What is this Product?ΒΆ

This product is an Auto-Scaling Solution implemented via a Helm Chart for Kubernetes. It integrates with Prometheus and Kubernetes Horizontal Pod Autoscaler (HPA) to provide automatic, application-aware scaling of your workloads based on metrics.

The Pain Point It SolvesΒΆ

Traditional Kubernetes HPA Limitation πŸ›‘:ΒΆ

Kubernetes Horizontal Pod Autoscaler (HPA) natively scales based on CPU and Memory usage only. However, modern applications often require scaling based on:

  • πŸ“Š Requests Per Second (RPS)
  • ⏱️ Latency (e.g., P95, P99)
  • πŸ“₯ Queue Backlog or Job Depth

The Solution: Auto-Scaling Helm ChartΒΆ

This product provides a Helm Chart that integrates the following components to solve this limitation:

Custom Metrics Integration:ΒΆ

  • The product integrates with Prometheus and Prometheus Adapter to fetch custom application metrics.
  • These metrics (e.g., requests per second, latency, queue depth) are exposed by the application and scraped by Prometheus.

Automatic HPA Configuration:ΒΆ

The Helm Chart configures Kubernetes HPA to use: - Resource Metrics (CPU/Memory). - Custom Metrics (application-specific metrics). - External Metrics (e.g., message queue depth).

Production-Ready Features:ΒΆ

  • RBAC Support: Ensures Prometheus Adapter and HPA have proper permissions.
  • Health Checks: Ensures Prometheus, Prometheus Adapter, and the application are healthy.
  • Modular Deployment: Allows integration with existing Prometheus setups or installs new Prometheus if needed.
  • Scalability: Handles scaling of multiple workloads across namespaces.

Key Pain Points SolvedΒΆ

Scaling Beyond CPU/Memory:ΒΆ

Applications can now scale based on: - Requests per second. - Latency (e.g., P99). - Queue length or backlog.

Simplified Deployment:ΒΆ

The Helm Chart provides an automated, production-ready setup: - Install Prometheus and Prometheus Adapter (if not already available). - Configure Kubernetes HPA to leverage both default and custom metrics.

Improved Application Performance:ΒΆ

By scaling based on real application behavior (e.g., high latency or load), the product ensures better performance and availability.

Flexibility for Any Application:ΒΆ

Works with any application that exposes metrics in Prometheus format on a /metrics endpoint.

Time and Cost Savings:ΒΆ

  • Automates the manual scaling of applications.
  • Optimizes resource utilization, reducing cloud infrastructure costs.

Who Needs This Product?ΒΆ

Developers & DevOps Teams:ΒΆ

Looking for flexible scaling of applications in Kubernetes based on metrics like request load, queue size, or latency.

Businesses Running Critical Applications:ΒΆ

Ensures the application scales quickly and efficiently during high demand, preventing downtime or degraded performance.

Organizations Using Microservices:ΒΆ

Microservices often rely on multiple metrics (like request rate and latency) for scaling decisions. This product simplifies scaling for these architectures.

In SummaryΒΆ

This product addresses the gaps in Kubernetes HPA by enabling application-aware scaling with custom and external metrics. It automates the setup with a Helm Chart, reducing operational overhead and ensuring better resource utilization, cost-efficiency, and performance for Kubernetes workloads. πŸš€
