Network Bandwidth Saturation During Large-Scale Deployments

Network bandwidth was saturated during a large-scale deployment, affecting cluster communication.

Find this helpful?

What Happened

During a large-scale application deployment, network traffic consumed all available bandwidth, leading to service timeouts and network packet loss.

Diagnosis Steps

1Monitored network traffic and found that the deployment was causing spikes in bandwidth utilization.
2Identified large Docker images being pulled and deployed across nodes.

Root Cause

Network bandwidth saturation caused by the simultaneous pulling of large Docker images.

Fix/Workaround

• Staggered the deployment of pods to distribute the load more evenly.
• Used a local registry to reduce the impact of external image pulls.

Lessons Learned

Ensure that large-scale deployments are distributed in a way that does not overwhelm the network.
