Hypervisors have dominated the landscape of virtualization, but they aren't the only dog in the yard. Container-based virtualization uses a single kernel to run multiple instances on a single operating system, which is a much more secure option. It also can be a better option in terms of efficiency because it handles resources intelligently instead of letting them be misused or underutilized.
Before your company chooses hypervisors, it's important to compare them and container-based virtualization to see which makes more sense. Parallels Virtuozzo and OpenVZ are just two options for container-based virtualization, and both go in unique directions with how they approach virtualization.
These five quick links will help you gain some knowledge about container-based virtualization and how it could be a fit for you:
The argument for choosing container-based virtualization
Hypervisors are the easy choice, so why should you even consider using something different? If you're using just one operating system, container-based virtualization offers better performance and efficiency than hypervisors.
Creating cgroups to run smoothly and stay efficient
Containers are a great way to group resources, but if they aren't set up correctly, they could disrupt performance and lower efficiency. Cgroups help limit the resources that containers have available to them, allowing for better performance.
A different virtualization player with a unique approach
It's not all about just VMware, Microsoft and Citrix XenServer. Parallels Virtuozzo uses a different approach to virtualization, one that's focused on the operating system and that isolates containers to maximize efficiency.
Creating a virtual machine with OpenVZ
Find out how to create a virtual machine (VM) with OpenVZ, a container-based virtualization product that runs on Linux. Container-based virtualization is an alternative to hypervisors, and can benefit your organization if it's the right fit.
OpenVZ's different approach has limitations
One of container-based virtualization's best perks is how secure it is because every VM runs completely isolated from the VMs in other containers. OpenVZ uses a different approach than most, but it has one major limitation -- the operating system and the virtual guest operating systems must run Linux.
