Container

Simply put, HyperContainer is a virtualized container technology that allows you to run Docker images on hypervisor (KVM, Xen, etc.):

HyperContainer = Hypervisor + Docker Image

By combining the best from both virtualization and container world, HyperContainer is able to bring the hardware-enforced isolation as VM, and the speed of container.

ISOLATION	Strong	Weak	Strong
PORTABLE	No	Yes	Yes
BOOT	Slow (seconds)	Fast (sub-seconds)	Fast (sub-seconds)
IMMUTABLE	No	Yes	Yes
IMAGE SIZE	Big GBs	Small MBs	Small MBs
EXISTING INFRASTRUCTURE ROI	-	No	Great
TOOLCHAIN MATURITY	Great	Brand new	Great

Container Resource Limits

• Max open files: 1000000:1000000

• Max processes: 30604:30604

• Max pending signals: 30604:30604
