 * The left side of the diagram shows the virtual network and the VPN gateway that you create using the steps in this article.
 * You can later add different types of connections, as shown on the right side of the diagram. For example, you can create [Site-to-Site](tutorial-site-to-site-portal.md) and [Point-to-site](point-to-site-about.md) connections. See [VPN Gateway design](design.md) to view different design architectures that you can build.
