Highlights

~30%

Reduction in GKE Node Compute Costs

100%

Automation of Node Pool Scaling Operations

240-300 hrs/month

Unnecessary Node Runtime Eliminated per Node

The Challenge

The client’s GKE environment incurred unnecessary infrastructure costs as selected node pools remained active beyond application operating hours. Manual scaling was inefficient, and varying node pool configurations required a reliable, automated approach to optimize costs without impacting critical workloads.

Solutions

• Implemented automated GKE node pool scale-down and scale-up.
• Used Cloud Scheduler and Pub/Sub for scheduled, event-driven scaling.
• Deployed Cloud Functions Gen 2 to manage scaling operations.
• Restored node pools automatically before business hours.
• Enabled secure access, monitoring, logging, and alerting through IAM and Google Cloud observability services.

The Results

Achieved a 30% reduction in compute costs, eliminated unnecessary node runtime during non-operational hours, and fully automated node pool scaling, reducing manual operational effort while improving infrastructure efficiency.
