compute, storage and service node devices. At a designated device of a data center, data center level capabilities summary data is generated that summarizes the capabilities of the data center. Messages advertising the data center level capabilities summary data is sent from a designated device of each data center to a designated device at a provider edge network level of the computing system. At the designated device at the provider edge network level, provider edge network level capabilities summary data is generated that summarizes capabilities of compute, storage and network devices for each data center as a whole and without exposing individual compute, storage and service node devices in each data center. | 09-06-2012 |
20120226790 | Extensible Attribute Summarization - In one embodiment a method includes at first a network device, identifying an attribute of the first network device, selecting a function that defines how the attribute is to be summarized together with a same attribute of a second network device, generating a message that comprises a set of information comprising an identification of the attribute and the function, and sending the message to, e.g., a next higher node in a network hierarchy of which the network device is a part. Multiple such messages may be received at an aggregation node that then summarizes the attributes according to respective functions, and sends or publishes a summarized version of the attributes to a still next higher node in the network hierarchy. | 09-06-2012 |
20120226799 | Capabilities Based Routing of Virtual Data Center Service Request - Systems and methods are provided for receiving at a provider edge routing device capabilities data representative of capabilities of computing devices disposed in a data center, the capabilities data having been published by an associated local data center edge device, and advertising, by the provider edge routing device, the capabilities data to other provider edge routing devices in communication with one another in a network of provider edge routing devices. The provider edge routing device also receives respective capabilities data from each of the other provider edge routing devices, wherein each of the other provider edge routing devices is associated with a respective local data center via a corresponding data center edge device, and stores all the capabilities data in a directory of capabilities. Thereafter, a request for computing services is received at the provider edge network and the methodology provides for selecting, based on the directory of capabilities, one of the data centers to fulfill the request for computing services to obtain a selected data center, and for routing the request for computing services to the selected data center. | 09-06-2012 |
20120233333 | Resource Negotiation for Cloud Services Using a Messaging and Presence Protocol - Techniques are provided for sending from a client in a first network device a first session-initiate message to a second network device that is configured to provide network layer, data link layer, or associated convergence layer based service connection information in order for the second network device to accept or reject a network layer, data link layer, or associated convergence layer based service connection with the first network device. The first session-initiate message is based on a messaging and presence protocol. A session-accept message is received at the client in the first network device that is configured to accept the service connection and provide a network layer, data link layer, or associated convergence layer based service connection information in order for the first network device to establish the service connection with the second network device. The session-accept message is based on the messaging and presence protocol. In response to receiving the session-accept message, the service connection is established. | 09-13-2012 |
20120239792 | PLACEMENT OF A CLOUD SERVICE USING NETWORK TOPOLOGY AND INFRASTRUCTURE PERFORMANCE - Techniques are described for selecting an optimal data center for instantiating a first cloud service. Embodiments of the invention receive a request specifying a topology of a first cloud service to be hosted by one of a plurality of data centers which provide computing resources to host a plurality of cloud services. A suitability value is then determined for each of the data centers which measures a fitness of the data center for instantiating the first cloud service. In one embodiment, the suitability value is determined by calculating a plurality of metric values for the data center, normalizing the metric values and calculating a weighted average of the normalized values. One of the data centers is then selected for instantiating the first cloud service, based at least in part on the determined suitability values. | 09-20-2012 |
20120303790 | Host Visibility as a Network Service - At a data switching device in a data center, it is detected whether a host has connected to a cloud computing network of which the data switching device and the data center are components. The detection is performed without directly communicating with the host. The data switching device determines properties of the host and generates a message comprising data representative of the properties of the host. The message is sent from the data switching device to a node in the cloud computing network that is configured to manage components of the cloud computing network associated with the host. | 11-29-2012 |
20120331147 | HIERARCHICAL DEFRAGMENTATION OF RESOURCES IN DATA CENTERS - Techniques are provided herein for defragmenting resources within a cloud computing system. The cloud computing system includes a plurality of servers deployed in a plurality of respective racks, wherein the respective racks are deployed in a pod of a data center. An element of the cloud computing system determines for each server in a given rack of servers a number of free resource slots available thereon and a number of resource slots in an idle state, and then further determines whether the number of free resource slots on a first server in the plurality of servers is greater than a predetermined threshold. When the number of free resource slots in the first server is greater than the predetermined threshold, a second server in the plurality of servers is identified with sufficient resource slots thereon to accommodate the number of resource slots in the idle state on the first server, and the resource slots in the idle state on the first server are caused to be migrated to the second server. | 12-27-2012 |
