With most shared web hosting plans, root access is simply not available. The reason is due to the level of access given to the root account. The root account has unlimited access to all files, folders, and system configuration settings. Root access is required to start services on ports below 1024; you also need it if you want to compile and install programs or add modules to existing programs. In many ways, the root account on a Unix-like operating system is similar to the administrator account on Microsoft Windows.

At one time, the only way to get root hosting was to purchase a web hosting plan on a dedicated server. Since you are the only user of that computer, you can have unlimited access without affecting other users. The problem with this approach is the cost: dedicated servers can be very expensive whether you purchase one outright and pay for bandwidth usage or purchase monthly web hosting plan.

VPS hosting is the ideal solution for users seeking root access without the expense of a dedicated server. VPS Hosting technology uses a specialized virtualization platform/system that gives each user on a particular server their own operating system. Users enjoy the same level of unlimited root access but at much lower price than a dedicated server.

A VPS hosting plan offers the reliability and flexibility you need to provide solutions to your customers and clients.

Host your corporate/Business website on a powerful, reliable virtual private server and feel the difference. Use VPS hosting technology to protect your sensitive data and business information. There are no shared file systems on a VPS. As the administrator, you control what services to expose on your server. And it’s not problem to set up a firewall either.

Do you create web sites for clients?  Then save on hosting bills by hosting them all from a single VPS (with name based hosting).  Set up your development environment the way you want it, not the way some shared hoster wants it.

Use a VPS to provide failover services for your ‘main’ server. Who wants their site to disappear when your DNS goes down?  So, have your VPS provide secondary DNS. And if you use your VPS as a backup mail server, you’ll never miss an email again.

Is your main server backed up?  Who does it?  Are you sure they can recover your data from the backups?  Perhaps you need an extra copy.  Just in case. Choose a VPS plan with generous disk space and bandwidth allocations and make the ideal repository for your precious data.

What is VPS Hosting/Virtual Private Server:

VPS Hosting/Virtual Private Server offerings are a breakthrough Web hosting platform that looks and performs much like a full fledged physical dedicated server, with a price tag comparable to many shared server solutions. The Virtual Private Server is a one-of-a-kind Web hosting solution which is ideal for businesses with big needs, small budgets, and limited internal IT resources.

VPS Hosting offers the industry leading Virtuozzo Virtualization platform with the VPS technology to create a powerful and formidable Web site development and hosting solutions. The Virtual Private Server is a Web developer’s paradise - choose from applications like PHP, Active Server Pages (ASP), ASP.NET, Java, servlets/JSPs and more!

Benefits of having your own Virtual Private Server:

Virtual Private Servers were developed to provide many online businesses an affordable hosting solution without compromising on server performance, security, or flexibility. Because a dedicated server is too expensive for most businesses, but a traditional ’shared’ server does not provide enough freedom, The Virtual Private Server offering hits middle ground: Virtual Private Servers are a perfect fill-in between traditional shared web hosting and physical dedicated servers.

Virtuozzo’s patented Fair Share technology dynamically distributes resources between VPS servers on the same physical server.

Fair Share technology allows a host to set guaranteed minimum resource allowances for each type of VPS. At the same time, Fair Share technology gives each VPS access to unused physical resources. This way no single VPS server can monopolize Bandwidth, RAM or CPU resources and yet each VPS can maximize its performance by tapping into idle resources.

In practice, VPSs can burst far above guaranteed resource allowances for better overall performance while maintaining guaranteed performance levels. This is not possible with lesser VE technologies.

Dedicated Performance

Mainframe-like resource utilization, monitoring and control of hardware fully partitions each Virtual Private server. As a result, each VPS has full dedicated-server functionality: root access, ability to install any application or service, manage firewall, and even run different OSs - Red Hat, Debian, Suse, FreeBSD - on the same physical host. At the “root” level, a VPS server is virtually indistinguishable from a typical dedicated server.

VPS behaves exactly like dedicated server

* Has its own processes, users, files and provides full root access
* Has its own IP addresses, port numbers, tables, filtering and routing rules
* Has its own configuration files for the system and app software
* Use own versions of system libraries or modify existing ones
* Delete, add, modify any file, including files in /root, and install own application software or custom configure/modify root application software

A virtual private server (VPS hosting) solution uses a software platform that permits a hosting vendor to multiplex a single dedicated server into multiple “virtual” machines. In essence, a VPS solution is a private and protected Web services infrastructure that operates as an independent server.

A virtual private server allows multiple customers to share the expense of hardware and network connections without sacrificing privacy, performance or preference. For this reason, VPS is considered one of the most sophisticated modes of automation available for provisioning small to mid-sized enterprise Web hosting.

The use of such technology allows hosting providers to save money by simulating the features of a dedicated server multiple times upon a single physical hosting environment, while concurrently allowing them to deliver high-quality Web services to their end users. VPS solutions allow Web hosting resellers to provide a full range of services usually only afforded by dedicated hosting technology. Resellers can therefore offer their clientele full administrative or “root” access to their Web services.

The virtual private server was first implemented by hosting giant NTT/Verio to bridge the gap between shared hosting environments and customized dedicated servers. By using a virtual private server, Web hosting resellers and Web designers can provide small businesses the performance, security, and control of dedicated hosting services at a fraction of the cost.

A virtual private server eliminates the restrictions of virtual hosting by providing all of the administrative features of a dedicated server. Each VPS user therefore receives their own set of services that they can customize to their specific needs. Virtual hosting is limited in comparison because its users do not have root access and software configurations cannot be customized, despite the fact that physical resources are also multiplexed. A virtual private server on the other hand, contains its own unique file system and CGI-BIN, disk space, system resources, bandwidth and memory allotments, which allow for a high level of customization.

Due to the fact that a VPS solution truly simulates a dedicated server, some technical understanding of server administration is required. Any true VPS solution will provide users with: “root” or full administrative access; guarantee a specific allocation of server resources, including CPU, memory and bandwidth; and allow the user to manage multiple servers and file areas through a sophisticated control panel.

A virtual private server will ensure “performance isolation” so that heavy traffic or CPU loads will not affect other VPS solutions on the same infrastructure. Others major features that characterize VPS solutions include: “fault tolerance,” which ensures that errors, which affect one specific private server, do not affect others; and “enhanced security,” which ensures that e-business applications can be deployed with greater privacy.

The most popular feature that VPS customers use, however, is the virtual private server’s capacity for “functional isolation.” Because a VPS has its own contained services, it is possible for users to install and customize their own open-source and commercial software packages.

Many virtual private servers on the Unix platform have become so advanced that they even permit users to install Linux RPM packages. This allows users to take source code for new software and package it into source and binary form, such that binaries can be easily installed and tracked, and source can be easily rebuilt. The use of RPM packages also allows VPS users to maintain a database of all packages and their files that can be used for verifying packages and querying for information about files and/or packages.

Small businesses that run their own e-commerce Web sites also appreciate the functional isolation of their private server, because it allows them to obtain their own secure certificates and shopping cart software for their e-business operations. Many sophisticated VPS solutions will even offer third-party plug-ins or modules, allowing users to take advantage of control panel functionality in order to install everything from the simplest CGI scripts to the most advanced shopping carts.

Due to these advantages, virtual private servers are very popular and are a relatively inexpensive choice for small to mid-sized enterprises seeking to maintain their own Web presence. VPS solutions are the natural choice for SMEs and individuals wishing to upgrade a shared or virtual hosting package.

Types:
Virtuozzo is a commercial virtualization software which includes a GUI control panel.
OpenVZ is a GPL’d version of Virtuozzo (no GUI control panel).
Xen is GPL’d virtualization software (no GUI control panel)

Control Panels:
HyperVM is a control panel for either OpenVZ or Xen software.
GPLHost is a GPL’d control panel for the Xen software.

Xen will provide you 100% guaranteed access to the resources that are provided to your VPS. Meaning, you will ALWAYs have your 1GB of ram, regardless of what other VPSes are on the node itself.

OpenVZ and Virtuozzo on the contrary, excel at doing the so called “burst” which means, using a POOL of resources and spreading it between VPS’s in a node. You can also limit the use per VPS in OpenVZ, but not quite as Xen. OpenVZ is pretty close to Virtuozzo as they are related, the pluses to Virtuozzo are the templating system and the power panel.

OpenVZ and Xen use different virtualization approaches: OpenVZ uses OS level virtualization, while Xen uses paravirtualization. This is a pretty significant difference and proponents of each will argue it to their advantage. OpenVZ folks will say their approach allows for better resource usage and density. We feel paravirtualization provides good resource usage and superb isolation. Translation: your neighbor can’t bring the whole box down.

Xen also requires fixed memory and disk definitions, OpenVZ allows for burstable memory usage. That is the biggest difference you will see, burstable memory rates on Virtuozzo offerings, whereas Xen has hard, fixed caps. Burstable memory is great if you have control over all of the virtual servers (everyone is friendly), but when you have a diverse environment like ours, we prefer hard memory caps (you get what you pay for).

Operating a VPS provides you the advantages of dedicated server hosting without the associated costs! VPS hosting is therefore ideally suited for webmasters and power users who are experienced with dedicated server hosting. VPS hosting has a great economic advantage over dedicated servers if you are running a small number of websites and your websites are not resource intensive. If you have any problems with the Operating System in VPS, you simply reload it (or you can even install another copy of the OS, depending the system you are using).VPS hosting is ideal for websites with high resource needs, limited budgets, and limited internal technology resources. Even if hosting a powerful resource intensive process like E-commerce, VPS helps you build your website up and stay within your budget. VPS hosting is a low cost and lower maintenance approach to getting the functionality of a dedicated server. Through the special software installed on the server, accounts created on VPS are completely isolated from one another.

Minimum Software Requirements for using VPS :

The Hardware Node should run either on Red Hat Enterprise Linux 3 or 4, or Fedora Core 3 or 4, or CentOS 3.4 or 4. This requirement does not restrict the ability of OpenVZ to provide other Linux versions as an operating system for Virtual Private Servers. The Linux distribution installed in a Virtual Private Server may differ from that of the host OS.

Hardware Requirements for using VPS :

The Hardware Node requirements for the standard 32-bit edition of OpenVZ are :
1) Firstly, the computer should satisfy the Red Hat Enterprise Linux or Fedora Core hardware requirements.
2) IBM PC-A compatible computer is recommended.
3) CPUs: CPU used for VPS would be Intel Celeron, Pentium II, Pentium III, Pentium 4, Xeon, or AMD Athlon CPU. The more Virtual Private Servers you plan to run simultaneously, the more CPUs you need.

4) Memory: Minimum 128 MB of RAM. The more memory, the more Virtual Private Servers you can run. The exact figure depends on the number and nature of applications you are executing in your Virtual Private Servers. However, on the average, at least 1 GB of RAM is always preferable for every 20-30 Virtual Private Servers.

5) Hard Disk Drive: Minimum 4 GB of free disk space is recommended. Each Virtual Private Server occupies 400-600 MB of hard disk space for system files in addition to the user data inside the Virtual Private Server. It should be considered while planning disk division and the number of Virtual Private Servers to run.

6) NIC: Network card will be either Intel EtherExpress100 (i82557-, i82558- or i82559-based) or 3Com(3c905 or 3c905B or 3c595) or RTL8139-based are always preferable.A typical two-way Dell PowerEdge 1650 1u-mountable server with 1 GB of RAM and 36 GB of hard drives is suitable for hosting 30 Virtual Private Servers.

While deciding on the operating systems there are limitations. With a VPS, you are bind by the Operating System that the node is functioning on; for illustration, if you manage a VPS [Virtual Private Server] on a client which is created under Windows Server 2003, you can only bind to choose Windows Server 2003 as your operative group, and if you feature a VPS [Virtual Private Server] on a node which is working on Linux system then you can only change a Unix dispersion as your operative group.

Most of the vps hosting providers /web hosts tolerate you to install what Operating System you requirement, since you are usually provided with a virtual server which you can use to reload your VPS [Virtual Private Server] to any operating system template which is in the host’s grouping; however, most hosts do not allot the reloading of Windows servers since it must be through manually by the patron themselves.

The use for your VPS [Virtual Private Server]should ever be mirrored in the action of Operating System; you should go for a Linux supported VPS hosting Server. Your option of operating system strength also be impressed by the mirror of your VPS [Virtual Private Server]; for ideal if you get a VPS [Virtual Private Server] which is meant to be Windows supported that exclusive has 64mb RAM, then you won’t be able to run Windows since the minimum RAM needed for Windows Server 2003 is 128mb. This is the only requirement you will need to get with the Linux or Windows VPS.
