When reading about virtualization, it's often easy to get lost in the masses of possible meanings given to the word by various sources. We now present you with container-based OS virtualization, providing an alternative solution - one that's quite regularly overlooked, despite its merits. We hope it gives you a clear overview of the possibilities this technology offers, as we go in-depth into what makes it tick.
How Does It Work? To get started, a clear view of what the system “looks” like is needed. Unlike hypervisors and application virtualization solutions, the isolation happens inside the actual OS layer, where certain additions are included to allow for the isolation of each OS subsystem. Every container is essentially no more than a shielded part of the host OS.
