Small SaaS, How much do you pay for hosting?

I have a small SaaS app running on a VPS at Linode. It's costing 8USD/Month:

  * $5/Month for a 1GB Ram Micro (Postgresql single instance, Rails)
  * $2/Month for Backups 
  * $1/Month for block storage (10GB)

That being said, I am planning a move to fly.io to get a replicated HA Postgress and my rails app. I expect it to run mostly on their free tier plus a bit for more than the things not covered on the free tier for a total of about $8.70/Month:

  * $3/Month for 2x10GB block storage (1 each for the postgres nodes)
  * $5.70/Month Shared CPU, 1 GB Ram VM (For the Rails app)

So a wash price wise. But fly.io will get me a better CI/CD/Deployment story, replicated HA Db, easy scale the db and app across geographic regions and a easy way to scale period.

Right now I'd need to build another box and get it hooked up, figure out a LB for it (or pay for Linodes), etc. I CAN automate some of that (Terraform, et al), but there's a learning curve and implementation effort cost. All stuff I am perfectly capable of doing but as a solo founder, I would rather spend time building value (features) and work on marketing & sales.

Hosted K8s at Linode or DO were options too, but still learning curve and the cost (to get started) would have been 5-10 times higher for the same thing (and I'm cheap :). Time will tell the cost curve as I scale, but it's a small app with a limited audience so it doesn't need much.

around $50 a month, app is made with nextjs, hosted on Google App engine with a postgres db.
