Systems and methods for managing applications
A method for maintaining applications may include: (1) receiving a request to recover a first application, (2) identifying a first production topology of the first application that identifies a set of resources upon which the application depends, (3) maintaining a template for transforming the first production topology of the first application into a first recovery topology for the first application, the template comprising information for mapping the first production topology to the first recovery topology, (4) applying the template to the first production topology at a first point in time to create the first recovery topology, and (5) recovering the first application to a first computing system using the first recovery topology. Various other methods, systems, and computer-readable media are also disclosed herein.

storing a set of changes that map the first production topology to the recovery topology.
11. The system of claim 9 , wherein the template-retention module is programmed to:
retrieve the template;
present at least a portion of information stored in the template to a user via a graphical user interface;
receive, via the graphical user interface, input that modifies at least one value stored in the template.
12. The system of claim 9 , wherein:
the first production topology and the recovery topology comprise markup-language documents;
the template comprises a markup-language transformation document.
13. A non-transitory computer-readable medium comprising one or more computer-executable instructions that, when executed by at least one processor of a computing device, cause the computing device to:
discover a set of resources upon which an application depends;
generate an application topology that identifies the set of resources;
for each resource in the set of resources:
identify a computer-executable command programmed to change a state of the resource;
include the computer-executable command in the application topology in a manner that associates the computer-executable command with the resource.
14. The non-transitory computer-readable medium of claim 13 , wherein the one or more computer-executable instructions are further programmed to cause the computing device to:
