AWS Cost Optimization and Reliability Platform

A production-ready AWS infrastructure project that balances cost optimization with high reliability using automated controls, monitoring, and safeguards.

Architecture Overview

This solution implements a comprehensive cost optimization strategy while maintaining system reliability through:

Cost Controls: AWS Budgets with automated responses, scheduled Lambda functions for resource optimization
Reliability Safeguards: CloudWatch alarms for critical metrics, auto-scaling policies, multi-AZ deployments
Automation: Lambda functions triggered by budget alerts and schedules to optimize costs safely
Notifications: SNS topics for budget alerts, CloudWatch alarms, and operational events
Workload: Sample ECS-based application with auto-scaling and cost-optimized configurations

Key Components

Budget Management: Multi-tier budgets (monthly, service-specific) with threshold alerts
Cost Automation: Safe shutdown of non-production resources, ECS task scaling, S3 lifecycle policies
Reliability Monitoring: CPU, memory, latency, error rate, and storage alarms
Tagging Strategy: Consistent tagging for cost allocation and automation targeting
Security: IAM least privilege, encryption at rest/transit, audit logging

AWS Well-Architected Framework Alignment
