4.2 vCloud Availability Portal
The vCloud Availability for vCloud Director portal is a virtual appliance that provides a graphical user interface for tenants to manage their replications when they have no access to their on-premises vSphere Web Client user interface. The portal provides web UI on TCP port 8443 and requires a vCloud API connection.

The appliance is stateless, and with a network load balancer supporting sticky sessions, it can be deployed in highly available and horizontally scalable configuration. Additionally, it can be scaled up vertically in three different virtual hardware configurations depending on the number of concurrent sessions each appliance must serve.
