 ### Common Option with High Availabikity
 
-The common firewall option wiht High Availability leverages a single set of VM-Series firewalls that acts as a single entity. The sole set of firewalls operates as a shared resource and may present scale limitations with all traffic flowing through a single set of firewalls due to the performance degradation that occurs when traffic crosses virtual routers. This option is suitable for proof-of-concepts and smaller scale deployments because the number of firewalls is low. However, the technical integration complexity is high.
