Docker is a containerization platform that packages code, dependencies, and environment into isolated containers, ensuring consistent behavior across different environments.
Key differences between Docker deployment and traditional deployment include one-command setup with isolated environments in Docker, while traditional deployment involves manual setup with system-wide dependencies.
Docker provides clean isolation, easy cleanup, and consistent setups, whereas traditional deployment can lead to system-wide clutter and environment mismatches.
While Docker may have a slight overhead compared to traditional deployments, it offers benefits like environment-specific debugging and reproducible environments, making it ideal for building scalable and modern applications.
