# Cloud Architecture

**Cloud Architecture** is an alternative deployment model for hosting ONEWEB applications on a **cloud provider**.\
This architecture is designed to provide flexibility, scalability, and operational efficiency by leveraging cloud infrastructure instead of on‑premises hardware.

By adopting a cloud‑based deployment, organizations can benefit from:

* Reduced server maintenance effort
* Lower hardware investment cost
* Faster provisioning and scalability

Cloud Architecture is suitable for organizations that prefer cloud‑native or hybrid operational models.

### Cloud Service Models

When deploying ONEWEB in a cloud environment, several cloud service models may be considered:

* **Infrastructure as a Service (IaaS)**\
  Provides virtualized infrastructure resources such as compute, storage, and networking.
* **Platform as a Service (PaaS)**\
  Provides a managed platform environment for running applications.
* **Software as a Service (SaaS)**\
  Delivers applications as fully managed services to end users.

Based on customer and business requirements, **ONEWEB can be hosted on the cloud as a PaaS or SaaS solution**.

The selected cloud service model determines the level of control, responsibility, and operational effort required.

### Reference Architecture Overview

The following diagram illustrates a high‑level view of a typical ONEWEB cloud deployment:

This diagram represents the **logical cloud architecture**, showing how ONEWEB platform components are hosted and integrated within a cloud environment.\
The diagram intentionally does not describe implementation details such as container layout or orchestration mechanisms.

### Relationship to Container‑Based Deployment

In cloud environments, ONEWEB is commonly deployed using a **container‑based architecture** to improve portability, scalability, and operational consistency.

While this section focuses on **why and when to use Cloud Architecture**, the detailed structure of containerized deployment—including individual platform components and orchestration—is explained separately in the following section:

* **Container Structure**

### When to Choose Cloud Architecture

Cloud Architecture is recommended when:

* Infrastructure maintenance overhead needs to be minimized
* Applications require flexible scaling and rapid provisioning
* Cloud services are preferred over on‑premises deployments
* ONEWEB is delivered to customers as a managed platform or service

Compared to Standalone and High Availability architectures, Cloud Architecture provides greater flexibility and aligns well with modern cloud‑native deployment strategies.
