What is Virtual Private Server – VPS ?
Different types of web hosting allow you to perform different levels of customization on your server. They vary in pricing, performance and the availability of the service (e.g. uptime) as well.
Before Knowing about VPS, lets know little about different types of hosting servers.
In shared hosting, you split the same physical server with a number of other clients of the hosting company. You don’t get dedicated resources allocated to you, as your site runs on the same operating system as everyone else’s.
Shared hosting is the solution for website owners with lower traffic sites. It is the starting point of most small businesses and bloggers.
In dedicated hosting, you rent an entire physical server for your business. If you have a high-traffic website, dedicated hosting can be the best solution for you, as dedicated servers are fast, flexible, and fully customizable.
While Virtual Private Server (VPS) is mid way between these two. A virtual private server, also sometime called a virtual dedicated server (VDS) (but not the same), is a virtual server that appears to the user as a dedicated server, but that is actually installed on a computer serving multiple websites. A single computer can have several VPSs, each one with its own operating system (OS) that runs the hosting software for a particular user.
Using virtualization technology, your hosting provider installs a virtual layer on top of the operating system (OS) of the server. This layer divides the server into partitions and allows each user to install their own OS and software.Therefore, a virtual private server (VPS) is both virtual and private because you have complete control.
Running a VPS lets you set up your website within a secure container with guaranteed resources (memory, disk space, CPU cores, etc.) you don’t have to share with other users.
One of the primary advantages to using a VPS, as opposed to a traditional web hosting service, is that the subscriber has full access to the VPS’s OS, with unrestricted root or administrator permissions.
Advantages and Disadvantages of using VPS
- Dedicated resources that ensure your website won’t suffer the consequences if a website on a shared hosting plan starts consuming a large amount of resources.
- Customization options allow you to customize your OS and other aspects of your server such as server applications (e.g. Apache, PHP, MySQL, etc).
- Control/security gives you more flexibility in respects to powering down or restarting the server. A VPS also allows you to use SSH access and there is less chance of compromised privacy.
- Some technical ability is required to set up a VPS. This can include installing server applications, configuring user access, etc.
- Priced higher than shared hosting. Although the VPS option is priced higher than shared hosting, it does provide you with additional features and benefits.
FAQ about VPS and VDS
What is difference between VPS and VDS?
The difference between a VPS and VDS is simple. A VDS instance takes up the entire server and the whole server space is yours. whereas a VPS is a server configured to host multiple server instances, but it appears to be like the entire server is yours. That’s why it is termed as virtual private. The VDS configuration essentially gives you the dedicated resources of a server, however, the virtualized layer sits on top of the server itself.
In VPS, you are provided with part of the big machine, but with limited options. You can store on your server an unlimited number of databases running on MySQL, mail, FTP, as well as to deploy a large number of web-pages, to install any software.
VDS only differs that the software is installed first to create a virtual machine, such as Xen, and only then the OS. Since Xen is running in virtual mode, it can be assumed that the VDS is still better VPS, but still there is no noticeable difference between the two.
What is a VPS server used for?
VPS hosting is a type of hosting suited for people who have outgrown shared hosting. In normal hosting where multiple sites reside on a single web server with shared hosting, and have no guarantee of resources, VPS allows fewer users to share allocated segments of hard drive space, memory, and processor power.
