It’s impossible to read about cloud without reading about hypervisors and virtual machines; virtualization is at the heart of cloud. And for most, that means hypervisor-based full virtualization — where a host operating system and hypervisor run VM partitions, like independent servers, with their own OS and middleware. However, virtualization casts a wide net that can be valuable in the cloud. And that net contains a popular virtualization model — container technology.
In the container model, a server runs an OS that creates semi-autonomous containers to load applications. These apps share the OS or host, so servers don’t run a new OS copy for each VM. Containers stand between independent VMs and simple multi-programming and offer some application isolation — but not full separation…
Containers often are a better approach for private cloud and some public cloud applications. Docker, the most popular container architecture, may be the perfect platform…
