Put the load balancer between users and change
Load balancers reduce single-instance risk and give you a cleaner place to manage public traffic, TLS termination, and backend distribution.What load balancers are for
- High-availability application entry points
- Routing traffic to healthy backends
- Keeping public exposure consistent during deployments
- Centralizing traffic behavior instead of configuring it per instance
Recommended setup flow
Decide the public entry pattern
Confirm which applications need internet-facing access and which can remain private behind internal layers.
Add listeners and health checks
Configure the ports, protocols, and health signals that match how the app actually behaves.
