Architecture for Unified Communications diagram

Users on a corporate network register UC applications and devices by using Direct Connect or AWS Site-to-Site VPN.
Remote workers connect UC applications and devices through the public internet.
UC devices and soft clients pull configuration from Avaya Aura Device Services (AADS) that runs on Amazon Elastic Compute Cloud (Amazon EC2).
Sessions are established with one of the Session Border Controllers (SBCs) as entry points managed by the Element Management System (EMS).
User authentication and session management occur at the Session Managers, controlled by the System Manager.
Communication Manager provides telephony features with Media Servers for digital signal processing (DSP) resources.
Amazon WorkSpaces provides a simplified bastion host for management activities.
Directory Service provides a unified directory for user creation.
Avaya Aura roles are distributed in two Availability Zones for high availability (HA) purposes.
