The correct Answer is C. Amazon SQS is a fully managed message queuing service that allows you to decouple and scale applications by buffering the incoming data. This would ensure that data is stored in a reliable, scalable queue until the web application is ready to process it. SQS provides high availability and fault tolerance, and guarantees that no data will be lost, as the messages remain in the queue until they are processed. The web application can poll the SQS queue for new messages and process them at its own pace, preventing the application from being overwhelmed by large volumes of tracker data. Operational overhead is minimal because SQS is a fully managed service. The application only needs to poll the queue for messages, and there is no need to manage infrastructure.

Answer: C Amazon SQS provides a reliable and scalable way to decouple the components of the application. By using a queue, the incoming tracker data can be buffered, ensuring that if the web application is overwhelmed with data, the messages will still be retained in the queue until they can be processed.
