waad to adfs (sso)

Objective: to have single sign on (o365, VSO, tableau, VPN, etc) using WAAD

Is WAAD greater or equal to ADFS ?

can I manage WAAD through a gui ? *or only through PowerShell?

can  WAAD talk with local AD?   (talk to, listen to, or both?)

 any help is appreciated

I just started a job, and the business wants SSO, and azure, o365, tableau, VSO, and other things to work seamlessly with Single Sign On.
