Incorrect Load Balancer Configuration After Node Scaling

After node scaling, the load balancer failed to distribute traffic correctly due to misconfigured settings.

Find this helpful?

What Happened

Scaling added new nodes, but the load balancer configuration was not updated correctly, leading to traffic being routed to the wrong nodes.

Diagnosis Steps

1Checked the load balancer configuration and found that it was not dynamically updated after node scaling.
2Traffic logs showed that certain nodes were not receiving traffic despite having available resources.

Root Cause

Misconfigured load balancer settings after scaling.

Fix/Workaround

• Updated load balancer settings to ensure they dynamically adjust based on node changes.
• Implemented a health check system for nodes before routing traffic.

Lessons Learned

Load balancers must adapt dynamically to node scaling events.

How to Avoid

1Set up automation to update load balancer configurations during scaling events.
2Regularly test load balancer reconfigurations.
