Not Everything Should Be Self-Hosted
Self-hosting evangelists sometimes go too far. While a private cloud offers privacy and cost savings, some services are better left to public cloud providers. Let's be practical about when to self-host.
Self-Host These (Private Cloud Wins)
- File Storage: Nextcloud beats Dropbox on cost at scale
- Password Manager: Vaultwarden - your passwords, your server
- Media Server: Jellyfin/Plex - no subscription, unlimited storage
- Photos: Immich - privacy for family memories
- DNS/Ad-blocking: Pi-hole - network-wide, always works
- Home Automation: Home Assistant - local, fast, private
Don't Self-Host These (Public Cloud Wins)
- Email: Deliverability is a nightmare - use Fastmail/Proton
- Video Conferencing: Jitsi works but Zoom/Meet are more reliable
- Production Databases: Use managed services for critical apps
- Global CDN: Cloudflare - can't compete with their network
- SMS/Push Notifications: Twilio, Firebase - infrastructure you can't replicate
The Decision Framework
Ask yourself:
- Is this data sensitive? → Self-host
- Do I need 99.99% uptime? → Public cloud
- Am I the only user? → Self-host
- Do I need global distribution? → Public cloud
- Is the subscription cost high? → Self-host
- Is the service complex to maintain? → Public cloud
The Hybrid Approach
Most homelabbers end up with a hybrid setup: sensitive data on private cloud, critical infrastructure on public cloud, and everything connected through a VPN. This gives you the best of both worlds.
