The Truth About Hosting Virtual Servers on VMware vs Virtuozzo

The difference between VMware and Virtuozzo Containers is more than just a name. Just hosting companies using VMware can offer complete flexibility, security and capacity, as well as opportunities for high availability, load balancing and disaster recovery.

Operating System Flexibility

The main difference between VMware and Virtuozzo VMware to create an individual virtual server directly to the hardware, the bare metal level, while the Virtuozzo container run on the operating system (OS) level.

All container work environments on the same physical hardware must share the same operating system host. This means that, although each environment can start your own client OS, one can run on your virtual environment will be limited to those that are compatible with the host. Virtuozzo is limited to Linux or Windows and the host and client level, and can only run client OS on a physical server that uses the same host OS, in other words, the Linux client to a Linux host and Windows clients naWindows host. Of course, limiting the operating system also limits your choice of software available for Linux and Windows.

Running on the hardware level, VMware virtualization is realized by using the physical machine hardware resources to serve multiple virtual servers, each of which can run independent operating system. In this way, VMware virtualization supports many different operating systems on any server system. This enables VMware to support different versions of Windows and many different flavors of Linux, including Ubuntu, SuSE, Red Hat and, as a non-Windows and Linux operating systems such as Solaris and Netware.

With Virtuozzo, because the virtual environment must run the same OS as the host, you do not have the ability to manage and change their own operating sustav.Potreba for uniformity extends to update-all environments must be conducted on the same patch level. This means that if your virtual environment software is not optimized for the latest Windows or Linux update, and your hosting company to install it (on the main system and all virtual environments), your software may work poorly or not at all.

With VMware, you can manage and change their own operating system, as well as run various patch levels of the host system. This offers your company install and update the controls on virtual servers, as well as the freedom to use an expanded range of software, software for printing and even multiple software flavors on the same OS, such as the SQL standard, web, and Express editions.

In Virtuozzo containers, when you need to restart the virtual environment, such as during the test phase, you will have to wait for scheduled system power for an entire physical server, chaining you to your hosting company's calendar. Using VMware, you can restart your operating system, when and as often as the situation requires.

Finally, a hardware-based virtual servers such as VMware offers something OS-based virtual environment does not and can not offer virtual memory. Virtual memory is called swap in a Unix or page file in Windows, it enables your applications to use part of the allocated disk space as random access memory when it is necessary to avoid a fall. Since all the container environment shared by the core operating system, the containers do not have independent access to the swap. Using VMware, your hosting provider can give you the swap or paging files as large as it is available on a physical server.
