Load Balancing: Round Robin vs. Smart Routing vs. Service Mesh
This decision page will help you decide which approach to load balancing and traffic routing to use for your application or system.
Answer a few questions → Get a clear recommendation.
Options you can choose from:
Round Robin
Sends each new request to the next server in turn, spreading the load evenly. Best for simple setups where all servers are equal and each request is independent.
Smart Routing
Sends requests to the server that is best suited at that moment based on how busy each server is or whether it is healthy, making it better suited for systems where servers may differ in capacity.
Service Mesh
Adds a small helper process alongside each service that automatically handles routing, security, retries, and monitoring. It is powerful but complex and requires a container management system like Kubernetes.
