How do containerization technologies like Docker influence server deployment and resource management, compared to traditional virtual machines?

Containerization technologies like Docker encapsulate applications and their dependencies into containers, which share the host OS kernel but run in isolated environments. This approach offers faster deployment, lower overhead, and more efficient resource utilization compared to traditional virtual machines, which require a separate OS instance for each VM. Containers also facilitate continuous integration and deployment (CI/CD) practices, enhancing development agility. However, they require robust orchestration tools like Kubernetes to manage complex deployments and ensure scalability and reliability.
