I'm slightly confused about Droplets
I'm a brand new customer to DigitalOcean, but I've had dedi and VPS servers since forever. I see that the way things work around DO are slightly different (particularly when it comes to droplets), so I'm slightly confused.
I've created a new Droplet with 1 GB of RAM, put Ubuntu 14.04 and installed Django on it. Simple enough, and it works. However, how do I install e.g. redmine on the same droplet? Do I just do it through the SSH ("the regular way")? I can't find an option to install another application on the same server. In other words, I would like to host multiple applications on the same droplet - is this possible?
Is there an idea to create a new droplet for every application you want to install? I assume not, since that would be just silly, but it seems that all tutorials are centered around that.
Am I charged per hour? In other words, if I destroy my droplet after 3 hours of use, will I be charged the full $10 a month, or just for those 3 hours?
