Realm proporciona SDK que le ayudan a conectar sus aplicaciones cliente al backend de Atlas App Services. El SDK proporciona la funcionalidad necesaria para autenticar usuarios con cualquiera de las funciones integradas. Los proveedores de autenticación llaman a las funciones Atlas y acceden directamente a una base de datos MongoDB.
El cliente de la aplicación
Al usar el SDK para acceder al backend de App Services, se comienza con un objeto App. Este objeto proporciona todas las demás funciones relacionadas con App Services. App El objeto se inicializa con el ID de la aplicación, que puede encontrar en la interfaz de usuario de App Services.

Authentication & User Management
One of the most challenging aspects of client development is implementing a robust and secure authentication system. With the Realm SDKs, however, you can use any of the App Services authentication providers with very minimal backend setup or client-side code required. With the authentication APIs, you can implement the following functionality:
Creation of new user accounts
Inicio de sesión y cierre de sesión de usuario
Multiple users logged on at the same time on the same device
Linking user accounts from different providers
Proporcionar datos de usuario personalizados
Tip
To learn how to set up authentication with different providers, see Authenticate Users - Node.js SDK.

Calling Functions
Functions enable you to define and execute server-side logic for your application. You can call these functions from your client applications via the Realm SDKs. These server-side functions can run under the context of the authenticated user, and thus honor the rules, roles, and permissions that you have assigned to your collections.
By using Functions, you provide a secure way for a variety of client applications to share complex functionality without having to reproduce that logic client-side.

Accessing MongoDB
The Realm SDKs include APIs for accessing a MongoDB Atlas instance directly. With these APIs, you can perform all of the standard CRUD operations from your client. For security, you configure server-side data access rules to dynamically determine read & write permissions for every object that is accessed.
