# Design ONEWEB Architecture

Before installing ONEWEB, you should define the **overall platform architecture** that best fits your business and application requirements.

ONEWEB is an **enterprise‑grade application development platform** built on **Java EE technology** and follows a **three‑tier architecture** consisting of:

* Web Tier
* Application Tier
* Database Tier

This layered architecture provides clear separation of concerns and supports scalability as system usage grows.

In addition to traditional deployments, ONEWEB also supports **containerized architecture** for cloud environments. Multiple deployment models are available to address different levels of availability, scalability, and operational complexity.

At a high level, the standard ONEWEB architecture options include:

* **Standalone Architecture**
* **High Availability Architecture**
* **Cloud Architecture**

Each architecture option is explained in detail in the following sub‑sections.
