No reverse proxy = exposure to attacks
No process manager = app crashes = downtime

👉 Deployment is not just technical—it directly affects:

Business uptime
Customer experience
Revenue continuity

FAQ

1. Do I need a VPS to deploy a Flask app?

A VPS is not strictly required, but it is the best option for production because it provides dedicated resources, control, and better performance compared to shared hosting.

2. Can I deploy Flask without Gunicorn?

You can, but it is not recommended for production since Gunicorn is designed to handle multiple requests efficiently and reliably.

3. Why do I need Nginx?

Nginx acts as a reverse proxy that improves performance, handles client requests efficiently, and adds a layer of security between users and your application.

4. Is SSL necessary for my Flask app?

Yes, SSL is essential for securing data between your users and your application, especially if you handle logins, payments, or sensitive data.

5. How much does it cost to host a Flask app in Kenya?

Costs vary depending on the VPS provider and specifications, but you can expect to pay anywhere from a few thousand shillings monthly, with higher costs for managed services.

6. Should I use managed or unmanaged VPS for Flask deployment?

Managed VPS is better if you want a hassle-free setup with support, while unmanaged VPS is suitable if you have the technical expertise to manage everything yourself.

7. Can I scale my Flask app later?

Yes, you can scale by upgrading your VPS, adding load balancers, or moving to containerized or cloud-native architectures.

8. What happens if my Flask app crashes?

Without a process manager like systemd or supervisor, your app will stay down, but with proper setup it can restart automatically.

9. Do I need a domain name?

A domain is not required but is recommended for accessibility, branding, and SSL configuration.

10. How do I monitor my app after deployment?

You can use logging, monitoring tools, and uptime checks to ensure your application is running smoothly and detect issues early.
