Overview

This project involved designing and deploying a robust cloud infrastructure to support modern web and mobile applications with high availability, performance, and security in mind. The infrastructure was architected to be fully scalable, automated, and cost-efficient — leveraging Infrastructure as Code (IaC) and modern DevOps practices.

As the lead on this project, I handled everything from provisioning virtual machines to setting up CI/CD pipelines, configuring monitoring tools, and ensuring the system met both performance and security requirements.

Key Components

Infrastructure as Code (IaC)

  Utilized Terraform to provision and manage cloud resources across AWS, ensuring repeatability, version control, and automated environment setups.

Compute & Networking

  Set up EC2 instances, Auto Scaling Groups, Load Balancers, and configured VPCs with public/private subnets, NAT gateways, and security groups for controlled traffic flow.

Storage & Databases

  Provisioned and secured S3 buckets for object storage, and deployed RDS (PostgreSQL/MySQL) for managed relational database services with automatic backups and failover.

CI/CD Pipelines

  Built CI/CD pipelines using GitHub Actions and Jenkins, automating testing, container builds (Docker), and deployments to staging and production environments.

Containerization & Orchestration

  Containerized apps with Docker, and deployed them using Kubernetes (EKS) for auto-scaling and high availability.

Monitoring & Logging

  Integrated Prometheus, Grafana, and CloudWatch for real-time system metrics, alerting, and comprehensive log analysis.

Security

  Implemented IAM policies, encrypted storage, secrets management via AWS Secrets Manager, and HTTPS via AWS Certificate Manager + CloudFront.
