- Supports TCP (Layer 4) and HTTP/HTTPS (Layer 7) protocols
- Health checks can be TCP or HTTP based
- Fixed hostname format:
xxx.region.elb.amazonaws.com
How it Works
- The client connects to the CLB through a listener configured with a specific port and protocol
- The CLB routes incoming requests to registered EC2 instances (targets)
- Traffic is distributed based on the configured load balancing algorithm (e.g., round robin, least outstanding requests)
