I'm curious on the decision from our two engineers to handle the database on their own for many of the initial phases instead of offloading to a fully managed database service in AWS (DDB or RDS depending on needs).
What could be the reasons they decided to host them in EC2 instances? Costs? A particular DB technology not offered as a service in AWS?
The cost difference can be significant, with self-hosting on EC2 potentially saving 40-60% compared to RDS, depending on the instance type and workload. However, it requires more management effort:
