Cloud Native Application
Network Structures and Cloud Computing Course | December 2024
A cloud-native user management application leveraging Node.js, Express.js, and PostgreSQL to support concurrent requests with CRUD operations, health monitoring, and robust backend services. Designed for high availability and fault tolerance with fully automated CI/CD pipeline using GitHub Actions.
The Challenge
Building enterprise-grade cloud applications requires addressing multiple concerns:
- Scalability - Handling variable traffic loads without manual intervention
- High Availability - Ensuring the application remains accessible during failures
- Infrastructure Management - Consistent, repeatable deployments across environments
- Security - Protecting sensitive data and enforcing access controls
- Deployment Automation - Reducing manual steps and human error in releases
Key Features
Scalable User Management
Cloud-native RESTful user management application using Node.js, Express.js, and PostgreSQL, supporting concurrent requests, CRUD operations, and health monitoring.
Infrastructure as Code (IaC)
Provisioned AWS infrastructure using Terraform and Packer, deploying VPCs, RDS, Route 53, and SSL certificates for automated and scalable deployments.
Event-Driven Workflows
Integrated AWS SNS and Lambda for event-driven workflows, including automated email verification with SendGrid, ensuring seamless communication.
Security & Service Management
Secured services using Systemd for process management and enforced network security via AWS security groups.
Scalability & Auto Scaling
Enhanced performance with EC2 Auto Scaling and Elastic Load Balancing, optimizing traffic distribution and reducing downtime.
CI/CD Pipeline Automation
Implemented CI/CD pipeline using GitHub Actions, enabling automated testing, AMI creation, and rolling updates for seamless deployment.
