Application configurations, including applications themselves, application components, and modules associated with the application are installed on an application-server machine and stored in system-determined locations. These locations, or absolute paths, are then stored in a “loose configuration”. As new versions of applications, components, and/or modules are installed, they are placed in unique locations and given unique version numbers. A record of each application configuration version is stored and is referred to as “snapshots”. These snapshots provide a record of and pointers to the various elements that make up the various application configuration versions, so that at any time, a current version of an application configuration can be “rolled back” to a previous version of an application configuration. The methodology can be utilized to provide a self-healing configuration, whereby a faulty version of an application configuration can be rolled back to a previous version automatically.
