Building a production-grade application that scales isn't just about writing code; it's about creating a robust ecosystem where your frontend, backend, and infrastructure work in perfect harmony.
This guide provides a comprehensive blueprint for deploying a modern full-stack application using NestJS, Angular, Docker, and Kubernetes (EKS) on AWS.
The Core Architecture
Our setup follows a classic three-layer architecture designed for high availability and zero-downtime updates:
- Presentation Layer: An Angular 17+ Single Page Application (SPA), optimized for speed and served via AWS S3 and CloudFront CDN.
- Application Layer: A scalable NestJS 10+ API running within Amazon EKS (Elastic Kubernetes Service) pods.
- Data Layer: Persistent storage managed through RDS PostgreSQL for relational data and AWS S3 for object storage.
Why This Stack?
- High Availability: We use Multi-AZ deployments with auto-failover to ensure your app stays online.
- Smart Scaling: Horizontal Pod Autoscalers (HPA) automatically adjust your resources based on real-time CPU and memory usage.
- Efficiency: By utilizing containerization with Docker and orchestration with Kubernetes, we achieve consistent deployments across all environments.
- Production-Ready: The guide includes built-in monitoring with Prometheus, logging with Loki, and automated GitOps deployments via ArgoCD.
Infrastructure & Cost Planning
Deploying to the cloud requires careful budgeting. A standard production setup in the ap-south-1 (Mumbai) region typically ranges from:
- Low Usage: ~$466/month
- Medium Usage: ~$705/month
- High Usage: ~$1,025/month
Note: These estimates include EKS cluster fees, EC2 worker nodes, RDS instances, and S3 storage.
Key Technical Highlights
- Optimized Docker Images: We use multi-stage builds and Alpine Linux to keep images small (under 150MB) and secure.
- Security First: All containers run as non-root users, and we implement strict Network Policies and Pod Security labels.
- Automated CI/CD: A GitHub Actions workflow handles the heavy lifting—building images, pushing to Amazon ECR, and updating Kubernetes manifests automatically.
- Observability: Custom NestJS interceptors track HTTP request duration and total hits, feeding this data directly into Prometheus for real-time dashboards.
