What is the differences between CNAME and Alias in Scaleflex (Cloudimage & Filerobot)


CNAME means Canonical name. This record is used to define multiple domain names for a single system.

If several services are running on a single system and every service needs its domain, the CNAME record is used.
For example, if a web server and FTP server are running on the same system, CNAMEs must be created for both of them.

System name - system1.abc.com 
Web server - www.abc.com 
FTP server - ftp.system1.com

The most common use of the CNAME is to provide access to a single web server using the standard "www.domain.com" and "domain.com" (with and without "www"). When renaming a domain, this setup can also redirect the old name of the web server to the new one.

To avoid circular references, the CNAME should always point to an actual hostname and never another CNAME.

In Cloudimage, to add CNAMEs you should contact our support team.



The Alias in the Scaleflex system is used to shorten the URLs.

For example, if an alias _sample_ is set to http://sample.li, the URLs will look like:

without Alias - //doc.cloudimg.io/v7/http://sample.li/boat.jpg?width=800 
with Alias - //doc.cloudimg.io/v7/_sample_/boat.jpg?width=800

In Cloudimage, you can add Aliases from the Admin panel -> Image Settings -> Domains tab:
