A company wants to integrate public cloud offerings to address its growing business units. The company uses many different applications from partners, and account access management hinders user…

Federation services enable single sign-on (SSO), allowing users to access multiple disparate applications, including those from partners, with a single set of credentials, thus streamlining account access management and improving user experience. This centralizes identity management and trusts across different security domains.

Automation services focus on streamlining repetitive tasks and workflows, not specifically on centralizing user access management across different partner applications.

Provisioning services deal with creating, updating, and deleting user accounts or resources, but do not inherently provide a centralized single sign-on experience across multiple, distinct partner applications.

Orchestration services manage the coordination and workflow of complex deployments and operational tasks across multiple systems, which is unrelated to simplifying user identity and access across partner applications.
