The blog of OpsDash, a self-hosted server and service monitoring product, with technical posts on Postgres, Go, and Linux tools.
Commenters sometimes mention OpsDash as a monitoring option, and one says its blog has interesting technical posts, especially on Postgres and Go.
I don't think you're being fair with your comparisons to DO when it comes to price. The f1 micro $5/month Google servers are SO much worse.
Those "always free" f1 micros have 600mb of RAM, do not have SSDs and according to some tests[0] you only get 20% of 1 vCPU. There's also some pretty severe write limitations.
That's a really big difference vs DO's 1gb of RAM, SSD and 100% of 1 vCPU. The performance difference alone with SSD vs no-SSD is massive, especially on a database and while most web apps aren't CPU bound, 20% of 1 vCPU is bound to run into problems beyond a simple hello world that you set up in your example.
Also what happens if your app doesn't even fit in that 600mb? On DO you could get a 600mb app + 100mb OS + 150mb DB + whatever else running on that $5/month server since it has 1gb of ram.
In a real world application I wouldn't be surprised if that cluster performs way worse than a single DO server in the $5/month range. In some cases your app wouldn't even be able to run.

> PostgreSQL uses the term cluster to refer to a “cluster” of databases, as opposed to the usual notion of a group of servers or VMs working in a co-ordinated fashion.

Note that the "databases" above are logical databases, not database hosts.
Would be interested if it could do something like OpsDash[1]. Also, would it work with a AWS RDS Postgres?

I like how they display uptime. Does another service do this? http://www.opsdash.com/images/sources.png
