I am looking for a machine to run distributed computing projects. New to cloud computing - but I like the sound of it.
But, I haven’t seen what I am buying. What does it look like? Like my comp has an i7-blah blah. But what would my virtual workstation look like? I may start with a single Xeon core and some RAM which I may want to upgrade further.
So summary:
- What am I buying/renting?
- Do I have to install Windows/Linux on it?
- Would I see a About page with how many processors and RAM I have?
- Can I upgrade in say 3 days?

- You’re renting a Cloud VPS/Droplet, you can pay hourly or monthly.
- On the setup droplet page you can install a linux distribution.
- Yes on the control panel, though you can install linux dash if you want to see exact specs.
- Yes, you can resize your droplet whenever you feel like it.
Here’s the specs that I get from different commands on a $40.00 system:
