Cloud Resume Challenge: Frontend

This is the Frontend of the Cloud Resume Challenge project by Forrest Brazeal.

• Project Article: "Semper Gumby: A Marine's Journey in the Cloud"
  • Project Website: https://DanWadleigh.dev
  • Project Backend Repo: CRC Backend
• The Challenge: Cloud Resume Challenge - AWS
  • DevOps Mod: Terraform Your CRC

Project Overview

The challenge was to build a secure full-stack serverless web app in the cloud. I built my project in AWS and also leveraged Terraform (IaC), GitHub Actions (CI/CD) and Cypress (Testing).

• Terraform Remote Backend Setup
• DNS and SSL Certificate Management
• S3 Static Website Hosting
• AWS CloudFront Distribution
• CI/CD Pipeline with GitHub Actions
  • Terraform deployment & management
  • S3 Sync of Website Code
  • CloudFront Cache Invalidation
  • Cypress End-to-End Testing

Key Features

• AWS Cloud Serverless with DevOps & Security practices.
• Terraform for infrastructure deployment and management.
• Serverless Frontend-Backend Integration
• Automation with CI/CD pipeline for reliable updates.
• End-to-End Testing of Website
• Monitoring and Alerting notifications

Tech Stack (Full):

• HTML, CSS, JavaScript
• IAM (User, Policies)
• S3 Static Website
• Amazon CloudFront
• AWS WAF
• AWS Certificate Manager
• Amazon Route 53, KMS
• Amazon API Gateway
• AWS Lambda, Python, boto3
• Amazon DynamoDB
• Amazon CloudWatch, Amazon SNS, AWS ChatBot
• PagerDuty, Slack
• S3, DynamoDB (Remote BE)
• Terraform (IaC)
• GitHub Actions (CI/CD)
• Testing (Cypress)

Project Mods

Completed additional DevOps and Security mods recommended for the CRC project.

• DevOps
  • Infrastructure-as-Code (IaC): provision & maintain infra with Terrafrom
  • CI/CD: deploy app via GitHub Actions with Cypress tests
  • Monitoring & Alerting: configured CloudWatch Alarms, SNS Topics with integrations to PagerDuty & Slack (AWS Chatbot)
  • Testing: implemented Cypress end-to-end testing upon deployment
• Security
  • DNSSEC: configured site domain name to protect DNS setup from potential spoofing
  • IAM Access Analyzer: configured IAM roles with least privileges required
  • Web Application Firewall (WAF): configured WAF web acl rule with CloudFront for both frontend and backend (API Gateway)
  • tfsec: static analysic security scanning of Terraform code in GitHub Actions workflow

Challenges (Real Learning)

• ACM: take note of us-east-1 locale
• IAM: access advisor vs practical GitHub Actions role permissions (apply before push)
• Remote Backend: create resources > migrate state to S3; s3 config - no vars allowed
• OIDC: create identity provider > then use with GitHub Actions
• State: manual terraform state usage (show, list, remove)
• API Gateway: v1 vs v2 differences; WAF requirements
• Variables/Outputs: referencing between main and modules
• SSM Parameter Store: ability to secure key info and share between projects
• Route 53: DNSSEC - establish chain of trust
• AWS Module: version consistency across project (pin version)
• locals: AWS Account ID
• WAF: CloudFront + API Gateway v2 (HTTP API)
• Docs: AWS & Terraform - growing ability to research and find solutions

Continuous Improvements

As I continue to learn, I see more opportunities to improve upon the project. At some point you just have to publish and take the learnings into the next project.

• Tests: add more quality tests
• Monitoring: add more relevant alarms
• WAF: observe and adjust the rules to further secure
• Tagging: add for billing visibility and misc config
• Performance: CI/CD and application in general
• Logging: capture as much info as needed to support
• Misc: code in general - what can be improved upon?

AWS Well-Architected Framework

• Operational Excellence
  • Automated deployments with CI/CD pipeline, monitoring, and continuous improvements.
• Security
  • IAM, Certificate Manager (SSL), and S3 bucket policies provide security of access and data.
• Reliability
  • S3, DynamoDB, and Route 53 ensure app availability and recoverability.
• Performance Efficiency
  • CloudFront provideds efficent content delivery.
• Cost Optimization
  • Specific resource (Serverless) provisioning with Terraform minimizes costs.
• Sustainability
  • Automation and optimizing AWS services reduce impact.
