A virtual host on Edge defines the domains and ports on which an API proxy is exposed, and, by extension, the URL that apps use to access an API proxy.
A virtual host also defines whether the API proxy is accessed by using the HTTP protocol, or by the encrypted HTTPS protocol that uses TLS. When configuring a virtual host to use HTTPS and TLS, you configure the virtual host to use a keystore and/or a truststore.
Because Cloud customers can only create virtual hosts that support TLS, see Configuring virtual hosts for the Cloud for instructions on creating a virtual host.
