What Resources Do You Recommended To Run cPanel?

It is recommended to select a VPS with at least 40 GB of disk space, 2 GB of RAM and 1 CPU core when you choose to purchase a VPS with a cPanel license from Hostwinds. During the order process, you can choose to add a cPanel license by checking the box. Adding more resources for email, website files and optimal performance may vary depending on your needs and having more resources will increase the speed and overall performance of your VPS.

cPanel is only compatible with CentOS and you can review and purchase the license from Hostwinds here.  Furthermore, upon request in a ticket, our technical support will assist with any installation needs as long as the service is managed and not unmanaged.

Which VPS Is Right For Me? 

The answer to this question can depend on how you plan to use your VPS. It is important to ask yourself these questions:

How many accounts and websites will be using this server? 

The higher the number of websites that will be on your server, the more resources you will need. It is easy to upgrade as your account grows and needs more resources if you notice that you will need to have additional resources.

What will you be using this server for? 

The minimum requirements that we offer with our tier 3 VPS will be able to run cPanel/WHM. For websites that need more resources for high amounts of traffic, heavy resource usage for their applications, hosting videos and music, this will require more resources and a higher tier VPS is recommended.
