Open-Source Docker Container Virtualization Turns One
Page 1 of 1
The Docker open-source virtualization container technology project celebrated its one-year anniversary on March 20, as the project stands on the precipice of significant growth in 2014.
Docker represents a different model for virtualization than the traditional hypervisor virtual machine (VM) approach espoused by VMware's ESX, Microsoft's Hyper-V, Xen and the open-source KVM (Kernel-based Virtual Machine) technologies that are already widely deployed in data centers around the world. With a traditional hypervisor, each VM needs its own operating system. In contrast, with Docker, applications sit inside a container that resides on a single host operating system that can serve many containers.
The Docker technology carries with it a tremendous amount of promise and excitement.
