VPS hosting offers lower costs than dedicated server hosting (DNS and other services) because the VPS server is not accessed on a dedicated network connection. There are three main benefits to VPS hosting:

1. You have greater freedom to run your own software packages on the server.

2. You can use virtual private servers to host your public facing web sites or share your own servers with others.

3. VPS server provide a variety of hosting options including shared hosting, no contract, and/or high availability. Although they do have low access restrictions, most VPS’s have limited or no internet access, so you cannot download files from the internet.

For a variety of reasons, many organizations choose to buy or lease dedicated servers. They are the best solution for a small company or project, such as a team that wants dedicated servers for various use cases. High end dedicated server products are now common and cost about the same as private VPS servers. They may include hardware redundancy and even have a dedicated video and network card. But do note, that some dedicated servers offer more robust security services than VPS servers. So use them judiciously if you intend to host sensitive information on them, such as your bank or corporate password information, customer databases or financial information.

Having multiple VPS servers means you will need to get access to multiple servers. This may be easy to manage if you already have a dedicated server where you can manage each server using a common GUI. However, if you don’t have a dedicated server, you may have to make an account to view your VPS’s, configure them, and manage them. It is likely that you will also need to build your own password management software or use other security services such as WAPI, which offer free security assessment. An additional requirement is that all servers must have the same IP address. Sometimes you may need to enable the forwarding of your connections to different servers (most common if you are using external services) as we’ll explain in the next section.

As mentioned before, dedicated server hosts tend to offer higher access restrictions than VPS hosts. However, there are a few options. If you are using an existing dedicated server that does not have any user accounts, you should not be restricted at all. If you are running your own project or using a VPS for a personal use, you may have more access restrictions. We suggest that you ensure your VPS account is not already in the contact list of your company. We’re not discussing open VPS here; we’re talking about isolated VPS’s. For more information on account administration, please refer to section 3.3.

However, if you are interested in using dedicated servers for a project or if you are looking to purchase additional services, we suggest that you read our dedicated server guide. It explains how dedicated servers differ from VPS’s, how to register for a dedicated server, and what different level of services you can run on a dedicated server. We also explain why and how open or isolated VPS’s are an alternative. Having a separate guide for each level of service makes it easier to pick the right one for you.
