A trading company handles millions of requests a day. Due to nature of its business, it requires excellent performance and reliability within its application. For this purpose, company uses a number of event-based API's hosted on various mule clusters that communicate across a shared message queue sitting within its network. Which method should be used to meet the company's requirement for its system?
Correct Answer: B
For handling millions of requests per day with high performance and reliability, JMS (Java Message Service) transactions are the most suitable method. JMS transactions ensure that messages are processed reliably and can be rolled back in case of failures, providing transactional integrity. This is crucial for a trading company where reliable message processing is critical. Using JMS transactions within Mule clusters allows for the decoupling of message producers and consumers, improving scalability and fault tolerance. JMS provides built-in mechanisms for handling transactional messaging, ensuring that messages are processed once and only once, even in the event of system failures.
