I am looking for a Azure solution architect to provide me for a detailed architecture design document for a SAAS solution. In essence, the SAAS solution for the client will be hosted on my Azure cloud instance. Selected users from the client will login and will authenticate via the client Azure AD. External users that support the client will also have the ability to login using login credentials provided by the client. Security is a major concern for the client so the architecture must incorporate this in the design principles. Security will be handled in the app using role based access control. Refer to attached Level 1 architecture.
