DevOps Infrastructure Case Study (Ongoing)
Project Overview
The DevOps Infrastructure project is a personal initiative that focuses on creating a scalable, secure, and efficient environment for hosting multiple applications. Leveraging cloud computing principles, the infrastructure integrates advanced technologies like Docker, Docker-Compose, and GitHub Actions to automate deployment pipelines and ensure seamless CI/CD processes. All contributions are my own, including developing key automation scripts, configuring DNS for optimized routing, and implementing a secure server management system via SSH.
Technologies and Tools Used
Development Phases
The development of the DevOps infrastructure followed a structured approach, focusing on implementing robust and scalable solutions for hosting and deploying applications securely.
Phase 1: Infrastructure Design
- Designed a VPS-based network architecture to host multiple applications.
- Planned dual-purpose infrastructure for student experimentation and app deployment.
- Defined containerization requirements for application isolation and security.
Phase 2: Automation and CI/CD
- Integrated GitHub Actions for continuous integration and delivery (CI/CD).
- Developed automated workflows to streamline deployments using Docker-Compose.
- Optimized deployment pipelines for scalability and efficiency.
Phase 3: DNS and Routing
- Configured DNS for efficient routing and improved accessibility of hosted applications.
- Ensured domain name resolution was consistent across all services.
- Managed DNS updates for high availability and minimal downtime.
Phase 4: Secure Server Management
- Implemented SSH for secure remote access to the server.
- Automated server updates and system maintenance using Linux command-line tools.
- Monitored server performance and logs to ensure system integrity.
Phase 5: Testing and Deployment
- Deployed applications like AstroMao, Book Tracker, phpMyAdmin (also used by classmates) in isolated containers.
- Conducted testing to verify system performance and reliability.
- Published containerized apps on Docker Hub for easier distribution and reuse.
Conclusion
The DevOps Infrastructure project demonstrates the power of automation, scalability, and secure practices in modern software development. By leveraging open-source and custom technologies, this infrastructure provides a dynamic environment for programming experimentation and robust deployment capabilities, ensuring efficiency, security, and flexibility for a variety of use cases.
