This repository offers a template for deploying microservices on AWS, leveraging Application Load Balancer (ALB) and Elastic Container Service (ECS).

• Infrastructure Management: Utilizes the AWS Cloud Development Kit (CDK) in TypeScript for robust Infrastructure as Code (IaC) capabilities.
• Traffic Routing: Employs an Application Load Balancer (ALB) to direct traffic to separate microservices.
• Path-Based Routing: Configures the ALB to route traffic based on URL paths (e.g., /api/users*) for targeted service delivery.
• Security & TLS: Features dual ALB listeners for HTTP (port 80) and HTTPS (port 443), with HTTP traffic automatically redirected to HTTPS via AWS Certificate Manager for secure TLS encryption.
• Container Orchestration: Deploys microservices on ECS, orchestrating Docker containers for optimal resource utilization.
• Serverless Compute with Fargate: Utilizes AWS Fargate for serverless compute, allowing for the automatic scaling and management of containers without the need to provision or manage servers.
• Resource Allocation: Allows customization of resource allocation (CPU, memory) for each microservice.
• Dynamic Scaling: Implements auto-scaling for microservices based on various metrics like CPU usage, memory usage, and request count.
• Microservice Example: Includes a TypeScript microservice example demonstrating rapid builds with Bun (<1 second) compared to traditional tools like Webpack (~40 seconds).
• Performance Optimization: Uses Bun runtime in Docker images for enhanced performance of the example microservice.
• Docker Image Hosting: Docker images are stored on Amazon Elastic Container Registry (ECR).

1. Install Dependencies: Execute bun install to install required packages. This project uses Bun as its package manager.
2. Configure Environment: Populate the .env file with necessary environment variables, referencing .env.example for the template.
3. CDK Bootstrap: If your AWS account and region have not been prepared for CDK deployment, run cdk bootstrap to set up the necessary environment.
4. Deploy the Stack: Use bun run deploy for deployment. Ensure the Docker daemon is active, as the CDK stack automates Docker image building.
5. DNS Configuration: After deployment, configure your domain's DNS settings by pointing a record to the Application Load Balancer's DNS name to route traffic to your application.
