Technologies are described herein for differentiating normal operation of an application program from error conditions to predict, diagnose, and recover from application failures. Access to resources by the application program is monitored, and resource access events are logged. Resource access patterns are established from the logged resource access events utilizing computer pattern recognition techniques. If subsequent access to resources by the application program deviates from the established patterns, then a user and/or administrator of the application program is notified of a potential error condition based on the detected deviation. In addition, sequences of resource access events that deviate from the established resources access patterns are correlated with an error condition based on a temporal proximity to the time of occurrence of the error to provide diagnostic information regarding the error.

Predicting, diagnosing, and recovering from application failures based on resource access patterns

The dependencies of an application are identified by intercepting application programming interface calls made by an application. A determination is then made at the runtime of the application as to whether the dependencies of the application are present. If the dependencies are not present, a client device upon which the application is executing is configured such that the dependencies are present and are made available only to the authorized application. If the dependencies are present and the application is authorized to interact with the dependencies, the application is permitted to execute.

Satisfying application dependencies

Configuration items for a software application can be automatically and/or manually discovered, and the application can be packaged to form a virtual application package. A deployment configuration can include settings for the configuration items. The deployment configuration can be set after packaging the software application. For example, a selected configuration item in the deployment configuration may be changed in response to user input. The virtual application package can be deployed to instantiate the application one or more times, and the deployment configuration can be applied in the instantiated application.

Virtual software application deployment configurations

Determining a discrete application boundary. A method includes identifying one or more initial components of an application. The method further includes identifying statically and/or dynamically related components of the one or more initial components of the application. Identifying statically related components and identifying dynamically related components is performed iteratively. The method further includes identifying a discrete boundary for the application based on statically related components and dynamically related components.

Identifying application resources through implicit application models

An extensible virtualization system provides an object model and manages a virtual application lifecycle in a way that allows new virtualization subsystems to be added to extend a virtualization product without reworking the product itself. Virtualizing an application generally involves three steps: metadata extraction, metadata storage and reconstitution, and runtime management of requests. The extensible virtualization system receives notification of an application preparation session and allows virtualization subsystems to monitor the session to collect configuration information specific to each subsystem that the application uses to run on a client. Each subsystem provides collected information to the extensible virtualization system, which stores the collected information until the application to be virtualized is deployed. When the application is deployed, the system invokes the same virtualization subsystem and provides the subsystem with the stored information.

Extensible application virtualization subsystems

An application virtualization system enables server applications, such as web applications to be easily deployable, separates an application and its state from the system, and allows applications to be easily moved to another server. The application virtualization system provides a way to isolate conflicts and allow multiple applications that provide conflicting information to run independently and avoid conflicts. The application virtualization system receives notification of an application preparation session and monitors the session to collect configuration information that the application uses to run on a client. The application virtualization system stores the collected information until the application to be virtualized is deployed. When an administrator later deploys the application, the system retrieves the stored information and uses the information and information from the client to reconstitute the metadata and virtualize the application.
