There are few reasons we haven't done this yet:
1) cost (minimal) 2) Public IPv4 addresses are limited per VPC / region. We could apply for a quote increase, but eventually we'd likely run out.
In most cases the reason for a public IP is to add these to an allow list when FusionAuth sends events to a webhook. Perhaps there are other use cases as well.
For this specific use case, one option would be to use an internet gateway per VPC and then route all egress through a gateway with a few static IPs that we can document for this purpose. This may work - and may be the preferred solution.
I don't think elastic ips can be assigned to load balancers.
I am thinking more of a proxy config to route all egress out of the VPC on one or more static IPs. I would guess it is possible with one of these options:

An implementation of this work is currently in progress.
Add ability to have static ip for FusionAuth cloud instances
Heard this from one customer.
Problem
I want to use FusionAuth cloud but need to have a hole punched in my firewall. I want to have a static IP I can ask the network engineers to add to the firewall allowlist.
Solution
Have a static IP address for my FusionAuth cloud instance.
Alternatives/workarounds
Self host FusionAuth, I guess.
