I bought my first DigitalOcean VPS for $5/month in high school. The same one is still running today, around 4 years later. One of the best investments I've ever made, allowing me to self-host a ton of my side projects, Discord bots, and anything else I might want.

I've barely used half of my storage and my CPU/RAM is consistently sitting at 30-40% usage. Incredibly affordable for students like me. Plus, their interaction with students is fantastic (they throw free credits at us all the time).
