🚀 Deploying & Securing ASP.NET Core Applications

By Samim Hossain · April 5, 2026 · 3 min read · 473 views

(Docker, Nginx, HTTPS & Production Best Practices)

Writing code is only half the job.
Deployment, security, and reliability decide whether your ASP.NET Core application survives in production.

In this article, we’ll deploy an ASP.NET Core API using Docker, secure it with Nginx + HTTPS, and apply real-world production hardening techniques.

Production Deployment Architecture

plaintext

Client (Browser / Mobile)
        ↓ HTTPS
     Nginx (Reverse Proxy)
        ↓
   ASP.NET Core (Docker)
        ↓
    Database / Cache

Why Use Docker?

Environment consistency
Easy scaling
Faster deployments
CI/CD friendly
