What is Virtual Private Server (VPS)?

Virtuozzo creates multiple isolated Virtual Private Servers (VPSs) on a single physical server to share hardware, licenses and management effort with maximum efficiency. Each VPS performs and executes exactly like a stand-alone server for its users and applications as it can be rebooted independently and has its own root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files.

* VPS performs and executes exactly like an isolated stand-alone server
* Quality of Service to provide dedicated SLAs for each VPS
* Virtual Private Servers (VPS) is not a Virtual Machine (VM)!
* VPS runs off-the-shelf software without any changes

If you are looking for greater control and performance than a Shared Hosting account can provide, or a low-cost upgrade path to a Dedicated Server,  Linux VPS Hosting deliver dedicated-sized performance at a fraction of the cost. They come with exactly the same features, autonomy and functionality of a dedicated Linux server, and are suitable for a wide range of tasks such as application testing/development, multiple virtual domain hosting, high traffic websites or game serving.

Designers & Resellers

We know what web professionals need in order to deliver a quality hosting service to their customers. A VPS offers resellers a blend of highly reliable, low-cost dedicated resources, and a powerful interface with which to administrate their clients’ domains, email, and manage other configuration tasks. You can choose to use the Control Panel to achieve this, or to configure your VPS yourself with root access solution.

Game Developers and Game Serving

The online gaming revolution has arrived with the take-up of broadband, and now thousands of players regularly compete and team up online in games such as Half-Life and Counterstrike. Of course, to be able to host your own games, you need to run your own server, which is not only costly, but you are usually tied into an annual contract. VPS Root changes that - as you have root access to a virtual private server, you can use our HL/CS packages or install your own games and frag away to your heart’s content!

Application Developers

Whether you are testing software, building a complex, database-driven application, or working on a bespoke development project, a VPS Root package is an ideal midway-point between shared hosting, with its inherent compromises, and dedicated hosting which may be too costly. Virtual Servers are highly practical for short-term, pre-launch projects.  Post-launch, operations can move to a similarly structured dedicated solution, literally in minutes.

Learn Common Web Used Terms for VPS Hosting Account Plans

* Apache - A web server program. Apache is one of the world’s most popular web server programs, it was built and is maintained by a group of open source programmers and it is often used because of it’s excellent performance, security features and that it is free.

* Bandwidth - The amount of data that can be transferred at a given moment to or from a server. The larger the bandwidth value the higher amount of traffic your site can handle at one time.

* Burstable Memory - Refers to the amount of memory that your virtual machine can use if you run out of your “Guaranteed Memory”. Burstable memory is available only if there is free memory available on the VPS node.

* Command Line - This resembles DOS in that it is just a blank screen with a prompt where the administrator/user would type in commands for the system to run. Most users would rather use a web base interface or a graphical interface to administer their system because there is less chance of error.

* Control Panel - A web based interface, which allows users to administer their server by clicking on different icons instead of having to memorize commands. The commands would be run on the command line and if typed in incorrect they could seriously harm a system and stop it from running forcing the hosting company to have to restore the system from a backup.

* cPanel - CPanel is a fully featured web-based control panel that allows you to manage your domain through a web interface. The idea is to transfer as much of the control and responsibility of managing your web site to you. You have the ability to manage all aspects of e-mail, files, backup, FTP, CGI scripts, and web site statistics.

* Dedicated Hosting - This hosting feature allows a web site to have its own server. It is more flexible than shared hosting as webmasters have full control of the server, including choice of operating system. Server administration is still taken care of by the hosting provider.

* Fantastico - An integrated application that allows web hosting clients to automatically install popular scripts.

* File System - A system of storing files on the hard drive and in this case the files are stored in such a way that only your account(s) have access to them. This is more secure than shared hosting where everyone is on the same file system and could go look in other areas where they should not be.

VPS Hosting vs Shared Hosting

* Performance - In a shared environment resources goes all websites in an unequal manner. In other words, a big site can drain all resources and leave yours performing sluggishly. In a virtual private server environment, you are guaranteed a set of resources to ensure your site always performs at full speed! These resource guarantees ensure other virtual private servers have no affect on the performance of your site.

* Control - A virtual private server or virtual dedicated server or VPS hosting account gives you full root access to the system. This will allow you to modify server configuration files, install applications or modify system software should you require or need to. In a simple shared environment, you will have to rely on server settings that are pre configured and fixed for all clients.

* Security - With a virtual private server or virtual dedicated server or VPS hosting your file system is not accessible or viewable by any other VPS owner, unlike a shared environment where anyone with shell access can browse through your files a VPS ensures full privacy and security.

* Isolation - In a shared hosting or cpanel shared hosting or Linux windows shared hosting environment you are susceptible to system crashes and vulnerabilities created by the actions of others. If another shared account runs a script that crashes the server or opens up severe vulnerabilities, your site will go offline or be hacked as well. With a VPS account, you will have complete resource isolation, no matter what another VPS user does it will not affect your server.

All of the above are also valid reasons to move to a dedicated server. However running a dedicated server can be time consuming and technically difficult, it also assumes you need the full power of a dedicated server and this is what makes virtual private servers so good, all the benefits, at a resource level you need and at a fraction of the cost!

Guranteed Memory

VPS Hosting or Virtual Private servers are used to get multiple servers connected to get maximum number of servers for all the users. This is done by virtually splitting the physical server into logical servers so that each server is capable of independent execution. This is mainly used to reduce the cost incurred in procuring many physical servers. Each server in the virtual environment has its own operating system and so they can be rebooted on their own. The VPS is mainly useful in a scenario of web site hosting where each user or client needs a server on their own.

When hearing about VPS, there are two main doubts that come into the mind of any individual. These are guaranteed memory and burstable memory. In the simplest definition, guaranteed memory is the allowable memory for use in a VPS. It can be used whenever the user wishes. The memory allocated in VPS will vary. But the portion of the memory which can be put to use for functioning in VPS is generally called by the name guaranteed memory.

Guaranteed Memory never claims that you can’t use memory more than that prescribed value. Rather it is the least amount that you can make use of. This is independent for each VPS connected to a single physical server. That is, even when the guaranteed RAM available for a virtual server is exhausted, it never affects any other server in the system. And the guaranteed RAM for each virtual server can be made use of at any time completely isolated from other servers in the system.

Guarantee RAM always refers to in the case of actual usage. That is if the required use of memory for the working is less than the guaranteed memory, then the memory can be put to use to the maximum limit. This is because the actual use is less than guaranteed memory.

Guaranteed RAM often remains the prime criteria for your selection of VPS services. So make sure that the memory guaranteed is sufficient for your use. This is because often the companies claim a high availability of RAM, but the net available RAM will not be enough for your use. Performance of VPS is directly proportional to the available guaranteed memory. So this should be the condition for choosing in the case of VPS hosting.

Guaranteed RAM plays a significant role in the selection of the platform also. It is always advisable to understand the memory guaranteed by Linux and Windows before making the platform chosen for VPS hosting. There are specific servers that help to burst the guaranteed RAM for use as burstable RAM which makes the total memory availability more.

Windows VPS Hosting

If the web site has Access as the database, Linux won’t suit for the design of that web site. Access is intended and designed to work with Microsoft. Hence in Linux web sites you have no option to work with Access databases.

Another restriction is in the use of MSSQL. It is designed specifically for Microsoft Windows. Linux provides various enterprise databases. But those users who want to go for MSSQL will have to choose Windows for VPS hosting.

SharePoint services of Microsoft can be used only in Windows. Front page 2003 can be used only in Windows platform. Hence Linux users can’t use these features and so they will have to opt Windows VPS hosting.

But when the expense is really that matters, it is always good to use Linux. The Enterprise web sites will be more effectively executed in Linux. PHP works well with Linux. Most busy web sites are created out of Linux. This is because of the infra structure that comes with Linux. The ease of use and the facilities of Microsoft are unavailable. But small business men usually prefer to go for Linux in their web site hosting.

Because of the user friendliness that Windows provide, most users who are unskilled in the hosting service will go for Windows as their platform for VPS hosting. The Microsoft features are so advanced that even a novice user can host a web site. But the cost usually pulls back the people from doing so. The choice is entirely based on the purpose and the functionalities that we expect from the web site.

Advantages of VPS Hosting

VPS is the technique of creating multiple virtual private servers out of a single physical server. The single server is logically partitioned into many logical servers that can execute independently as real servers. These servers are given resources dedicated to each and they are capable of running on their OS. All features of real servers are duplicated in the virtual private servers made out of them.

VPS hosting offers a lot of benefits to the small and medium business owners. The main advantage of VPS hosting is the ability of each vps server to execute independently. The vps servers run on their own OS and resources. Each vps server has no access to the resources or software running on any other server connected to the same physical server. So when there is any problem in the working of one of the vps servers, the total performance is never affected. Only the affected vps hosting server needs to be halted and all others continue delivering their service.

One of the main advantages of using VPS is the reduced cost in obtaining multiple physical servers. The expense required to get multiple resources and network can be lessened as the physical server is virtually partitioned. Each vps server has all the functionalities of a real server but at the same time there is no need of getting the real server for use. This is mainly beneficial when the servers of architecture like mainframe are too costly to buy. There you can emulate the servers and reduce the over all expense.

VPS Hosting are also sometimes employed to provide honeypots, allowing a machine to deliberately run software with known security flaws. Because it is possible to quickly deploy multiple VPS on a single computer, honeypots are much easier to deploy, allowing better insight into the world of computer security. VPS Hosting is a hosting environment that gives you your own Unix virtual machine. Each VPS is a private and protected area that operates as an independent server.

A growing technology in the web industry today is the VPS Hosting. VPS Hosting have combined strengths of dedicated servers and shared servers. In VPS Hosting the physical server at the root is divided into partitions. In fact VPS provides the features of a dedicated server to many customers as low cost. In case of VPS system resources like the CPU and RAM with other users.

VPS Hosting technology allows you to share server costs with other users. VPS run as isolated processes within a Web Server. VPS Hosting allows to spilt a server into smaller servers. A VPS Hosting is a simulation of hardware by a host operating system. Each VPS Hosting is isolated from the others. Every VPS Hosting program operates by accepting HTTP requests from the network, and VPS providing an HTTP response to the requester. Usually VPS have also the capability of some detailed information, about client requests and server responses, to log files; VPS Hosting allows the Web master to collect statistics by running log analyzers on log files.

VPS Hosting usually translate the path component of a Uniform Resource Locator (URL) into a local file system resource. The URL path specified by the client is relative to the VPS’s root directory. Each VPS can handle a limited number of concurrent client connections (usually between 2 and 60000) and VPS can serve only a certain maximum number of requests per second depending on VPS’s own settings, the HTTP request type and the hardware and software limits of the OS where VPS is working.

Using many VPS’s that are grouped together so that they act or are seen as one big VPS. Web hosting companies developed the VPS Hosting to provide features usually reserved for a dedicated server at a more affordable price. With a VPS, each web hosting account receives their own operating system.
