Various embodiments of systems and methods for providing extended file storage for cloud applications are described herein. The method involves receiving a deployment request from a cloud application for file storage service, at the time of deployment. The deployment request includes information identifying a local folder and a mode of storage. The metadata relating to the information in the deployment request is stored in a persistent storage. Further, in response to receiving a start request to run the cloud application an application virtual machine is allocated and a block level storage volume is identified and attached to the application virtual machine. Further, the identified block level storage volume is mapped to the local folder identified in the stored metadata and the application virtual machine running the cloud application is started. The block level storage volume mapped to the local folder is accessed by application processes for performing read/write operations.

Providing extended file storage for applications

Example systems and methods of implementing an abstraction layer for a file repository are presented. In one example, an access request to retrieve an electronic file is received from a requesting device. The request includes an identification of a first storage location in the file repository. In response to the request, the first storage location of the file repository is searched for the electronic file. If the search is successful, the electronic file is retrieved from the file repository at the first storage location. If the search is unsuccessful, a redirection file is accessed in the file repository. The redirection file includes an identification of a second storage location for the electronic, file at a storage site external to the file repository. The electronic file is retrieved from the storage site based on the indication of the second storage location. The retrieved file is transmitted to the requesting device.

File repository abstraction layer

In an embodiment, a method is provided for accessing a file node. In this method, a file access request specifying a file node to be accessed by way of a file system is received at a server from a client device. A counter is referenced to identify that the file node is being accessed in response to a different file access request. The counter is configured to track whether the file node is being accessed. The file node is provided to the client device when the counter indicates a termination of access to the file node resulting from the different file access request.

File access using counter locking mechanism

Example systems and methods of managing installation of applications are described. In one implementation, a repository stores data associated with multiple application instances. An orchestrator analyzes application instances running on multiple provisioned virtual machines and identifies at least one unused virtual machine among the multiple provisioned virtual machines. The orchestrator terminates processes running on the unused virtual machine and clears data associated with the unused virtual machine. The cleared virtual machine is added to a virtual machine pool for use by another application instance.

Application installation management by selectively reuse or terminate virtual machines based on a process status

In an embodiment, a method is provided for accessing a resource. In this method, a HTTP request that defines an operation to be performed on an identified resource is received. The HTTP request is then parsed to extract an operation parameter from a header of the HTTP request. The HTTP request is executed based on the operation parameter to generate a result, and the result of the execution of the HTTP request is returned in an HTTP response.

Access of resources by way of hypertext transfer protocol

A method, apparatus, and system are provided for a Graphical User Interface (GUI) for monitoring classloading references. In an embodiment, the GUI includes a graphical representation of one or more resources of an application server. The one or more resources may be selectable via, for example, a cursor control device. In an embodiment, a graphical representation of a selected class loader and one or more associated classloading references are displayed in the GUI, responsive to receiving a selection input specifying one of the displayed resources.
