Why DevOps & Cost Optimization Matter

Cloud infrastructure costs grow exponentially without active optimization. Organizations typically overspend by 40-60% on computing due to:

  • Misunderstanding pricing models
  • Inefficient resource allocation
  • Lack of automated cost monitoring
  • Poor infrastructure design patterns

This hub provides production-ready patterns, real-world examples, and implementation guides for:

  • AWS cost optimization (Reserved Instances, Savings Plans, Spot Instances)
  • Serverless cost management (Lambda billing traps, DynamoDB optimization)
  • Container cost analysis (Docker, Kubernetes, ECS spending)
  • FinOps automation (CloudHealth, Kubecost, cost governance)
  • Multi-cloud strategies (cost arbitrage, vendor selection)
