What is an effective method for sending notifications from a web application that uses Azure Cosmos DB?

1. Implement Azure Logic Apps with the SendGrid connector

2. Use a standard function app with an Event Grid binding

3. Create a SQL database trigger

4. Employ Azure Functions with a Service Bus trigger

The correct answer is: Implement Azure Logic Apps with the SendGrid connector

Using Azure Logic Apps with the SendGrid connector is an effective method for sending notifications from a web application that utilizes Azure Cosmos DB. This approach allows you to easily automate the process of sending emails or messages to users based on specific triggers or actions within your application. Azure Logic Apps provide a straightforward and visual interface for building workflows that can integrate with various services, including sending notifications through SendGrid, which is a powerful tool for managing email communications. By setting up a logic app with the SendGrid connector, you can define the conditions under which notifications should be sent, such as when a new document is created in Cosmos DB, ensuring timely and relevant communication with your application users. Additionally, this method enhances the scalability and maintainability of notification features, as Logic Apps can handle varying workloads and you don't need to manage the underlying infrastructure. The integration capabilities of Logic Apps allow for easily adapting the notification process as the application's requirements evolve. The other options might not offer the same level of ease and flexibility for sending notifications. For example, while using Event Grid or Service Bus with Azure Functions may provide custom event-driven solutions, they typically require more development effort and a deeper understanding of asynchronous processing patterns. Creating a SQL database trigger, on the other hand, could
