I initially started using Digital Ocean when I was making the jump to managing my own VM’s. Before that I had been on shared hosting a lot or used systems like WAMP/XAMPP (the good ol’ days). Digital Ocean really got me into managing boxes and had a heap of tutorials that I read through. To this day whenever I search anything SysAdmin-ish I tag the word ‘Digital Ocean’ on the end hoping for a relevant tutorial on their site.
As for actually using Digital Ocean’s UI, there’s not much of a learning curve – they made a clean design that’s clear to follow. To fuel some of my other learning one weekend I will go through all their One-Click Apps and install things I’ve not used before so I can give it a go, things that interest me are Docker, ELK and Mongo DB.
