K8s Auto-Scaling System

Kubernetes Docker Helm Prometheus Grafana HPA

Project Overview

A highly resilient backend deployment orchestrated on Kubernetes. This project demonstrates advanced cluster management, including Horizontal Pod Autoscaling (HPA) driven by custom metrics.

The system effectively handles traffic spikes while optimizing cost by scaling down during low-activity periods.

Key Components

  • Containerization: Optimized Docker images for microservices, ensuring lightweight and secure runtime environments.
  • Helm Charts: Templated deployment configurations for consistent releases across different namespaces and clusters.
  • Monitoring Stack: Integrated Prometheus for metric collection and Grafana for real-time visualization of cluster health and application performance.
  • Auto-Scaling Logic: Configured HPA to scale pods based not just on CPU/RAM, but also on request latency and queue depth.

Impact

Achieved 99.99% uptime during high-load stress testing. The auto-scaling mechanism reduced cloud operational costs by approximately 30% by dynamically adjusting resource allocation.
