Autoscaling Slow Due to Cloud Provider API Delay

Pod scaling was delayed due to cloud provider API delays during scaling events.

Find this helpful?

What Happened

Scaling actions were delayed because the cloud provider API took longer than expected to provision new resources, affecting pod scheduling.

Diagnosis Steps

1Checked the scaling event logs and found that new nodes were being provisioned slowly due to API rate limiting.
2Observed delayed pod scheduling as a result of slow node availability.

Root Cause

Slow cloud provider API response times and rate limiting.

Fix/Workaround

• Worked with the cloud provider to optimize node provisioning time.
• Increased API limits to accommodate the scaling operations.

Lessons Learned

Cloud infrastructure API response time can impact scaling performance.
