VPS hosting is a service that provides short-term or long-term virtual servers (sometimes called "virtual private servers" or VPS) to customers on demand, also known as cloud computing. A customer can have full control over the server and its configuration, allowing companies to serve more customers without making physical upgrades to their hardware. For example, a VPS can be made available so that the company's web server or file server can be located within the customer's server room.
VPS hosting can also be an economical solution for creating virtual private network (VPN) connections between two customers to create a secure link between two offices. VPS hosting charges are billed per hour, but there is no need to buy hardware. All that is needed is a basic router, computer, or device with Internet access and enough horsepower to run software packages like DynDNS or BlueCoat (and possibly IP addresses).
How Does VPS Hosting Work?
When customers choose a new service, they should select the appropriate plan based on their needs and the services currently offered. The basic level of service is called "shared hosting" because the customer shares the resources of the company's Internet server. This means that every customer can access all resources on this server at identical speeds and that having many customers connected to one server will not result in slower speeds for any user. By comparison, VPS servers are just like individual servers dedicated to a particular customer on a different physical computer but sharing resources with other customers as needed. This allows for greater performance since the help of a single physical computer can be better utilized. For example, a customer that requires more disk space will have faster performance since there are twice as many disk drives in the system as in a shared hosting environment.
The level of service determines how much traffic can be sent to the server. With shared hosting, customers can ship anywhere from 1 TB of monthly traffic to unlimited traffic. As traffic increases (especially if the company has many customers connected to their VPS), this traffic can become difficult to handle. In these situations, administrators may need additional bandwidth for their network. Companies may upgrade their VPS hosting plan by adding a dedicated IP address or higher speeds on their Internet connection to solve this issue.
VPS hosting offers more disk space by default because low-end plans provide at least 10 GB of disk space, whereas shared hosting plans may only submit 5 GB. While the standard with shared hosting plans is to allow customers to upgrade their disk space if their business needs require it, customers that use VPS servers can increase their storage whenever they want. This has many advantages for businesses. For example, computers and applications with large amounts of data may slow down because the server runs out of memory or space to store data, so administrators can easily increase the amount of storage available to reduce expensive hardware upgrades when larger servers are needed.
VPS hosting services may offer coupons and other discounts by separating the price of the service from the cost of its hardware (the hard drive and other components that make up servers). This saves some customers money on their VPS server compared to a second server but provides more disk space, memory, and faster speeds.
Some customers may require specialized hardware (such as a separate processor or higher-speed Internet access) that is unavailable under a standard VPS plan. For example, suppose a customer needs to run some database software exclusively on their server instead of using it for normal web pages. In that case, this is an excellent reason to upgrade their service.
What are the benefits of VPS hosting?
- Increases security. Customers do not want their files compromised when they share resources of a shared hosting server with many other customers because if this happens to one customer, it will happen to each of them.
- Offers faster performance. Even if the business needs more disk space (for example) and there are more than 1,000 customers online at once, each one will be able to access it with equal performance because the resource requirements are parceled out among all the users equally.
- Offers better redundancy. With a VPS server, if one customer's Internet connection goes down due to power surges or other problems, the other customers will also lose their connection.
- Offers higher security. A dedicated IP address allows administrators to keep all customers' data stored separately on separate physical computers instead of using the same shared server for all customers' data. This means that if hackers break into one customer's computer, they cannot steal that customer's data if it happens to be stored on the same physical computer as another customer's.
What are the disadvantages of VPS hosting?
Customer upgrades may cost too much money or not work at all. When customers need increased disk space or higher speeds, they may find that they are limited in their options, and the only option may be purchasing a new VPS server (sometimes called shared hosting).
Customer upgrades require someone with technical expertise. Customers need to know how to install software or make changes to their VPS server to take advantage of the higher speeds and other improvements.
Hardware failures have become more common. This means that customers need a backup server and offsite backup services to restore their data if there is a hardware failure.
Fewer levels of service are available than with shared hosting plans.
When should you upgrade to a VPS hosting plan?
Customers should consider upgrading to a VPS hosting plan as soon as their needs exceed shared hosting limits or another web hosting plan. However, customers who need to upgrade may find that they are paying for features they do not want or need but are forced to pay for them to get the features that make a VPS hosting plan worth their money.
If you don't know what you're doing, you may find yourself with a VPS server with more speed and disk space than you need, so it is better if you go into your transaction with an understanding of your needs.
