5. Hosting (Infrastructure Layer)
Finally, your code has to run somewhere, and that’s what the hosting layer is for.
Cloud providers like AWS, Azure, and Google Cloud offer the servers and services to make your app globally accessible. You might use Docker to package your app, and Kubernetes to manage scaling and deployment.
This layer is all about reliability, scalability, and performance. If your app crashes when traffic spikes, it’s usually an issue here.
These 5 layers — UI, API, Logic, DB, and Hosting — are more than just architecture jargon. They're the backbone of nearly every modern application. When you understand how they work together, you don’t just build apps. You build software that scales, performs, and delights users.
