VPS vs Dedicated Server for FOSS Projects
Start with a VPS, scale to dedicated when you need it. For most FOSS projects, a €5-20/mo VPS handles everything from CI/CD to production hosting. Dedicated servers make sense when you need guaranteed performance, large storage, or hardware-level control.
Comparison Table
| Criteria | VPS | Dedicated Server |
|---|---|---|
| Entry Cost | €2-5/mo | €30-50/mo |
| Performance | Shared CPU, good for most workloads | Dedicated CPU, no noisy neighbors |
| Scalability | Scale up/down in minutes | Hardware upgrade takes hours/days |
| Control | Full root, KVM gives OS freedom | Full hardware access, custom kernels |
| Maintenance | Provider handles hardware | You're responsible for hardware monitoring |
| Storage | Limited (50-200 GB typical) | 1-20+ TB possible |
| Network | 1-10 Gbps shared | 1 Gbps dedicated typical |
| Best For | Web apps, CI/CD, dev environments | Databases, media, build farms |
When to Choose a VPS
Ideal For
- Web applications and APIs
- CI/CD runners and build servers
- Development and staging environments
- Small to medium databases
- Monitoring and dashboards
- Getting started with self-hosting
Limitations
- Shared CPU — noisy neighbors possible
- Limited disk I/O on budget plans
- RAM capped at what's allocated
- Some providers throttle sustained CPU
When to Choose a Dedicated Server
Ideal For
- Production databases with high I/O demand
- Build farms (compiling large FOSS projects)
- Media transcoding and streaming
- Virtualization hosts (run your own VPS fleet)
- Large-scale CI/CD infrastructure
- Projects needing guaranteed performance
Drawbacks
- Higher minimum cost (€30-50/mo)
- Longer provisioning (hours to days)
- Hardware failures are your problem
- Overkill for most small FOSS projects
Recommendations for FOSS Projects
Start with a VPS. Hetzner's CX21 (€5.83/mo, 2 vCPU, 4 GB RAM, 40 GB NVMe) handles most FOSS project needs: web hosting, CI/CD, database, monitoring. Deploy with Coolify for a Heroku-like experience.
Move to dedicated when: you're consistently hitting CPU limits, need terabytes of storage, want to run your own virtualization layer, or require guaranteed bare-metal performance for latency-sensitive workloads.
Hybrid works well: Run your web app and CI on VPS. Put your database and storage on a dedicated box. Use the VPS provider's network for low-latency internal communication if they're in the same data center.
