In this episode you will learn:
- Application Load Balancers (ALB) operate at Layer 7 and are ideal for routing HTTP/HTTPS traffic based on content like URL paths.
- Network Load Balancers (NLB) operate at Layer 4, providing high performance and low latency for TCP/UDP traffic, along with a static IP address.
- Gateway Load Balancers (GWLB) operate at Layer 3 and are used to deploy and scale third-party virtual network appliances like firewalls.
- Health checks automatically detect unhealthy instances and reroute traffic to healthy ones to maintain application availability.
- The key differences in cross-zone load balancing: it is enabled by default for ALBs but disabled by default for NLBs.
