Market analysts from IDC released forecasts for the development of the virtualization services market. According to IDC the market will grow to $11.7 billion in 2011. Hardware virtualization (VMware, Hyper-V, XenServer), and application virtualization (SoftGrid/App-V, Citrix, VMware ThinApp) has been lead by VMware.

The producers of OS virtualization technologies like Sun, Parallels, iCore Software also increase their market share and rise and shift in virtualization recruitment trends.

An year ago in an article in CIO, the consulting firm Saugatuck Technology said that through 2013, management tools, processes, expertise, and services (not functionality) will remain the key limiting factor in user adoption of IT Virtualization. The company published report titled "The Many Faces of Virtualization: Understanding a New IT Reality".

The analytical firm predicts that by 2010, at least 30% of non-desktop IT infrastructure will be virtualized. This percent was less than 5% in 2007. Server and application virtualization lead the way.

Virtuozzo - One Step Ahead In OS Virtualization

by vpshostdir Email

Virtuozzo Containers is a truly great Os virtualization solution. It is proprietary software of Parallels and its software development principles are based on OpenVZ.

Unlike OpenVZ, Virtuozzo offers OS virtualization solution both for Windows and Linux OS. It creates isolated containers on a physical server and OS instance. The producer, Parallels says that compared to other virtualization technologies Virtuozzo offers "the highest levels of density, performance and manageability".

Virtuozzo Containers is compatible with x86, x86-64 and IA-64 platforms.

We said that Virtuozzo is based on OpenVZ. On of the advantage of the software architecture of Virtuozzo Containers is that it allows its users to share hardware and software licenses among different workloads.

We can say that Virtuozzo is probably the best choice for virtualization solution that any web hosting provider can choose. One of the main reasons for this is that it saves hardware and software resources by optimizes their usage. This allows web hosts to support hundreds of containers on a single server. Of course this does not mean that Virtuozzo should be used to corrupt the principles of VPS Hosting the way overselling hosts do in Shared Hosting.

Virtuozzo supports servers with up to 64 CPUs and 64 GB of RAM.

When a Virtuozzo user wants to use it under Windows Operating system as server OS, then all the Virtual Private Servers must also run the same version of Windows OS.

Linux users are offered more flexibility, because each VPS can run a Linux distribution different from the one of the host machine.

Virtualization method of Virtuozzo

Virtuozzo is a quite unique virtualizaton method because it virtualizes at the OS level, instead of at the hardware level. While other Virtual Machines (VMs) virtualize "a complete set of hardware", Virtuozzo virtualizes "an OS instance". So all Virtual servers created by Virtuozzo run atop a single OS kernel. The mechanisms of VPS creation multiplexes the OS kernel to look like multiple server (OS) instances.

The method of Virtuozzo causes lower overhead on the physical server than other virtual machine technologies, do. It relies on a single kernel and the VPS run the same kernel. All other applications - system libraries, configuration files, program files are different for can be different for each virtual server.

Virtuozzo saves providers resources and ensures fast-performance for VPS owners.

OpenVZ. Why It Is Important?

by vpshostdir Email

OpenVZ is an OS-level virtualization technology based on the Linux kernel and operating system. It can be described also as "container-based virtualization for Linux". OpenVZ creates multiple secure and isolated OS instances (containers, Virtual Private Servers (VPSs), or Virtual Environments (VEs)) on a physical server.

Compared to other virtualization technologies such as VMWare's approach and paravirtualization method used by Xen, OpenVZ is "limited" as fas as it requires the physical server (host) and the Virtual Private Servers (guest) to run Linux OS. Different Linux distributions can be used on the server and on each container.

OpenVZ - A Better Performance?

However, OpenVZ has one main advantage. It claims to produce better performance. The OpenVZ website says that "there is only a 1% to 3% performance penalty for OpenVZ as compared to using a standalone server. Test conducted from independent 3-rd party entities show that this evaluation is correct although some say that there are "more significant performance penalties".

OpenVZ's concept is in the core of one of today's world's leading commercial OS virtualization solutions (and one of the most popular Virtual Servers platform as a whole) - Virtuozzo Containers, a branded software product by Parallels.

It is Open Source!

The good news for web hosting entrepreneurs and software engineers interested in virtualization technologies is that OpenVZ is licensed under the GPL version 2, which means its basis can be used for the development of another virtualization software.

The OpenVZ's virtualization method to use Linux kernel and Linux OS enables better utilization of the hardware resources and avoids conflicts between software applications. Each container (VPS) runs as a stand-alone server. Containers (Virtual Private Servers) can be rebooted independently and their owners have root access, create users, have own IP addresses, memory, manage processes, files, applications, system libraries and configuration files.
