How many domains can I host on a Cloud Server

The number of domains you can use on a Cloud Server is determined by many factors such as:
1. CPU and Ram
2. How active the sites are
3.Number of sites on the server

Having more CPU and Ram is best, up to a certain point.

If the site is active we would recommend using CloudFlare's CDN (Content Delivery Network). This will reduce resources on your Cloud Server.

The more sites you put on a Cloud Server, the busier it can be. For any serious site, we suggest starting at least at the Windows 2 level. If you will be developing on the Cloud Server for an extended time before you go live, then start with the Windows 1 if you want; just remember the Windows 2 or Windows 3 will offer better performance.
