Many cloud providers offer servers that support either or both. Some examples are: ## #### Bare‑Metal Providers The best option for self-hosting is a dedicated server. | # | Provider | Type | Cheapest Server | Price | Notes | | --- | ----------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------- | --------------- | ---------- | ------------------------------- | | 1 | **[Scaleway](https://www.scaleway.com/en/dedibox/start/)** | **[Bare‑Metal](https://www.scaleway.com/en/dedibox/start/)** | START-1-M-SSD | **≈ $11** | Unmetered traffic; Paris/Warsaw | | 2 | **[OVHcloud](https://eco.ovhcloud.com/en/?_gl=1*1fvpjnw*_gcl_au*MTc0MTg2MjQxMy4xNzQ1OTIxOTEx)** | **[Bare‑Metal](https://eco.ovhcloud.com/en/?_gl=1*1fvpjnw*_gcl_au*MTc0MTg2MjQxMy4xNzQ1OTIxOTEx)** | SYS‑LE-1 | **≈ $25** | 500 Mbps; EU/CA | | 3 | **[Hetzner](https://www.hetzner.com/dedicated-rootserver)** | **[Bare‑Metal](https://www.hetzner.com/dedicated-rootserver)** | AX41 | **≈ $42** | One‑time setup fee; DE & FI | | 4 | **[Vultr](https://www.vultr.com/products/bare-metal/)** | **[Bare‑Metal](https://www.vultr.com/products/bare-metal/)** | c1.small | **≈ $120** | Hourly billing; global regions | ## #### Cloud VPS / VM Providers (Nested Virtualization) > [!WARNING] > Nested virtualization (running VMs inside VMs) may have slower performance compared to bare-metal solutions. For production workloads with heavy usage, consider using bare-metal servers for optimal performance. | # | Provider | Type | Cheapest Plan | Price | Nested Virt | Notes | | --- | ----------------------------------------------------------------------------------- | ---------------------------------------------------------------------------- | ------------------ | --------- | ----------------- | -------------------------------------------------- | | 1 | **[DigitalOcean](https://www.digitalocean.com/products/droplets)** | **[Cloud VPS](https://www.digitalocean.com/products/droplets)** | Basic Droplet 1 GB | **≈ $4** | Yes (default) | Modest perf, all regions | | 2 | **[Google Cloud](https://cloud.google.com/compute)** | **[Cloud VM](https://cloud.google.com/compute)** | n1‑standard‑1 | **≈ $34** | Yes (enable flag) | Must enable Nested Virtualization; Intel host only | | 3 | **[Microsoft Azure](https://azure.microsoft.com/en-us/products/virtual-machines/)** | **[Cloud VM](https://azure.microsoft.com/en-us/products/virtual-machines/)** | D2s_v3 | **≈ $70** | Yes (Dv3/Ev3) | VT‑x exposed by default on Gen‑2 VMs |
