12. Conclusion
Building a modern IT infrastructure requires leveraging a suite of open-source tools that work together to streamline development, deployment, monitoring, and management. With Kubernetes for orchestration, Docker for containerization, Jenkins or GitLab CI/CD for automation, Prometheus and Grafana for monitoring, and the ELK/EFK stack for logging, you can create a powerful, scalable, and cost-effective tech stack. Tools like Ansible and Terraform further simplify configuration management and infrastructure provisioning, while Apache Kafka enables robust real-time data processing.
Understanding not only the capabilities of these tools but also their origins—such as Kubernetes from Google (2014) and Docker from Docker, Inc. (2013)—provides valuable context that can guide your decisions as you build and optimize your infrastructure.
