VPS vs Shared Hosting

Why most of the users prefer VPS and Not Shared Hosting….

VPS provides some interesting feature which are also available with Dedicated servers.

* Full Root Access & ability to install customized script.
* Define the server environment for customer.
* Isolated and protected from other domain on the server which may be abusing the server or overusing server resources.
* Dedicated mail, MySQL, FTP, http server.
* Dedicated Outgoing MailServer IP.

We can consider SHARED HOSTING is like living in an apartment building and sharing your neighbours’ problems. You hear their music through the wall. If one of them leaves the main door open, your security is at risk.

On a shared server, all the website hostings share the operating system and resources. Problems with your neighbours’ website hostings can slow down the server performance or require it to be shut down while the problem is being fixed. The slowdowns may also resulted from having too many website hostings on a server. Your site’s security depends in part on decisions made by your web host and, perhaps, your neighbours too.

Depending on your neighbours and, to a larger extent, your web host, you may have few or no problems with a shared hosting account. By sharing the resources, the cost is more economical than a VPS Hosting. Furthermore, for a basic website hosting, you require little or no technical knowledge to maintain your website hosting.

The majority of website hostings are on shared servers.

Where VPS Hosting HOSTING is more like living in a townhouse with your own private yard, and without ever hearing your neighbours. The only common area you share is the parking area and entrance; all traffic goes through one network port. In contrast to apartments or shared hosting accounts, you pay more for a VPS Hosting, but you can do what you want with the space, and your neighbors’ problems aren’t your problems.

VPS Hosting gives you the features and functionality of a dedicated server without the cost of building and maintaining one. If you need to host unlimited domains, have complete control of your environment and run your own applications, then you will benefit from having a VPS Hosting. In addition, a VPS Hosting provides the ability to manage your dedicated environment directly through SSH or Remote Desktop Connection. In addition, you can add a control panel like cPanel to our Linux VPS Hosting Plus plan. The control panel enables the administrative user to perform actions to their VPS Hosting immediately, without having to contact support to have a technician to complete any necessary requests.

What is VPS ?

Written by Jahangir on September 17, 2008 – 1:39 am -

A Virtual Private Server or Virtual Dedicated Server (VPS or VDS) is a method of partitioning a physical server into multiple servers such that each VPS has the appearance and capabilities of running on its own dedicated machine. Each virtual server account have its own operating system, can rebooted independently and have root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files. It fills the gap between shared hosting and dedicated hosting.

There are two kinds of virtualizations: software based and hardware based.
In a software based virtualization environment, the virtual machines share the same kernel and actually require the main node’s resources. This kind of virtualization normally has many benefits in a web hosting environment because of quota incrementing and decrementing in real time with no need to restart the node. The main examples are Virtuozzo, HyperVM, OpenVZ and Xen which is the core kernel of both Virtuozzo and HyperVM.

In a hardware based virtualization, the virtualization mechanism partitions the real hardware resources. In typical implementations, no burst or realtime quota modification is possible; the limits are hard and can only be modified by restarting a virtual machine instance. This kind of environment is potentially more secure in the sense that it is less subject to “Quality of Service crosstalk” between VM instances; on the other hand, its security is typically dependent on the correctness of a larger and more complicated Trusted Computing Base. It is more commonly used in big originations or commercial deployments. Examples include VMware ESX Server, Microsoft Virtual Server and Xen.

Virtual Private Server Hosting

A growing number of companies offer Virtual Private Server Hosting or Virtual Dedicated Server Hosting as an extension for Web hosting services. Some web hosting companies call a Virtual Private Server [VPS], Virtual Dedicated Server [VDS] or Virtual Dynamic Dedicated Server.

These types of hosting accounts are usually used as a stepping stone between your basic shared hosting accounts and dedicated hosting accounts. VPS server provides the flexibility of a dedicated server, users shares the system resources, such as the CPU and memory but unlike shared hosting (a virtual host on a shared hardware server) the file system is fully partitioned. Which provides more up-time and more consistenticy, also root access to the server provides the flexibility to add and change modules and to install your own software’s. You get all of the benefits of having your own dedicated machine, but you still have some limitation as to what you can do with it.

VPS is a much needed plan in between your shared and dedicated hosting. It allows you a little more flexibility than a shared hosting account, but limits you more than a dedicated account.
