Following are few use cases where this pattern will be a right fit:

• Near real-time systems: Latency optimized load balancing is best suited for environments which are very dynamic in terms of the load they encounter and require high performance in terms of turnaround time for requests.
• Geo-dispersed deployments: This pattern is highly recommended for Geo-dispersed deployments of Microservices which caters to consumers around the world. Optimizing the routing logic helps improve the turnaround time for responses thereby providing a better performance.
• Highly available systems: Apart from optimizing the route, latency optimized load balancer can also be used to enable an automatic failover strategy. The service will start routing the request to a different Geo-location if it sees the performance degrading in the preferred location.
