The hosting industry pushes two narratives: “shared hosting is dead” and “VPS is too complex for normal people.” Neither is true. This comparison breaks down the real differences so you can decide based on your actual needs.
The fundamental difference
Shared hosting puts hundreds (or thousands) of sites on one server. They share CPU, RAM, disk I/O, and an IP address. The hosting company manages everything — you cannot change server config, and you are limited to what the control panel offers.
VPS (Virtual Private Server) gives you a guaranteed share of a physical server’s resources. Your CPU cores, RAM, and disk are allocated to you and only you. You have root access and can install anything. You also have responsibility for everything — security, updates, configuration.
Performance
On a typical entry-level plan serving a WordPress site:
| Metric | Shared Hosting ($5-10/mo) | VPS ($6-24/mo) |
|---|---|---|
| TTFB (cached) | 50-200 ms | 10-30 ms |
| TTFB (uncached) | 200-800 ms | 40-120 ms |
| Concurrent users | 5-20 before slowdown | 50-500 depending on config |
| Guaranteed RAM | None (burst only) | 1-8 GB dedicated |
| I/O performance | Variable (noisy neighbour) | Consistent |
| Traffic limits | ”Unlimited” (not really) | 1-20 TB metered |
The key word in shared hosting is “variable.” Your site might be fast at 3am and slow at 3pm because other sites on the server are busy. A VPS gives you consistent performance because your resources are dedicated.
Cost comparison
Running a WordPress site for 3 years:
| Expense | Shared Hosting | Self-managed VPS | Managed VPS |
|---|---|---|---|
| Hosting | $180-360 ($5-10/mo) | $180-540 ($5-15/mo) | $504-1,800 ($14-50/mo) |
| SSL | Free (cPanel AutoSSL) | Free (Let’s Encrypt) | Included |
| Backups | Usually included | Your time to configure | Included |
| Usually included | Separate ($0-60/yr) | Separate ($0-60/yr) | |
| 3-year total | $180-360 | $180-600 + time | $504-1,860 |
Shared hosting is the cheapest option. A self-managed VPS can be similarly priced if you use budget providers (Hetzner €4.50/month). A managed VPS costs more upfront but saves time.
Security
| Threat | Shared Hosting | VPS |
|---|---|---|
| Other sites on server | Risk — one compromised site can affect others | Isolated — your VM is separate |
| Brute force attacks | Host-level protection included | You configure Fail2Ban or similar |
| Malware | Host may scan and clean automatically | Your responsibility |
| Zero-day patches | Host handles server patches | Your responsibility |
| DDoS | Basic protection included | You configure (or use Cloudflare) |
Shared hosting’s security model is: the host handles it, but you are vulnerable to other tenants. A VPS security model is: you handle it, but you are isolated from other tenants. Neither is inherently more secure — it depends on the implementation.
Maintenance burden
| Task | Shared Hosting | VPS |
|---|---|---|
| Server updates | Host handles | You (weekly) |
| PHP updates | Host handles | You configure |
| Security patches | Host handles | You (promptly) |
| Database tuning | Host’s default | You optimise |
| Caching setup | Plugin only | Full control (Redis, FastCGI cache, Varnish) |
| Backup configuration | Usually automatic | You set up and test |
| Monitoring | Not available | You configure |
The maintenance burden is the real cost of a VPS. Plan for 2-4 hours per month for a well-configured single-site server. More during the first month of setup.
The migration trigger points
Move from shared hosting to a VPS when:
- Your site feels slow consistently, not just during traffic spikes
- You hit arbitrary limits: file count, inode limits, database size, cron job restrictions
- You need custom server software: specific PHP extensions, Redis, Elasticsearch, FFmpeg
- You want to run multiple sites efficiently with isolation (Docker or separate PHP pools)
- You need consistent performance for an ecommerce site where every 100ms matters
Stay on shared hosting when:
- Your site is low-traffic and loads fine
- You do not want to learn server management
- You need email included with your hosting
- You value simplicity over control
- Your site is mostly static — consider static hosting instead of a VPS
The middle ground
If you are technically comfortable but do not want full server administration:
- Cloudways: Managed cloud VPS, $14+/month, handles server management
- RunCloud: Server control panel for your own VPS, $8+/month + VPS cost
- SpinupWP: WordPress-focused server manager, $12+/month + VPS cost
These give you most of the VPS benefits without the full maintenance burden.
Verdict
VPS wins for performance and control. If you are reading CronDaily, you are probably the kind of person who should be on a VPS. The performance difference is dramatic, the cost is often similar or cheaper, and the control is empowering.
Shared hosting wins for simplicity and cost. If you want to pay $5/month and never think about server administration, shared hosting (or better, a managed WordPress host like Kinsta or WP Engine) is the right choice.
The real advice: start on shared hosting. When you outgrow it — and you will know when — migrate to a VPS. The migration is well-documented, takes a weekend, and is one of the most impactful upgrades you will make.
