LINUX CONTAINERS

Software packaging concept that typically includes an application and all of its runtime dependencies.

● Easy to deploy and portable across host systems

● Isolates applications on a host operating system. In RHEL, this is done through:

● Control Groups (cgroups)● kernel namespaces● SELinux, sVirt

PLATFORM OF CHOICE FOR PERFORMANCE BENCHMARKS

Performance is easily twice as fast under Red Hat Enterprise Linux. We also reduced our total hardware & operating system licensing costs by 25 percent. I’d say that the case for Red Hat Enterprise Linux is an open and shut one.
