That's a huge instance with an enterprise license on top. Most large SaaS companies can run off of $5k / m or cheaper RDS deployments which isn't enough to pay someone. The amount of people running half a million a year RDS bills might not be that large. For most people RDS is worth it as soon as you have backup requirements and would have to implement them yourself.
> Most large SaaS companies can run off of $5k / m or cheaper RDS Hard disagree. An r6i.12xl Multi-AZ with 7500 IOPS / 500 GiB io1 books at $10K/month on its own. Add a read replica, even Single-AZ at a smaller size, and you’re half that again. And this is without the infra required to run a load balancer / connection pooler. I don’t know what your definition of “large” is, but the described would be adequate at best…
If you don't have a reserved instance, then you're giving up potentially a 50% discount on on-demand pricing.
An r6i.12xl is a huge instance.
There are other equivalents in the range of instances available (and you can change them as required, with downtime).
