I am developing a authentication service that authenticate the client service based on the credential and after authentication, client service would be eligble to access restful api to put and get data. Please guide me which cloud service i can use for above scenario and i have following limitation while chosing authentication method.
As per the above scenario, Client service would access the restful api so i can not maintain client session in restful api so i can not use any token authentication method.
I need to achive cloud agnostic so same authentication service should available in Google, Amazon and Azure.
