Multi-container Multi-zone App Deployment on AWS

Technologies used:

• VPC (subnets, security groups, internet gateway, routes)
• IAM (Roles)
• EC2 Instances (with ASG - Auto Scaling Group)
• Serverless compute (Fargate and Lambda)
• Container deployment with ECS and EKS
• Terraform (or drop in compatible OpenTofu)
• Dockers and containers

There are two apps - a backend REST API server and the front-end React app.

Backend app is written in golang utilizing gin framework (github.com/gin-gonic/gin for REST API routes) and YouTube Data APIs:

1. To collect YouTube channel metrics/stats
2. Walks through the list of videos on a channel
3. Find the video's metrics (views, likes)
4. Gets comments, and the user who commented
5. Does sentiment analysis (VADER - Valence Aware Dictionary and sEntiment Reasoner) on the comments.

Note: YouTube Data APIs are subjective to API Rate Limits.

Front-end is a very simple React GUI app.

Docker images built for both apps (backend and frontend):

• Tested standalone
• Tested by deploying on AWS with API Gateway + Lambda
• Tested by deploying on ECS:
  1. with EC2 (Auto Scaling Group) infrastructure
  2. Fargate serverless Infrastructure

Used Terraform to deploy on AWS.
