1. A method comprising:

determining, by a processor communicatively connected to a memory, a first failure group of a first instance of an application;

establishing a connection between the first instance and a second instance associated with a peer application;

determining a second failure group of the second instance;

comparing the first failure group to the second failure group; and

periodically requesting failure group information of at least one of the first instance, the second instance, and the third instance;

receiving new failure group information of an updated instance;

determining a new failure group for the updated instance; and

comparing the new failure group to the first failure group.

17. The tangible non-transitory machine-readable storage medium of claim 13 , wherein the instructions for determining the first failure group of the first instance comprise instructions for determining the first failure group based on a physical address of the processor.

18. A cloud network comprising:

a data center having a plurality of computing resources including a plurality of processors;

a cloud manager configured to:

manage a plurality of application instances by assigning computing resources including at least one processor to each application instance;

provide a universally unique identifier to an application instance identifying the at least one processor assigned to the application instance;

provide a listing of network addresses of a plurality of peer application instances providing a service,

wherein at least one of the application instances is configured to:

determine a first universally unique identifier of a processor assigned to the application instance and a second universally unique identifier of a processor assigned to a peer application instance;
