Project Summary

Congratulations on completing the capstone project! One of the most critical next steps is to create comprehensive project documentation that captures the entire TerraStack 3‑Tier journey. This documentation will serve a dual purpose:

  • As a portfolio showcase, highlighting your technical expertise and problem‑solving approach.
  • As a reference guide, providing valuable insights and reusable knowledge for future projects.

Documentation Structure

  • Project Overview:
    • Name: TerraStack 3‑Tier
    • Goal: Deploy a 3‑tier application infrastructure using Terraform.
  • Architecture Diagram:
    • VPC, subnets, gateways, security groups.
    • Web, App, DB tiers.
    • Load balancer entry point.
  • Implementation Steps:
    • Networking: VPC, subnets, gateways, SGs.
    • Compute: EC2 instances, launch templates, auto‑scaling.
    • Database: RDS with private subnets, backups, multi‑AZ.
    • Load Balancer: ALB with listeners, target groups, health checks.
    • CI/CD Pipeline: GitHub Actions/Terraform Cloud integration.
    • Debugging: Common errors and fixes.
  • Code Snippets:
    • Key Terraform resources (VPC, EC2, RDS, ALB).
    • CI/CD pipeline YAML.
  • Challenges & Solutions:
    • Example: State lock conflicts → solved with Terraform Cloud remote state.
    • Example: Resource drift → solved with terraform refresh.
  • Final Outcome:
    • Screenshots of deployed infrastructure.
    • Pipeline run logs.
    • Successful health check results.

Learner Action Challenge

      • Lessons learned (debugging, collaboration, automation).
      • Screenshots/diagrams of final infrastructure.
  2. Publish on LinkedIn:
    • Share the article as a LinkedIn post.
    • Tag Happywala Engineer to join the community conversation.
    • Use hashtags: #Terraform #DevOps #CloudEngineering #HappywalaEngineer.
  3. Engage with Peers:
    • Comment on others’ posts.
    • Share feedback and insights.
