| One-Tier Architecture |
A single-layer architecture where the application and database reside on the same machine. |
| Two-Tier Architecture |
Divides the application into a client and a server, with the database usually residing on the server. |
| Three-Tier Architecture |
Separates the application into three layers: presentation, logic, and data, typically hosted on different servers. |
| N-Tier Architecture |
Extends the three-tier architecture to include more layers, enhancing scalability and flexibility. |
| Serverless Architecture |
Runs applications without managing the underlying infrastructure, relying on cloud services to handle server provisioning and scaling. |
| Microservices Architecture |
Breaks down applications into small, loosely coupled services that can be developed, deployed, and scaled independently. |
| Event-Driven Architecture |
Uses events to trigger and communicate between decoupled services, allowing for more responsive and scalable systems. |
| Hybrid Architecture |
Combines multiple architectural styles to leverage the benefits of each, often mixing on-premises and cloud environments. |
