Abstract: The present invention extends to methods, systems, and computer program products for implementing a tenant provisioning system in a multi-tenancy architecture using a single provisioning master in the architecture, and a data center provisioner in each data center in the architecture. The provisioning master receives user requests to provision a tenant of a service and routes such requests to an appropriate data center provisioner. Each service in the multi-tenancy architecture implements a common interface by which the corresponding data center provisioner can obtain a common indication of load from each different service deployed in the data center thus facilitating the selection of a scale unit on which a tenant is provisioned. The common interface also enables a service to dynamically register (i.e. without redeploying the tenant provisioning system) with the provisioning master as a multi-tenancy service by registering an endpoint address with the provisioning master.

Abstract: The present invention extends to methods, systems, and computer program products for processing model based commands for distributed applications. Embodiments facilitate execution of model-based commands, including software lifecycle commands, using model-based workflow instances. Data related to command execution is stored in a shared repository such that command processors can understand their status in relationship to workflow instances. Further, since the repository is shared, command execution can be distributed and balanced across a plurality of different executive services. Embodiments also include model-based error handling and error recovery mechanisms.

Abstract: Embodiments of the present invention provide the ability to effectively visualize the mapping between two schemas, referred to herein as a source schema (or first schema) and a destination schema (or second schema), regardless of the size or complexity of the schemas and mappings. According to one aspect of the present invention a method for visually representing a mapping between a first schema and a second schema is provided. The method includes receiving a selection of an object, emphasizing the selected object and identifying a plurality of objects that are relevant to the selected object. The objects that are identified as being relevant to the selected object are also emphasized.

Abstract: The present invention extends to methods, systems, and computer program products for managing software lifecycle. Based on declarative models and knowledge of their interpretation, embodiments of the present invention facilitate lifecycle management for model-based software applications. Lifecycle models, such as, for example, lifecycle state machine models are stored in a shared repository such that executive services can determine how software application lifecycles are to be managed and transitioned. Software lifecycle activities can verify that a transition is possible and identify any errors preventing a lifecycle transition. Model-based error handling and error recovery mechanisms can be used to correct any identified errors.

Abstract: A distributed application deployment engine uses declarative deployment data that describes deployment characteristics for application modules, and potential target environments. The engine uses the deployment data to potentially match a module to a deployment target. At some point, the modules may then be actually deployed on the identified deployment target. This may be performed for multiple modules in the distributed application, thereby deploying the distributed application in a distributed environment.

Abstract: An interactive user interface for displaying mappings between modules of a distributed application and deployment targets in a distributed environment. The user interface represents module items, deployment target items, and correlation items that represent various mappings of module items to deployment target items. In some cases, the manner in which each of these items is displayed may be altered in response to user input. The correlation itself may also be potentially altered in response to user input. Multiple solutions may be displayed in which there are different mappings of modules to target solutions.

Abstract: The present invention extends to methods, systems, and computer program products for distributed behavior controlled execution of modeled applications. Embodiments of the invention facilitate the interoperation of a central data store along with various peer-to-peer functionalities. Thus, distributed applications can be executed in an environment that utilizes advantages of both a central data store and peer-to-peer messaging. A read-only portion of a centralized data store can be used to provide some behavior control over various processing systems during execution of a distributed software application. Thus, embodiments of the invention can be used to form a policy-driven collective of nodes forming a distributed, decentralized run-time for model-based applications. Utilizing a cooperating collective of nodes that comply with centralized polices and execute applications over a peer-to-peer fabric permits a distributed application runtime to accommodate distribution and decentralization on a large scale.

Abstract: Various technologies and techniques are disclosed that merge components on a design surface. The system receives input from a user to add components or clauses to a design surface and analyzes the components to determine if some of the components can be merged. If the system identifies components that can be merged, then the system merges the identified components to reduce the number of components present on the design surface. The system determines that some components can be merged if the components meet the same criteria, such as having components that are equivalent and that have the same number of incoming paths or the same number of outgoing paths. The system provides a visual indicator on the design surface to indicate that components are being merged. The system provides an undo feature to allow the user to undo the component merging when desired.

Abstract: The present invention extends to methods, systems, and computer program products for performing requested commands for model-based applications. Embodiments of the invention permit efficient implementation of operations for model-based applications. Since drivers that are to implement an operation request data for implementing the operation, embodiments significantly reduce the likelihood of superfluous data being exchanged between an executive service and drivers. Further, if an operation is interrupted before implementation is complete, the operation can be resumed without having to re-perform already completed portions of the operation. Additionally, a user can be regularly updated on the progress of their commands.

Abstract: Abstracting communication with a plurality of containers. Each container encapsulates or hosts a module (e.g., a web service, a database, etc.) associated with a distributed application. A meta-container communicates with drivers that interface with each of the containers. The meta-container represents an abstraction and a virtualization of the containers in the hierarchy. Each container may also be a meta-container for other containers. The recursion and layered hierarchy provide flexible, extensible, and efficient management of the distributed application.
