20090248693 | MANAGING DATA TRANSFER BETWEEN ENDPOINTS IN A DISTRIBUTED COMPUTING ENVIRONMENT - A file fetcher manager provides commonly-utilized management and resource allocation for multiple file fetchers that each implement a different type of mechanism or protocol for transferring data files between peer endpoints in meshes associated with a cloud-computing service. Each file fetcher is configured with both client-side and server-side components to retrieve and serve out data files. The file fetcher manager encapsulates the file fetchers to provide an abstract interface to callers while hiding the underlying details of the file fetchers. The file fetcher manager is arranged for managing simultaneous operations of the multiple file fetchers to route requests from the callers to the appropriate file fetchers, and for scheduling work items for the file fetchers so that data transfers efficiently utilize available resources while keeping the entire transfer process coherent and organized. | 10-01-2009 |
20090300169 | SYNCHRONIZATION THROTTLING BASED ON USER ACTIVITY - Synchronization of data across multiple endpoints in a mesh network that supports a data sharing service is throttled responsively to user activity in the network by monitoring the activity using a component in a mesh operating environment (“MOE”) runtime that is instantiated on each endpoint. The monitoring may include the collection of data that can be used to infer user activity, as well as data that explicitly indicates activity. State information is maintained so that data can be synchronized across the endpoints even when a user goes offline from the service. When the user logs on to the service, makes changes to a shared file, or the endpoint device starts up upon connection to a mesh network, throttling is performed by prioritizing work items associated with synchronization operations so that resources on the endpoint are not excessively consumed which could reduce the quality of the user experience. | 12-03-2009 |
20110307442 | TRANSPARENT ACCESS MECHANISM FOR LOCAL AND REMOTE DATA - A unified data access mechanism can provide transparent access to data that is either stored locally or remotely. Application programs can direct data requests and data modifications to this singular component without foreknowledge of where the data is stored. The unified data access mechanism can work in concert with a synchronization mechanism that can maintain data synchronization between local data and remote data. Requested or modified data can be identified as stored locally or remotely based on the namespace of the data. If the data is stored remotely, the user credentials associated with the user's process space within which the application program is executing can be utilized to identify, and then provide, relevant authentication information to the remote data store, should it be required. | 12-15-2011 |
20120159424 | DISTRIBUTED APPLICATION MANIFEST - A method of creating a manifest for a distributed application is disclosed. Components and composites of components of the distributed application are described in a technology agnostic manner. The description includes a definition of the scalability of the composites of components. | 06-21-2012 |
20120159425 | APPLICATION MODEL FOR IMPLEMENTING COMPOSITE APPLICATIONS - Embodiments are directed to providing an application model for implementing composite applications and to providing a declarative programming model and distributed runtime for creating and executing composite applications. In an embodiment, a computer system instantiates an application model. The application model allows users to compose composite applications. The composite applications are configured to run on both distributed computing systems and local computing systems. The computer system receives user input at the instantiated application model. The user input indicates which composite application components are to be used in conjunction with each other to form the composite application. The computer system also provides the composite application on a distributed computing system and/or a local computing system. | 06-21-2012 |
20120222003 | DISTRIBUTED APPLICATION DEFINITION - A method of creating an application definition for a distributed application is disclosed. Constructs corresponding with a schema of the distributed application are defined in a declarative and technology agnostic manner. The constructs include the application definition, a module definition, and a component definition. Each construct includes metadata. | 08-30-2012 |
20120246613 | DISTRIBUTED COMPONENT MODEL - A distributed component model for creating a scalable and available distributed application is disclosed. The distributed component model provides for an application schema to be declaratively defined to include a module having a component. The schema includes a corresponding definition construct in a technology agnostic manner. The corresponding definition construct is declaratively defined to include metadata to control scaling and availability. | 09-27-2012 |
20120254109 | DISTRIBUTED COMPONENT RUNTIME - A method of creating a distributed application in a distributed component runtime is disclosed. An application schema including distributed modules is declaratively defined. Each module hosts a component having a corresponding logical address. Mapping the corresponding logical addresses to physical addresses at runtime virtualizes interactions between the components. | 10-04-2012 |
20120260227 | STATEFUL COMPONENT AUTHORING AND EXECUTION - A method for of authoring and executing stateful components for a distributed application is disclosed. An application schema for the distributed application is declaratively defined and includes a plurality of distributed modules. Each module hosts a set of stateful components co-located in a physical tier of a distributed environment having logic to manipulate state. The runtime supports partitioning the stateful components. Control flow opaqueness of component logic is banished in each of the stateful components, which would otherwise occur if state was externalized. | 10-11-2012 |
