Study Notes
Cross-Zone Load Balancing Overview
- Cross-zone load balancing allows load balancer nodes to distribute traffic across all registered targets in enabled Availability Zones.
- When disabled, traffic distribution is limited to targets in the same Availability Zone as the load balancer node.
Application Load Balancers
- Cross-zone load balancing is always enabled for Application Load Balancers, ensuring even traffic distribution.
Network and Gateway Load Balancers
- For Network Load Balancers and Gateway Load Balancers, cross-zone load balancing is disabled by default, requiring manual activation for broader traffic distribution.
Traffic Distribution When Disabled
- In a scenario with cross-zone load balancing disabled:
- Each of the three targets in Availability Zone A receives 16.6% of total traffic.
- Each of the two targets in Availability Zone B receives 25% of total traffic, leading to imbalanced traffic if zones have unequal targets.
Traffic Distribution When Enabled
- When cross-zone load balancing is enabled, traffic is distributed more evenly across all available targets in all enabled Availability Zones, improving overall resource utilization.
