Where to host a second site.
ADDON DOMAIN
Same account, shared resources, one login, one bill.
Cheaper and simpler.
SEPARATE ACCOUNT
Its own resources, its own backups, complete separation.
WHEN AN ADDON IS FINE
Your own second site A small project Something with modest traffic
WHEN A SEPARATE ACCOUNT IS BETTER
A client site Anything where a compromise must not reach the others A site with substantially different requirements Anything you may sell or hand over
THAT LAST POINT
Separating a site from a shared account later is work.
If you may hand it over, start it separately.
THE SECURITY POINT
On shared hosting, sites in one account share a filesystem.
A compromise of one can reach the others.
FOR RESELLERS
Separate cPanel accounts per client, through a reseller plan.
That is what reseller hosting is for.
