Vanity URL - EPM CLoud

Hi All

Using Vanity URL is nice feature launched by Oracle recently, however, how to build Vanity URL without using a third party tool (like REBRANDLY) for EPM Cloud?

My concerns - The third party tool will require a cost, always the service needs to be up, potentially we are routing all traffic then from EPM (initially through this new third party website)?

Has any one implemented Vanity URL? any challenges they faced?

thank you in advance!
