What do people typically host on Raspberry Pi clusters? (alien.top)

I'm using a spare laptop (Lenovo E570) running Ubuntu as a remote Docker host, and I do personal web dev on it - I run things like Flask / Django web apps (which are basically small, single-user HTTP servers), MongoDB, Redis, sometimes MySQL. I'd like to add paperless-ngx to all that, but that's a problem for later for later.

How do Raspberry Pi clusters stack up against spare laptops in terms of Docker performance? If I were to build one out, how many would I need to match the performance of my old laptop, if at all possible? I know people run Kubernetes on these things, but is K8S really necessary? Or can I just use straight Docker (maybe Docker Swarm)? What kinds of things are RPI clusters suited for?

I have an email server so that I can send documents scanned from an older laser printer and be able to retrieve them. Setting an email server was the only way since drivers are no longer availble or windows based.

What ever website project I am working on. I tunnel from a VPS to my home network.

Git repo.

Your Lenovo will eat a Pi in performance, and in the ease of getting stuff done. For your use case of doing some testing and hosting of web apps, it's great.

The only reasons I can think of for moving to Pis would be because it's a cool thing to learn and play with - which is a totally valid reason in this community :-), but not what you've described.
