I've been wondering this for a while -- why are people using DBaaS? Wouldn't you use an AMI of choice, self-host, or use one of the cloud native solutions? Seems like piping all your DB calls outside your VPC would have a lot of downsides, not the least of which is a lot of latency (I get there is peering infrastructure). Also, there are security issues to contend with, threat surface is much larger with a DB available to the internet vs a DB on a segmented private network only available to the middle tier. Is it a cost thing? Is something like xata or neon cheaper than say AWS Aurora? I don't see how it could be cheaper with all the inherent egress costs.
