The physical Cisco ASA and Cisco ASAv support the same rich policy constructs. Virtual and physical domains are coalesced into a single policy domain so the same policies can be applied to all Cisco ASAs, whether they are physical or virtual.
Cisco ASAv offers the same features as a physical Cisco ASA, including VPN services that can be deployed in the virtual domain. Site-to-site, remote-access, and clientless VPN services can be deployed quickly in a private cloud or over a virtual infrastructure in response to demand.
Cisco ASAv offers the REST API, an HTTP-based interface that facilitates management of the appliance, including changing the security policy and monitoring the status. Using REST APIs, multiple cloud management solutions can be used to manage both physical and virtual instances of Cisco ASA.
