Embodiments of the present invention disclose a method, computer program product, and system for memory replication. In one embodiment, in accordance with the present invention, the computer implemented method includes the steps of executing a mobile agent on a server node, wherein the server node is within a cluster of server nodes connected via network communications, capturing a memory state of the server node during operation of the server node, wherein the memory state includes session information stored on computer memory of the server node, which is captured and stored by the mobile agent, monitoring the server node to determine whether the server node has failed, and responsive to determining that the server node has failed, migrating the mobile agent to an active server node within the cluster of server nodes, wherein the mobile agent carries the captured memory state.
