I need help redesigning the services I use on Digital Ocean

Hello,

I am a long-time Digital Ocean customer. My only goal is to serve different websites, built with different technologies (either php, node, python, etc depending on the project).

When I created my first droplet, it made sense to me to just run a single linux VM with a LAMP stack, but managing this setup is now limiting my work, especially because I am not a system/network engineer, and year after year everything in becoming less stable.

I have been able to upgrade everything to Ubuntu 22.04, and decided to move all the mysql data to a DO managed DB. Next step would be to move all the localhosts that are now running on the VM to a Dokku od Docker droplet as single apps.

But I also have apps that upload, save and serve static content, such as images or small files.

That said:

1. Are DO spaces a good fit to serve this kind of static content? Or is there any other DO product that better fits this goal?
2. I have a very rough sketch of what I was thinking to obtain, can be seen here: https://imgur.com/a/begqmDq Anyone who actually knows about this kind of things can please tell me if this looks crazy or might work? The amount of traffic generated is scarce, because I am just publishing personal projects with a very limited audience (the goal is to build and maintain portfolio since all the work I do is generally protected by very strict NDAs)

Thank you in advance to anyone who will answer :) Simone
