Instances of an application pod may be deployed to many different computing environments spanning native cloud installations, SaaS providers, and on-premise data centers. In order to make uniform changes to a distribution of an application pod, a lock manager may receive and schedule lock requests from many different types of utilities. These utilities may schedule exclusive locks on the application pod throughout the different computing environments, such that patches, updates, security protocols, and other changes may be instituted without interference from changes made concurrently by other utilities. The lock manager may schedule immediate and future locks, with lock extensions and lock overrides available for flexibility.

Lock management for distributed application pods

In accordance with an embodiment, described herein are systems and methods for providing a compile-time dependency injection and lazy service activation framework including generation of source code reflecting the dependencies, and which enables an application developer using the system to build microservice applications or cloud-native services. The framework includes the use of a service registry that provides lazy service activation and meta-information associated with one or more services, in terms of interfaces or APIs describing the functionality of each service and their dependencies on other services. An application's use of particular services can be intercepted and accommodated during code generation at compile-time, avoiding the need to use reflection. Extensibility features allow application developers to provide their own templates for code generation, or provide alternative service implementations for use with the application, other than a reference implementation provided by the framework.

Systems and methods for compile-time dependency injection and lazy service activation framework

A system and method for providing a software modeling framework which supports different types of dependency injection and other software modeling or software development frameworks, and which allows software developers to develop models that strategically layer different components for different implementations. A service provider interface (SPI) enables different DI frameworks to be incorporated into the system; while an application provider interface (API) enable machines or implementations to be constructed. Extenders can be modeled so that, for example a particular bundle requires a handler for a particular configuration manifest entry; while a particular module provides handling of that manifest entry.

Software modeling framework

Embodiments of the invention provide systems and methods for implementing a logical programming model that separates a resource from its state and processes the resource and the state of the resource independently. According to one embodiment, a method of method for implementing a logical programming model can comprise defining a resource and defining one or more state objects for the resource. An application can be defined including at least one instance of the defined resource and at least one instance of the defined one or more state objects. Logic of the application can handle the one or more state objects independent from the resource.

Methods and systems for implementing a logical programming model

Embodiments of the invention provide systems and methods for implementing a virtual Storage Area Network (SAN) in software. According to one embodiment, a method for implementing a virtual SAN can comprise defining an application for accessing a computing grid for storing information wherein defining the application for accessing the computing grid for storing the information comprises defining a resource and defining one or more state objects for the resource, wherein the one or more state objects are handled independent from the resource. For example, the computing grid can comprise an Oracle Coherence grid. Such a computing grid can maintain a primary copy and a backup copy of the information and provides the backup of the information if the primary copy is unavailable. The information stored on the computing grid can be accessed via the application.
