7. © 2016 ADVA Optical Networking. All rights reserved.7 Typical Cloud-Based Service • The path through the data center is not assured! (No guardrails) • The data center and connectivity are owned by different SPs Even if you wanted to do HW assurance in the DC, where would you place an EAD? Enterprise Data Center Per-server VMs, vSwitch and hypervisor
