Edge Cloud Infrastructure Hardware Profile Requirements
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In the case of Telco Edge Cloud Deployments, hardware requirements can differ from the above to account for
environmental and other constraints.
The Reference Model :ref:`ref_model/chapters/chapter08:chapter 8 Hybrid Multi-Cloud: Data Centre to Edge`
includes considerations specific to deployments at the edge of the network. The infrastructure profiles "Basic" and
"High Performance" as per :ref:`ref_model/chapters/chapter04:profiles and workload flavours` still apply, but a number
of requirements of the above table are relaxed as follows:
