Docker 0.9 Moves Beyond Linux LXC Containers for Virtualization
Page 1 of 1
The open-source Docker Linux container project is continuing its march toward broader deployment with the release lof Docker 0.9 on March 10 and the announcement of a Linux container certification effort from Red Hat.
Docker leverages a container approach to virtualization, which is fundamentally different from the traditional hypervisor virtual machine model used by VMware's ESX, Microsoft's Hyper-V, and the open-source Xen and Kernel-based Virtual Machine (KVM) projects. Instead of requiring an entire operating system to be virtualized, as is the case in the hypervisor model, Docker virtualizes applications in containers that sit on top of a host operating system.
