Example implementations relate to passing a cookie between client devices such that, based on the cookie, connections to the application from the client devices are mapped to a given application instance. A request may be transmitted to an application instance connector to connect to an application. The application may be implemented by multiple application instances. A cookie associated with a given application instance of the multiple application instances may be received from the application instance connector. The cookie may cause connections to the application from client devices having the cookie to map to the given application instance. The cookie may be passed from a first client device to a second client device such that, based on the cookie, connections to the application from the second client device are routed to the given application instance.

Connecting application instances to client devices

Embodiments of the present invention provide methods and systems for leadership allocation in a distributed computer system. In certain embodiments of the present invention, a leader-election-service process runs within each node of a distributed computer system, together cooperatively providing a distributed-leader-election service. The distributed-leader-election service employs a distributed consensus service to manage distributed state information related to roles and leadership allocation within a distributed computer system. Client processes within each node interface with the leader-election-service process of the node in order to assume leadership of particular roles within the distributed computer system. Leadership-allocation management is thus centralized, within each node. In alternative embodiments, the distributed-leader-election service may be implemented as a collection of library routines that run in the context of client processes.
