= IBM Multi-site Workload Lifeline = Multi-site Workload Lifeline (Lifeline) is an IBM workload monitoring and routing solution designed to intelligently load balance workloads across two centers (or sysplexes). Lifeline supports the following workload types:
 * TCP/IP based workloads
 * Linux on z Systems workloads
 * SNA workloads
 * MQ cluster workloads
 * Db2 sysplex routed workloads

Lifeline is also one of the products required for the GDPS Continuous Availability (previously called GDPS/Active-Active) solution. This solution aims to significantly reduce the time spent to recover systems in a disaster recovery situation. Lifeline is used to switch workloads between sites in the event of a planned or unplanned outage.

Components
Lifeline consists of two key components: The Lifeline Agent(s) and Lifeline Advisor.
 * Lifeline Agent(s): A monitoring program that collects health information about a site (or sysplex), along with the health of the specified applications in a workload
 * Lifeline Advisor: A coordinating program that collects the health reports by the agents, and provides load balancing recommendations to an external load balancer (such as F5)
