I am made a Pern stack app for a school which can perform crud operations. The database is Postgres and it will have 10 tables and approximately 2000 rows for each table. How much will hosting this app cost monthly?

Hi there,
Yes, this tech stack could be set up on a single $5/mo Droplet. However the size of the server would depend on the complexity of the app, the amount of traffic and the resources that the app needs.
What I usually suggest is:

That way you will be able to tell how much traffic your app can handle with the resources that you’ve selected.
If you see any bottlenecks like CPU or RAM, then you could upgrade the Droplet accordingly. This way you would know how much traffic you can handle and be ready for production.
In case that you need this, there are a lot of resources on the DigitalOcean community site that would help you with the installation and configuration of the Droplet. For example:
Here is how to install Postgres: https://www.digitalocean.com/community/tutorials/how-to-install-and-use-postgresql-on-ubuntu-20-04?comment=103340
Alternatively you could use the Managed Postgres Clusters rather than installing Postgres on the same server as your web services:

Hope that this helps. Best, Bobby
