Docker and virtual machines are both technologies used for virtualization, but they have some differences.<\/p>\n

    \n
  1. A virtual machine achieves virtualization by running a complete operating system on a physical server, whereas Docker achieves virtualization by running containers on the host operating system.<\/li>\n
  2. Virtual machines typically require more resources because each virtual machine needs a complete operating system, while Docker containers share the host operating system’s kernel, resulting in lower resource consumption.<\/li>\n
  3. Docker containers have faster startup times and better performance because they do not need to start a full operating system.<\/li>\n
  4. Docker containers are lighter, take up less storage space, and deploy faster.<\/li>\n
