Load Balancing
Distribute incoming traffic across multiple application servers to prevent bottlenecks and downtime.
What this is
A managed load balancing layer that sits in front of your application instances, continuously health-checking backend nodes and routing traffic evenly to maintain rapid response times.
How it works
- 1Incoming web requests arrive at redundant load balancer IP endpoints.
- 2Active health checks monitor application response codes on each backend server.
- 3Unhealthy nodes are automatically removed from the rotation without dropping connections.
- 4SSL termination and HTTP/2 negotiation handled centrally at the load balancer.
What's included
| Protocols | HTTP, HTTPS, TCP, UDP |
| Algorithms | Round-robin, least connections, source IP hashing |
| Health Checks | Custom HTTP status code and TCP port probes |
| SSL Offloading | Centralized certificate management and TLS offloading |
Suitability assessment
✓ When this makes sense
- •High-traffic websites where a single server cannot handle peak concurrency.
- •Zero-downtime rolling deployments where servers are updated one at a time.
- •Mission-critical applications requiring active-active redundancy.
✕ When it doesn't
- •Small utility scripts or early-stage applications running comfortably on one instance.

Frequently asked questions
Yes. SSL certificates can be terminated at the load balancer, offloading encryption overhead from backend application servers.
