We did the same, self hosted to Rds was so much easier. I didn’t think it had a proxy though, and the new proxy is still just MySQL, so still needs pgbouncer?

Just for my curiosity; did you use EBS or instance storage?

Back when we did this instance storage was much faster than EBS but the difference was not as dramatic as it can be these days. For example:

i3.2xlarge -> 180,000 write IOPS (4KB) 456$/month EBS 16TiB volume -> 16,000 IOPS (16KB) (more than 1,500$/month)

The difference in price and performance (NVMe can go much higher than this) could justify the EC2 self-hosted approach.

This was a while ago, maybe even before i families, but our boss refused to use ebs at the time because of the ebs failure a couple years before that. What changed his mind was a instance termination that took way to long to recover from, and there been a ton of ebs improvement since then

You are right. I am quite sure they will add support for PG as well but at the moment proxies are only for MySQL.
