+Ingress Controller Installation
+-------------------------------
+
+In the production setup 2 different Ingress setups are supported.
+
+- Istio Gateway `Istio-Gateway`_ (currently tested, but in the future deprecated)
+- Gateway API `Gateway-API`_ (in Alpha status, but will be standard in the future)
+
+Depending on the solution, the ONAP helm values.yaml has to be configured.
+See the :ref:`OOM customized deployment<oom_customize_overrides>` section for more details.

+- create keycloak namespace
+
+  > kubectl create namespace keycloak
+  > kubectl label namespace keycloak istio-injection=enabled
+

+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- To configure the Postgres DB

+ONAP Deployment Options
+=======================
+
+OOM supports 2 different deployment options of ONAP.
+
+- Development Setup
+- Production Setup
+
+In the following sections describe the different setups.
+
+Development setup
+-----------------
+
+The development setup deploys ONAP components exposing its external services
+via NodePorts and without TLS termination and internal traffic encryption.
+
+Production setup
+----------------
+
+The production setup deploys ONAP components exposing its external services
+via Ingress with TLS termination.
+Internal traffic encryption will be ensured by using Istio ServiceMesh.
+
+.. figure:: ../../resources/images/servicemesh/ServiceMesh.png
+   :align: center
+
+For external access we start to establish Authentication via Oauth2-proxy
+and Keycloak which will be completed in the coming release.
