Deploy a Production Microservices App on AWS ECS Fargate | Private Subnets, ALB & RDS PostgreSQL
🚀 In this project, we build and deploy a complete production-style microservices application on AWS using ECS Fargate, Application Load Balancer, Amazon RDS PostgreSQL, ECR, Secrets Manager, NAT gateway, VPC Endpoints , Docker, React, and FastAPI
Instead of deploying applications directly on EC2 instances, we containerize our services, push images to Amazon ECR, and deploy them using ECS Fargate in a secure architecture with private subnets and a public Application Load Balancer.
Throughout this project, we cover both the practical implementation and the architecture concepts required to understand how real-world cloud-native applications are deployed on AWS.
