Embodiments for policy-driven high availability (HA) standby servers in a multi-server high availability (HA) computing environment. Policies may be created that define selected sessions for a user (e.g., important sessions to the user) such that only one or more artifacts of each selected session are replicated to one or more HA standby servers. The one or more artifacts and the one or more policies of a selected session may be synchronized from a primary server to the one or more HA standby servers.

Policy-driven high availability standby servers

A computer-implemented method, according to one embodiment, includes: sending a request to a target server to initiate a unidirectional connection, receiving a reply indicating whether the target server is capable of hosting the unidirectional connection or indicating identification of a unidirectional port, initiating a unidirectional connection to the identified unidirectional port of the target server in response to the reply providing the identification of the unidirectional port, sending a request to begin sending data to the target server over the unidirectional connection, receiving a response from the target server indicating that the target server is ready to receive data over the unidirectional connection, sending data to the target server over the unidirectional connection, sending a termination message over the unidirectional connection in response to sending the data to the target server, terminating the unidirectional connection, and performing a next communication with the target server over the TCP/IP connection.

Data transfer policies between source and target servers in a wide area network

A computer-implemented method, according to one embodiment, includes: transferring data over a network using a first mode, at least one of randomly, periodically and continuously determining network performance characteristics during the transferring, applying a policy to the network performance characteristics determined during the transferring, continuing to use the first mode of data transfer in response to a result of applying the policy mandating continued use of the first mode, selecting a second mode of data transfer in response to the result of applying the policy mandating use of the second mode, and transferring data over the network using the second mode in response to selecting the second mode.
