Here's what I use mine for: > Hosting my website (with CloudFlare in front) > A gateway into my network (almost all ports are open to the RPi including SSH). I can ssh in and then every device on my network is configured to accept connections from it. Hitting my devices directly (over v6, for instance) would be rejected by firewalls and such. > Personal Cloud: I use BitTorrent sync to move files around my computers. Sometimes my desktop / laptop aren't on at the same time. I solved this problem by putting BTSync on my RPi. It's online 24/7 so my files are always accessible. > MySQL server (for development). Ideas I have floating around: > Possibly hosting my email > Internal services like Squid caching. > Server-Side Development. It's a tight environment (ram is limited, cpu is fairly slow) so it forces you to build lightweight programs. If it can run well on a RPi, it's probably fine on a VPS. > Monitoring/graphing uptime/latency -- My router doesn't do this for me. > Scheduling backups (possibly via rsync?) Your RPi is basically a home server. Use it to control devices in your house and do automation.
