Inter-site connectivity with VPN service

As business grows, it might be necessary to expand the cloud environment to multiple data centers. Of course, the implementation of a VPN setup whether it is a simple SSL one or an IPSEC solution will provide a secure communication path for the tenant traffic across the Internet. OpenStack provides isolated networks and network access control to avoid traffic congestion and improve the security of the internal network of the OpenStack environment. The VPN as a Service (VPNaaS) function protects the integrity of data by using the tunneling and encryption to provide a secure connection between machines that are geographically located in different data centers.

Add an admin user to each project in the admin role. This will allow you to fully perform administrative tasks in horizon. Additionally, you can create different users per project and assign a service type to it using an admin account.
