Docker

Docker revolutionized deployment and CI/CD with containerization, supporting 12+ million active containers daily. Launched in 2013 by Solomon Hykes, it achieves 70%+ enterprise adoption—cheaper than the typical rival solution, reducing infrastructure costs by an average of 55%. Each container packages code with all dependencies, eliminating environment discrepancies and outperforming #8 Node.js in deployment consistency. Docker’s layered image system saves developers 30% of setup time versus virtual machines, making it the backbone of modern cloud-native workflows.
