Techniques are disclosed for patching applications having software components with vulnerabilities. Upon receipt of a notification that a version of a software component has a vulnerability, a database of metadata is accessed to identify software applications which include the version of the software component. The identified software applications are cloned, and the version of the software component is replaced with a newer version which is free from the vulnerability to patch the application. The patched software application is then tested on a cloud computing test environment, and upon a successful test, deployed to a cloud computing production environment.

Systems and methods for patching vulnerabilities

Systems and methods for managing multiple versions of applications executing on servers in a server pool are provided. A request to generate new session data for a transaction requested by a user is received by a first server executing a first version of an application. A determination is made that the first version of the application is unsuitable to process the request. An identity of a second server executing a second version of the application is requested by the first server in a server pool comprising one or more servers, and an appropriate second server is selected. The first server transmits a hypertext transfer protocol proxy request to the selected second server, which generates the new session data.

Session management in a mixed mode environment

Systems and methods for managing multiple versions of applications executing on servers in a server pool are provided. A first server executing a first version of an application loads session data associated with a second, different version of the application. An error is detected based on the difference between the first version and the second version. A second server executing the second version of the application is selected by the first server in a server pool comprising one or more servers. The first server transmits a hypertext transfer protocol proxy request to the selected second server, which successfully processes the session data and handles the request without error.
