DevOps Pipeline with Three-tier App

A three-tier application with Terraform, AWS ECS, AWS ALB, and CircleCI. The Terraform under the infrastructure directory creates a VPC, an AWS RDS instance with backups, and two web-based services–app and web–running in multiple AZs with an application load balancer in front of each, as well as a CloudFront (CDN) in front of the load balancer. Cloudwatch Logs were included for monitoring and alerting.
