Networking: HA/Clustering for Amazon Cloud
The ability to operate a pair of UTM software appliances in a VPC, in different AWS availability zones, configured as HA/clustered pair.
This feature is critical in providing a truly HA VPC solution. I have the need to operate a very highly available VPN endpoint for multiple healthcare providers and this one deficient is preventing us from moving forward with the excellent UTM software appliances.
(Amazon has a white paper outlining how to make the default NAT instance highly available using two NAT instances and a script that detaches and reattaches the virtual interface and MAC to the standby instance.)

Emind system is an advanced AWS Partner, we deploy such HA topologies of NAT GW in the VPC.
