Server Infrastructure

Overview

Server Infrastructure using AWS and CDK.

AWS CDK Infrastructure package that creates:

1. Network Layer - Multi-AZ VPC with 3 subnets (1 public and 2 private-isolated)
2. Data Layer - Postgres Aurora database cluster and a Redis elasticache cluster
3. Service Layer - Fargate Service in an ECS cluster backed by an Application Load Balancer
4. CICD Layer - CodePipeline with 4 stages and a manual intervention.
5. Scripts - Scripts that assist in deploying and destroying

File organization

The infra sources are organized into the following files:

• package.json: Package dependencies for npm
• network-layer.ts: Construct to create a multi-AZ VPC with 1 public and 2 private isolated subnets.
• data-layer.ts: Construct to create a postgres aurora database cluster and a redis elasticache cluster.
• ec2-service-layer.ts: Construct to create an EC2 instance in an AutoScalingGroup fronted by an ApplicationLoadBalancer with a validated DNS certificate.
• fargate-service-layer.ts: Construct to create an ECS cluster with an ApplicationLoadBalancedFargateService and a validated DNS certificate.
• cicd-layer.ts: Construct to create a CodePipeline with a Source, CodeBuild, ManualApproval and ECSDeploy stages.
• stack.ts: Stack that creates above 4 constructs in the right order.
• init.sh Script to install node, cdk and npm dependencies
• bootstrap.sh Script to bootstrap CDK in a certain account and region.
• configure.sh Script to configure parameters and secrets in AWS.
• deploy.sh: Script to deploy the infrastructure in AWS
• destroy.sh: Script to destroy the infrastructure in AWS
• teardown.sh: Script to de-configure parameters, secrets and remove any remaining resources that CDK couldn't destroy.
• cleanup.sh: Script to remove dependencies and clean up infrastructure workspace
