+Understanding architecture
+==========================
+
+Harbor imposes the architecture of a centralized gateway for web services. It is just like in a cloud, or in Kubernetes -
+the centralized Ingress/Webserver takes the traffic and routes it to other services.
+
+.. image:: ../harbor-architecture.png
+
+**Advantages:**
+
+- Easy to manage, and to maintain, one router to reload
+- Integration with services such as LetsEncrypt without additional work to be done
+- Most popular architecture for hosting multiple services
+- SSL termination at the router edge makes SSL support almost transparent to applications
