Hi @Mahmoud-Osama ,

 

Choosing type of HA mode (Active-Passive or Active-Active) depends on the different use cases and requirements. Active-Passive is comparatively simple design.

 

One of the preferred reasons to use Active-Active setup is when you have Asymmetric Routing. Having said that, there are few other use cases of having A-A setup like when you need to load balance traffic on both instances in real time.

Active-Passive mode is mostly preferred one unless you have some specific use cases as given above which can be fulfilled using Active-Active setup only.

 

Article shared by @kiwi will give you more understanding about the HA modes.

 

Hope it helps!

thanks for your reply, what i am understanding is as per the article, the active-active mode is not  "Load-balance traffic".

 

Active/Active mode has faster failover and can handle peak traffic flows better than Active/Passive mode because both firewalls are actively processing traffic.

 

So, I need to understand what is best for me, Active-Active or Active-Passive
