Elastic Load Balancing
Use this page as a service-specific case-study starter for architecture, simulation, and optimization scenarios in pinpole.cloud.
Why this service matters
ELB distributes traffic across targets (EC2, containers, IPs, Lambda).
Power:
- ALB (L7): content-based routing, host/path-based rules, native HTTP/2 & WebSocket
- NLB (L4): ultra-low latency, static IP/Elastic IP, millions of requests per second
- GLB (L3): third-party virtual appliances (firewalls, IDS, deep packet inspection)
- Cross-zone load balancing for even traffic distribution
- Sticky sessions for stateful applications
Important workflows
- Register Target - Register a new target (instance, IP, or Lambda) with a target group
- Create Listener - Add a new listener rule to the load balancer
- View Health - Check the health status of registered targets
