Which transformer would you use to securely send sensitive data of any size between applications in the Amazon Web Services ecosystem?

• A. AWSIoTConnector
• B. JMSSender/Receiver
• C. SQSSender/Receiver
• D. TCPIPSender/Receiver

Answer: (B)

Messaging with a broker enables secure, decoupled communication between applications, with reliable delivery and strong security controls. The JMS Sender/Receiver transformer lets you publish and consume JMS messages through a broker (such as Amazon MQ) using standard JMS APIs, which provides encryption in transit (TLS), authentication/authorization, and durable storage of messages. This setup can handle data of varying sizes because the broker stores messages and manages delivery, making it suitable for sending sensitive data between applications across AWS. Other options are more limited in this context: an IoT-specific connector is geared toward lightweight device messaging, a queue service typically imposes a fixed message size limit, and raw TCP/IP lacks built-in messaging guarantees and security features. Hence, JMS Sender/Receiver is the best fit for securely exchanging data of any size between applications in AWS.
