# Demostration on using `aws-cdk` for Load-Balanced Fargate Service with RDS Database
This is a demo project for showcasing how to use `aws-cdk` to deploy a classic 3-tier web service with load-balancers, docker containers runnning application codes, and a relational database for persistant data.
We use AWS Elastic Load-balancer, AWS ECS Fargate for running Docker containers, and RDS Aurora for relational database.
| Tier | Componenet | AWS Service |
|------|------------|-------------|
| 1 | Load-balancer | AWS ELB |
| 2 | Application Logic | AWS ECS Fargate |
| 3 | Database | AWS RDS Aurora |
This projects uses a [simple express app with database connection](https://github.com/billykong/express-database-checker) for the application logic. You may need to replace the container image `billykong/express-database-checker` with your own Docker image if you want to reuse the template.
The `cdk.json` file tells the CDK Toolkit how to execute your app.
## Install AWS-CDK
```
npm install -g aws-cdk
```
## Useful commands
* `npm run build` compile typescript to js
* `npm run watch` watch for changes and compile
* `npm run test` perform the jest unit tests
* `cdk deploy` deploy this stack to your default AWS account/region
* `cdk diff` compare deployed stack with current state
* `cdk synth` emits the synthesized CloudFormation template
## Notes
- We should install the same version of `aws-cdk` and other `@aws-cdk/*` dependencies. It seems even minor version difference may be incompatible.
- This project uses `v1.38.0` for `@aws-cdk/*` and tested with `[email protected]`.
