Thanks! Very kind of you!

Well, I would like to include more, in fact I would include Ligthsail for sure if they offered a datacenter in Europe. But to start something like this you have to start small, or the costs will bury you pretty son. As a pet and personal project, the way to limit the cost was setting a clear seat of boundaries, like plans under $5 and available in Europe. And being one-man band to make this affordable in terms of time and effort I had to keep it small at the beginning. I worked on this in my spare time for more than two months. If I find a way to sustain the costs, or the providers itself offer me a way to test their machines, I have no problem to expand the comparison. But in the meantime, I share the tools because I knew from the beginning that I only have limited resources. And after all, reproducibility, independence and transparency are the keys IMHO to have a trustful comparison.

ec2 is different however lightsail would be comparable. sadly there is still no instance outside US.

Why is ec2 different?

you can combine different network adapters/storage options and instance types and also create your own virtual network, with various other options. while these VPS providers only allow a specific amount of storage for a specific type of instance and also have a included traffic option while ec2 does not have that. I mean more and more VPS providers have an API, but they still don't have the customizability and services like a cloud has, yet they are preferable in many use cases.

DO has block storage, Vultr has it on a couple regions and Linode seems to be preparing for that too.

How is what you described different than what DigitalOcean provides with droplet?
