Real-World Use Case: Web Server
Let’s consider a real-world scenario where we need to set up a web server for a small e-commerce site with 100 users and 500 actions per day.
- Setup complexity: Caddy takes around 2 hours to set up, while Traefik takes around 5 hours due to its more complex configuration options.
- Ongoing maintenance burden: Caddy requires minimal maintenance, with automatic SSL renewal and updates handled by the community. Traefik also has automatic SSL renewal, but its more complex configuration options may require occasional manual intervention.
- Cost breakdown: For 100 users and 500 actions per day, Caddy’s cost is $0 (free, open-source), while Traefik’s cost is also $0 (free, open-source), but with optional paid support starting at $1,000 per year.
- Common gotchas: With Caddy, be aware of its limited scalability and potential issues with very high-traffic sites. With Traefik, be aware of its steeper learning curve and potential issues with complex configuration options.
