+Availability zone
+^^^^^^^^^^^^^^^^^
+
+The configuration of the availability zone is requred in cases where location
+of exact compute host/group of compute hosts needs to be specified for SampleVNF
+or traffic generator in the heat test case. If this is the case, please follow
+the instructions below.
+
+.. _`Create a host aggregate`:
+
+1. Create a host aggregate in the OpenStack and add the available compute hosts
+ into the aggregate group.
+
+ .. note:: Change the ``<AZ_NAME>`` (availability zone name), ``<AGG_NAME>``
+ (host aggregate name) and ``<HOST>`` (host name of one of the compute) in the
+ commands below.
+
+ .. code-block:: bash
+
+ # create host aggregate
+ openstack aggregate create --zone <AZ_NAME> --property availability_zone=<AZ_NAME> <AGG_NAME>
+ # show available hosts
+ openstack compute service list --service nova-compute
+ # add selected host into the host aggregate
+ openstack aggregate add host <AGG_NAME> <HOST>
+
+2. To specify the OpenStack location (the exact compute host or group of the hosts)
+ of SampleVNF or traffic generator in the heat test case, the ``availability_zone`` server
+ configuration option should be used. For example:
+
+ .. note:: The ``<AZ_NAME>`` (availability zone name) should be changed according
+ to the name used during the host aggregate creation steps above.
+
+ .. code-block:: yaml
+
+ context:
+ name: yardstick
+ image: yardstick-samplevnfs
+ ...
+ servers:
+ vnf__0:
+ ...
+ availability_zone: <AZ_NAME>
+ ...
+ tg__0:
+ ...
+ availability_zone: <AZ_NAME>
+ ...
+ networks:
+ ...
+
+There are two example of SampleVNF scale out test case which use the availability zone
+feature to specify the exact location of scaled VNFs and traffic generators.
+
+Those are:
+
+.. code-block:: console
+
+ <repo>/samples/vnf_samples/nsut/prox/tc_prox_heat_context_l2fwd_multiflow-2-scale-out.yaml
+ <repo>/samples/vnf_samples/nsut/vfw/tc_heat_rfc2544_ipv4_1rule_1flow_64B_trex_scale_out.yaml
+
+.. note:: This section describes the PROX scale-out testcase, but the same
+ procedure is used for the vFW test case.
+
+1. Before running the scale-out test case, make sure the host aggregates are
+ configured in the OpenStack environment. To check this, run the following
+ command:
+
+ .. code-block:: console
+
+ # show configured host aggregates (example)
+ openstack aggregate list
+ +----+------+-------------------+
+ | ID | Name | Availability Zone |
+ +----+------+-------------------+
+ | 4 | agg0 | AZ_NAME_0 |
+ | 5 | agg1 | AZ_NAME_1 |
+ +----+------+-------------------+
+
+2. If no host aggregates are configured, please use `steps above`__ to
+ configure them.
+
+__ `Create a host aggregate`_
+
+
+3. Run the SampleVNF PROX scale-out test case, specifying the availability
+ zone of each VNF and traffic generator as a task arguments.
+
+ .. note:: The ``az_0`` and ``az_1`` should be changed according to the host
+ aggregates created in the OpenStack.
+
+ .. code-block:: console
+
+ yardstick -d task start\
+ <repo>/samples/vnf_samples/nsut/prox/tc_prox_heat_context_l2fwd_multiflow-2-scale-out.yaml\
+ --task-args='{
+ "num_vnfs": 4, "availability_zone": {
+ "vnf_0": "az_0", "tg_0": "az_1",
+ "vnf_1": "az_0", "tg_1": "az_1",
+ "vnf_2": "az_0", "tg_2": "az_1",
+ "vnf_3": "az_0", "tg_3": "az_1"
+ }
+ }'
+
+ ``num_vnfs`` specifies how many VNFs are going to be deployed in the
+ ``heat`` contexts. ``vnf_X`` and ``tg_X`` arguments configure the
+ availability zone where the VNF and traffic generator is going to be deployed.
