20080270411 | DISTRIBUTED BEHAVIOR CONTROLLED EXECUTION OF MODELED APPLICATIONS - 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. | 10-30-2008 |
20080270585 | META-CONTAINER FOR MODEL-BASED DISTRIBUTED APPLICATIONS - 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. | 10-30-2008 |
20090006062 | PROGRESSIVELY IMPLEMENTING DECLARATIVE MODELS IN DISTRIBUTED SYSTEMS - A system for automatically implementing high-level instructions in a distributed application program, where the high-level instructions reflect the behavior of the distributed application program, includes at least a tools component. The tools component is used to write high-level instructions in the form of declarative models, and place them in a repository. An executive component then receives the declarative models from the repository and refines them (e.g., via progressive elaboration) until there are no ambiguities. A platform-specific driver then translates the commands from the executive component, effectively turning the declarative model instructions into a set of imperative actions to be implemented in one or more application containers. The platform-specific driver also relays one or more event streams to an analytics means, which can result in modifications to the declarative models and corresponding new sets of instructions coming through the platform-specific driver at a later point. | 01-01-2009 |
20090006063 | TUNING AND OPTIMIZING DISTRIBUTED SYSTEMS WITH DECLARATIVE MODELS - A system for automatically adjusting operation of a distributed application program includes analytics means having a monitoring component. The monitoring component receives one or more event streams of data corresponding to execution of one or more modules of the distributed application program. The monitoring component joins the received event streams with one or more declarative models to create operational data. A forensics component of the analytics means queries, such as by using data from a declarative model store, the operational data to identify trends or behavior information for the various modules or components of the distributed application program. A planner component then reviews data created by the forensics component to identify any needed changes to the declarative models. The planner component passes any modified declarative models back to the system, so that the distributed application program can operate more efficiently using the changes to the declarative models, as needed. | 01-01-2009 |
20090055838 | MONITORING DISTRIBUTED APPLICATIONS - The present invention extends to methods, systems, and computer program products for monitoring distributed applications. Declarative application models are used. Operational data for a deployed application can be compared to an application intent expressed in a corresponding declarative application to provide more effective monitoring of application behavior. Application components can subscribe to an event fabric to receive configurations that indicate what events the application is to emit (i.e., publish into the event fabric) for monitoring. Thus, applications essentially subscribe to produce information (as opposed to subscribing to receive information). Monitoring can be dynamically adjusted in response to environment changes. | 02-26-2009 |
20090112559 | MODEL-DRIVEN, REPOSITORY-BASED APPLICATION MONITORING SYSTEM - Enabling and processing events. To enable events, an application model correlated to an application is declaratively defined. The application model describes operations of the application. One or more event models correlated to the application model are declaratively defined. The event models describe application execution locations where events are desired to be emitted in the execution of the application. Based on the correlation of the event models to the application models, the applications are instrumented with instrumentation code to cause the application to emit events at the execution locations. To process events an application model is defined. The application model includes one or more observation models. The observation models include a correlation of events to the observation model by defining instrumentation models in the application model. An event is received. The event is applied to the observation model based on the correlation. The event is processed according to the observation model. | 04-30-2009 |
20090112873 | PROCESSING MODEL-BASED COMMANDS FOR DISTRIBUTED APPLICATIONS - 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. | 04-30-2009 |
20090113379 | MODELING AND MANAGING HETEROGENEOUS APPLICATIONS - The present invention extends to methods, systems, and computer program products for modeling and managing heterogeneous applications. Application intent can be described in a relatively straight forward manner that abstracts underlying implementation details. Thus, application developers can develop applications without necessarily having to know extensive details of an underlying implementation environment. In any event, an application can be executed in different implementation environments without requiring changes to the corresponding model. | 04-30-2009 |
20090113407 | MANAGING SOFTWARE LIFECYCLE - 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. | 04-30-2009 |
20090113437 | TRANSLATING DECLARATIVE MODELS - The present invention extends to methods, systems, and computer program products for translating declarative models. Embodiments of the present invention facilitate processing declarative models to perform various operations on applications, such as, for example, application deployment, application updates, application control such as start and stop, application monitoring by instrumenting the applications to emit events, and so on. Declarative models of applications are processed and realized onto a target environment, after which they can be executed, controlled, and monitored. | 04-30-2009 |
20090113457 | PERFORMING REQUESTED COMMANDS FOR MODEL-BASED APPLICATIONS - 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. | 04-30-2009 |
20090313620 | SYNCHRONIZING VIRTUAL MACHINE AND APPLICATION LIFE CYCLES - A virtual environment can be configured to coordinate life cycles of virtual machines and application programs executing therein. In one implementation, the virtual environment includes an application layer and a virtual machine layer. The application layer communicates with the virtual machine layer to coordinate and directs virtual machine creation and deletion in a coordinated fashion with application programs. For example, the application layer receives a request to initiate an application program. The application layer determines from associated application properties the type and/or number of virtual machines to be created. The application layer then directs creation of the appropriate virtual machines (through the virtual machine layer), and further directs installation of the requested application programs therein. When detecting removal of the application program from the created virtual machines, the application layer can automatically direct removal or decommissioning of the corresponding virtual machine. | 12-17-2009 |
20100299678 | DYNAMIC EVENT COLLECTION AND STRUCTURED STORAGE - In one embodiment, a computer system accesses an event associated with an activity, where the activity has been executed by a runtime as part of a software application. The runtime includes a software hook configured to listen for event stream operation indications from the user. The computer system tags the accessed event with an additional portion of identification information that uniquely identifies the executed activity. The computer system receives an event stream operation indication from the user indicating that event transmission for an identified event stream is to be dynamically enabled or disabled and identifies the user-indicated event stream using the tagged identification information. The computer system also dynamically performs the indicated event stream operation on the identified event stream according to the user's indication. | 11-25-2010 |

20110179303 | PERSISTENT APPLICATION ACTIVATION AND TIMER NOTIFICATIONS - The present invention extends to methods, systems, and computer program products for persistent application activation and timer notifications. A durable instance manager, instance execution hosts, and an instance store interoperate to transition instances between executing and persisted states. System properties are associated with an instance. System properties can define re-activation conditions, that when satisfied, indicate that an instance is to be re-activated for execution. System properties can define timers as well as indications that instances are in a persisted but ready to run state. | 07-21-2011 |
