A Cloud VPS is a virtual machine with dedicated CPU, RAM, disk space, and root access. Unlike shared hosting where resources are distributed, your VPS resources are isolated—no "noisy neighbor" issues. This flexibility makes VPS suitable for almost any server-based workload. Here are the most common use cases UnderHost customers deploy.
Web hosting multiple sites
Host multiple websites on a single VPS with a control panel for easy management.
Common setup:
- 2-4 GB VPS with Nginx + PHP-FPM + MySQL/MariaDB
- 5-20 medium-traffic websites per VPS
- aaPanel, HestiaCP, or cPanel control panel for domain management
Recommended control panels:
- aaPanel (recommended): Free, lightweight, easy to use, built-in backups
- HestiaCP: Free, modern interface, email included
- cPanel: Industry standard, $10-15/month license, most features
Cost comparison:
- VPS 2GB: $15-25/month → Can replace 10+ shared hosting accounts ($5-10 each)
- No per-domain fees; host unlimited domains on one VPS
- Easily add more sites as you grow
See: Install aaPanel for setup guide.
High-traffic WordPress sites
When WordPress outgrows shared hosting, a VPS is the natural upgrade.
Why WordPress needs VPS:
- Shared hosting CPU/RAM limits trigger throttling at 10,000-50,000 monthly visitors
- VPS offers dedicated resources + full control over PHP, caching, database
- Install caching plugins, enable Redis, tune memory—all unavailable on shared hosting
Recommended VPS size: 4 GB RAM with at least 2 CPU cores
Stack for WordPress on VPS:
- Web server: Nginx (faster than Apache)
- PHP: PHP-FPM (more efficient than mod_php)
- Database: MySQL 8.0 or MariaDB 10.5+
- Caching: Redis for object cache (huge performance boost)
- Reverse proxy: Cloudflare or CDN for static content
Performance:** Properly configured VPS with Redis can handle 1M+ monthly visitors.
See: WordPress caching and Server optimization.
Run custom applications
Shared hosting cannot run most modern frameworks. VPS can run almost anything.
Common application stacks on VPS:
- Node.js applications: Express, Next.js, Vue, React backends
- Use PM2 or systemd to manage app as service
- Use Nginx as reverse proxy in front of app
- 1-2 GB VPS sufficient for small Node apps
- Python applications: Django, Flask, FastAPI
- Use Gunicorn or uWSGI application server
- Use Nginx to proxy requests
- 2 GB VPS recommended for Django/FastAPI
- Ruby on Rails: Full web framework with database
- Use Puma app server + Nginx
- 2-4 GB VPS typical
- Go/Rust applications: High-performance compiled binaries
- Can run directly on 512MB-1GB VPS
- Minimal resource requirements
Deployment workflow:
- SSH into VPS
- Install runtime (Node, Python, etc.)
- Clone application from Git
- Install dependencies (npm, pip, etc.)
- Configure systemd service to auto-start app
- Point Nginx at app (reverse proxy)
Game servers
Host private game servers for your community or organization.
Common games on VPS:
- Minecraft: 4-8 GB VPS (50-100 players), place in same region as players
- Counter-Strike 2: 2-4 GB VPS per server
- Valheim: 1-2 GB VPS, very lightweight
- Rust: 4-8 GB VPS, resource-heavy
- ARK: Survival Evolved: 8+ GB for reasonable player counts
VPS advantages for game servers:
- Full control over server settings, mods, plugins
- Lower cost than game hosting sites ($10-30/month vs $30-100/month)
- Choose server location for best latency to players
- Easy to backup and restore world saves
Note: Game servers are I/O-intensive (disk reads/writes for world data). SSD storage is essential.
Infrastructure and privacy
VPS excels at infrastructure and privacy-focused workloads.
- VPN server: WireGuard or OpenVPN for private VPN access
- 1 GB VPS enough for personal use
- No third-party provider can see your traffic
- Choose server location (Canada, Netherlands, Hong Kong, etc.)
- Mail server: Self-hosted email for your domain
- Full control over data; no reliance on Gmail/Office365
- Postfix + Dovecot typical stack
- 2 GB VPS recommended
- Requires proper SPF/DKIM/DMARC setup for deliverability
- DNS server: Host your own authoritative DNS
- Use BIND or PowerDNS
- Minimal resource requirements (512MB VPS sufficient)
- File storage / Nextcloud: Self-hosted cloud storage
- Private alternative to Dropbox/OneDrive
- 2 GB RAM, 50+ GB SSD recommended
Development and testing
Use a VPS as a sandbox for experimentation and testing.
- Staging environment: Clone production to staging, test updates before pushing live
- CI/CD pipeline: Automated testing and deployment
- Testing new software: Try databases, web servers, frameworks without affecting production
- Learning Linux: Practice system administration in a safe, isolated environment
Best practice: Snapshot your VPS before experiments. If something breaks, roll back to snapshot instantly.
Choosing the right VPS size
Recommended sizing by use case:
| Use case | Recommended RAM | CPU cores | Disk |
|---|---|---|---|
| Single WordPress site | 2 GB | 2 cores | 40-60 GB |
| Multiple websites (5-10) | 2-4 GB | 2 cores | 80-120 GB |
| High-traffic WordPress | 4-8 GB | 4 cores | 100+ GB |
| Node.js / Python app | 1-2 GB | 1-2 cores | 40-80 GB |
| Game server (Minecraft) | 4-8 GB | 2-4 cores | 80+ GB SSD |
| VPN or mail server | 1-2 GB | 1 core | 20-40 GB |
| Multiple services | 8+ GB | 4+ cores | 200+ GB |
Start small, upgrade as needed: Begin with smallest size that fits your use case. Most VPS providers allow easy upgrades (add more RAM/CPU) when demand increases.
The list above is just the common use cases. VPS can literally run any Linux-based software: databases, message queues, search engines, machine learning models, Docker containers, Kubernetes clusters, and much more. If you can think of it and it runs on Linux, you can run it on a VPS.
