This is a low cost option for the hosting company and they will usually offer some kind of data protection using a RAID system where data is copied across multiple disks. This is an entry level solution but one issue is that the server itself represents a single point of failure. It could be that the power supply fails which brings the server down for example.

A virtual private server (VPS), also called a virtual dedicated server (VDS), 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.

The golden rule for unmanaged VPS hosting is this: If you have a problem with your unmanaged VPS Account, it is your problem. If the problem is software related, resource related, performance related, need troubleshooting or configuration of software, or need general help understanding Unix or server applications, you are on your own and should not expect help from the web host.

We combine blazing fast hardware with KVM virtualization, giving you full isolation from your neighbors and complete flexibility to run any OS, kernel, and software you want.
Virtual private servers have become a popular choice for web hosting because they offer many benefits of dedicated servers at a lower cost. They also provide the added benefit of easy scalability. Since each VPS is virtualized, the configuration can be updated with a software modification rather than a hardware upgrade. Still, dedicated servers often provide better performance since all the resources of the physical machine are dedicated to a single server.
In a dedicated hosting plan, a client leases or rents a physical server from a hosting provider. With Dedicated hosting plans, the client has complete control of the physical server and access to all its resources. This is a good fit for companies that have websites that expect a high amount of traffic, that are running intensive CPU applications, and that are hosting enterprise CMS sites.
With a VPS, you receive all the power of Dedicated Server Hosting plus the ability to maintain your own set of services and customizable disk space. Here, you can also perform any desired actions from your control panel, without the need to contact our technical support team. With Shared Hosting, however, you have limited administrative access and are not able to customize software configurations. Learn more about the differences →

If you host it in a VPS environment, your site won't share resources with neighboring sites, the way it would with shared hosting. In fact, your site lives in a partitioned server area that has its own operating system, storage, RAM, and monthly data transfer limits, so you can expect smoother, more stable site performance. The sites with which you share your server are far less likely to affect your site—or even take it down altogether—than they would be on a shared site. Knowing how VPS setups operate is just the first step, however. You still need to familiarize yourself with the essential features needed for building a rock-solid, VPS-hosted website.
The concept of a virtual private server can be better explained as a virtual machine that caters to the individual needs of a user just as a separate physical computer that is dedicated to a particular user. The virtual dedicated server provides the same functionality and privacy as that of a normal physical computer. A number of virtual private servers can be installed on a single physical server with each one running its own operating system.

You can easily customize the network configuration for your Amazon VPC. For example, you can create a public-facing subnet for your web servers that has access to the Internet, and place your backend systems such as databases or application servers in a private-facing subnet with no Internet access. You can leverage multiple layers of security, including security groups and network access control lists, to help control access to Amazon EC2 instances in each subnet.
