Ask HN: How to scale 1 server : 1 customer model?

1 point

Hi guys I need some help figuring out this pattern. I have a web application currently running on flask at site.com for each of my customer, I want to have a droplet from digitalocean running the copy of the flask app.

I want to consolidate them under a subdomain like customername.site.com

so when they go to customername.site.com, the ip points to their own server.

Now the problem I have is handling cases like: user logs in at site.com, needs to be logged in at customername.site.com user logs out at customername.site.com, needs to be logged out at site.com how do you configure an encrypted password for a new droplet instance? how do you update all droplets with updated code?

The reason I have one user per one droplet is because they run cpu and network intensive background jobs in parallel. I don't want them to interfere with each other.

I guess I'm trying to achieve horizontal scalability, by just cloning an instance of my original web application, instead of trying to force everyone on the same instance. Any suggestions or feedback would be very useful.
