We are planning to install two ASAv with HA (Active/Standby mode) to achieve redundancy in two different Availability zones in our AWS public cloud.
We understand that AWS blocks layer-2 visibility required for native HA and VPN load balancing. To enable resiliency and VPN load balancing, one must rely on the native cloud services such as AWS Route 53 and AWS route table.
However how can we achive redundancy (Automatic Failover)/ HA in Active/Standby mode ? Is there an official solution available to this need using AWS functions? Can you share the link of the documention avaialble if any?
