# Architecture and operations

> Guidance for partner plugins on interoperability, deployment, and operational requirements.

Partner plugins should use the documented interfaces and operational requirements of the Lerian products they integrate with.

## Programming language and architecture

***

Choose the programming language and architecture that fit your plugin. Design the integration around the published interfaces of the Lerian product it connects to.

## Deployment models

***

Lerian supports two deployment models:

* **BYOC**: the customer operates the infrastructure in its own cloud or on-premises environment.
* **Lerian Cloud**: Lerian operates the managed cloud environment.

Make plugin deployment requirements explicit and validate them with the integration owner for the selected model.

## Observability

***

Document the logs, metrics, tracing, and operational signals that an integration needs. Agree on the required telemetry format and destination with the product owner before deployment.

## Auditability and traceability

***

For a plugin that handles financial data, document its audit behavior, data-retention requirements, and any integrity mechanism. Confirm the applicable requirements with the product owner before integration.

## Authentication and authorization

***

Access Manager is an optional Enterprise feature that products and plugins can use for access control. Document the authentication behavior implemented by the product and plugin that are being integrated.
