A VPS (Virtual Private Server) is a self contained server which exists on a larger, physical server. A portion of the physical server's resources (CPU, RAM, Disk space) are allocated to each VPS. They can run any OS (Operating System), have their own IP address(es) and are able to be individually customised. You can use a VPS to host websites or run software of your choice.
VPS hosting is more flexible, and a lot cheaper than running a full dedicated server. You’re able to increase or decrease in size as needed, meaning you don’t need to pay for resources you’re not using. A VPS also gives you significantly more control than with shared hosting, as you’re getting full access to the entire operating system.
In most cases, your VPS will be activated within a few minutes after the invoice is paid. In some rare cases (e.g. your order is flagged by our automated fraud prevention system), this may take slightly longer. If your VPS is not activated within a few hours, please open a support ticket with us.
CPU, Memory and Disk can all be upgraded. This happens on the fly for OpenVZ, whereas KVM requires a reboot. Note that if you're using KVM you will have to manually expand your disk partition, and it’s not possible to downgrade disk space.
We keep a wide range of operating system templates and ISOs (KVM only) available for use through our SolusVM control panel. Your VPS can be reinstalled with a new operating system on demand. If there’s a particular operating system, or a specific version that you need, please let us know by opening a ticket and we’ll do our best to provide it.
Once your server is activated, you’ll be provided with SSH login details for your server in your activation email. This will allow you to login as ‘root’ and will give you full access to the OS. To do this, you will need to enter your server’s IP address and login details in an SSH client (such as PuTTY on Windows). If you’re using KVM, you can also connect to your server using a VNC client. You can find the login details for VNC in the SolusVM control panel, which you can also use to manage your server.
KVM and OpenVZ are two different types of virtualization. KVM is considered ‘full’ virtualization, where each VPS has its own kernel. This allows KVM to have less restriction when it comes to functionality, but comes with greater overhead. OpenVZ uses the host node’s kernel instead, and is generally more affordable. OpenVZ also uses resources more efficiently, but can be limited in its choice of OS. See ‘Am I able to upgrade my VPS?’, ‘What Operating Systems can I choose?’ and ‘How do I access my VPS?’ for more details.
