Core Benefits of VPS Hosting Over Shared Hosting

Benefits of VPS Web Hosting Over Shared Hosting

Usually, shared hosting is considered as an inexpensive solution, however with shared web hosting you will not get a full control over your website. If you want to have a complete control over your website and don’t want to lose your website performance by sharing resources, then you may go for VPS or dedicated server.

A Virtual Private Server (VPS) is one or more servers that run within another server, which makes you feel like a dedicated server as it share the same hardware, making it much advanced form of shared web hosting. To form a virtual private server numerous virtualization softwares like Virtuozzo & OpenVZ are used.

Let’s check out some core benefits of VPS hosting over Shared Hosting.

Like shared hosting, other virtual private servers running on same machine and hardware don’t get affected by CPU load and huge traffic. Hence, whatever your neighbors have going on, it won’t affect the performance of your personal hosting environment. Your VPS doesn’t have to share services or applications with its neighboring servers. As each server is independent and are completely invisible to neighbor, they too are not required to share processes or file system.

Generally, with shared hosting, if there are any errors and faults within the server it affects every website hosted on that server. But, if you encounter errors and faults within one virtual private server do not affect the others. In VPS each or your private server get a unique IP address so that it won’t affect sites hosted on other servers. Also, with root access, you will be able to install and manage many software applications on VPS hosting account same as you would on dedicated server.

Different from typical shared hosting, you don’t have to share your critical VPS resources such as CPU, bandwidth, diskspace and memory. Thus, you don’t have to quarrel for these significant elements, a VPS hosting package Since you don’t have to compete for these important elements, a VPS hosting solution tends to give you better uptime guarantee.

Regarding secutiry, a virtual private server ensures better security for the fact that you don’t have to share TCP/IP stacks, processes and disk space. The advanced security and better performance makes VPS web hosting an ideal solution for all sizes of businesses.

The core benefit of VPS hosting is that it offers you to run everything from custom made software and application to database servers and even your own operating system. Although, as compare to shared hosting, Vps hosting may seems to be a little bit expensive, but its far more affordable than going for a dedicated server.

Just think over the above advantages of VPS hosting and make your final decision.

OpenVZ Explained

OpenVZ

What is OpenVZ?

OpenVZ is server virtualization software provided by SWSoft, Inc. licensed under the GPL version 2. OpenVZ is the software that every system administrator requires. It allows you to host multiple Virtual Environments (Aka VE) on a single server. The only limitations are RAM and CPU.

OpenVZ is an operating system-level virtualization technology based on the Linux kernel and operating system. It allows a physical server to run multiple isolated operating system instances, known as Virtual Private Servers (VPS) or Virtual Environments (VE).

Unlike VMWare and Para virtualization technologies such as Xen, OpenVZ is more limited in that it requires both the host and guest OS to be Linux (although Linux distributions can be different in different VEs) under the same kernel. OpenVZ claims a true performance advantage. According to its website, there is only a 1-3% performance penalty for running OpenVZ compared to using a standalone server.

As OpenVZ employs a single kernel model, and is scalable as the 2.6 Linux kernels; in that it will support up to 64 CPUs and up to 64 GB of RAM. A single virtual environment can scale up to the whole physical box (known as a “heavy VPS”) i.e. use all the CPUs and the entire RAM.

OpenVZ is divided into a custom kernel and a number of user-level tools such as vzctl, vzstat etc. OpenVZ lacks some of the features of the commercial product Virtuozzo, such as the advanced vzfs file system, templating features, to save disk space, and additional user land tools and control panels (though third party ones have been written).

OpenVZ improves efficiency, flexibility and quality of service in the enterprise environment. Each Virtual Private Server is hardware independent and can be moved to another OpenVZ-based system in seconds over the network.

Some Important OpenVZ Commands:

  1. vzlist -a : Shows list of all the VPS’s hosted on the Node.
  2. vzctl start VPS_ID: To start the VPS.
  3. vzctl stop VPS_ID : To stop (Shut Down) the VPS
  4. vzctl status VPS_ID : To view the status of the particular VPS
  5. vzctl stop VPS_ID –fast : to stop the VPS quickly and forcefully
  6. vzctl enter VPS_ID : To enter in a particular VPS

Configuration Commands

  1. vzctl set VPS_ID –hostname vps.domain.com –save: To set the Hostname of a VPS.
  2. vzctl set VPS_ID –ipadd 1.2.3.4 –save : To add a new IP to the hosting VPS.
  3. vzctl set VPS_ID –ipdel 1.2.3.4 –save : To delete the IP from VPS.
  4. vzctl set VPS_ID –userpasswd root:new_password –save : to reset root password of a VPS.
  5. vzctl set VPS_ID –nameserver 1.2.3.4 –save : To add the nameserver IP’s to the VPS.
  6. vzctl exec VPS_ID command : To run any command on a VPS from Node.
  7. vzyum VPS_ID install package_name : To install any package/Software on a VPS from Node.

Here VPS_ID refers to the ID of the Particular VPS.
