Abstract: A multi-layer architecture is provided for elastic provisioning of virtualized computing resources. The multi-layer architecture comprises a physical hardware layer comprising a plurality of physical computing machines, a distributed operating system layer that aggregates and virtualizes the computing resources, and a virtual machine layer that comprises virtual machines provisioned, by the distributed operating system layer, with virtualized computing resources. Elastic provisioning of virtualized computing resources comprising receiving computing resource information of a plurality of physical computing machines, producing virtualized computing resources by aggregating the received computing resource information of the plurality of physical computing machines, and provisioning the virtualized computing resources among a plurality of virtual machines.

Abstract: Methods and systems for monitoring and controlling a service level agreement are disclosed. A disclosed embodiment comprises a cloud platform hosting at least one application associated with at least one service level agreement, a monitoring module for collecting at least one metric relating to an application hosted on the cloud platform and terms of a service level agreement associated with each of the one or more metrics, and monitoring the metric collected against a service level objective in the service level agreement. The system may additionally comprise a controlling module for mapping a service level objective to a predefined operation rule, identifying one or more actions to be taken in accordance with the rule, assigning a priority to the one or more actions identified in accordance with the rule; and performing the one or more actions in accordance with the assigned priority of each of the one or more actions.

Abstract: Systems and methods for deriving a service level agreement for an application hosted on a cloud platform are defined. In accordance with at least one embodiment, deriving the service level agreement comprises packaging the application for deployment on a cloud platform, executing the packaged application in a sandboxed environment and capturing one or more application performance characteristics thereby, executing the packaged application in a sandboxed virtualized platform and further capturing one or more application performance characteristics thereby, mapping the one or more captured application performance characteristics to one or more service level objectives, and deriving a service level agreement on the basis of the one or more service level objectives, wherein the service level agreement comprises at least one of the one or more service level objectives.

Abstract: Composite applications can be created that utilize a plurality of different services across a plurality of different cloud stack layers. The composite applications are defined using the Service Component Architecture (SCA) model. Composite applications can be translated from the SCA model into a format compatible for a virtualization platform, such as the Open Virtualization Format (OVF). Composite applications, as defined in the format compatible for the virtualization platform, can be deployed on the virtualization platform.
