1. A system comprising:
a processor; and
a machine-readable storage medium comprising instructions executable by the processor to:
monitor status of a first application server instance executing within a cluster computing environment, wherein the first application server instance is to implement a communication session established using a signaling protocol;
on determining that the first application server instance is non-operational, select a second application server instance; and
cause a mid-session request, received from a communication network, to be directed to the second application server instance, wherein the mid-session request pertains to the communication session; and
cause the second application server instance to process the mid-session request based on one of a communication state information and an application state information corresponding to the communication session implemented by the first application server instance, wherein the communication session is continued to be supported by the second application server instance.
