We have three web servers where we want both balancing of the incoming traffic as well as redundancy of availability zones.
Are regional zones used for both HA and redundancy?
Should we use a cross zone scale set or should we use a LB?
Does it make sense to use two servers in a cross zone scale set?
If we have a system composed of a SQL AG which requires a internal LB and a application server does it make sense to availability zones if the connection between application server and SQL AG's must have a very low latency?
What do you recommend if we are wanting to keep both the SQL AG and Application in the same regional zone however you also want resiliency from a database location (regional zone) going offline (ie flooding)?
