Strategies for asynchronous services

Implementing asynchronous communication in a microservices application is pivotal for achieving scalability, resilience, and flexibility. By decoupling services and enabling non-blocking interactions, systems can handle varying loads and maintain responsiveness. Asynchronous communication in microservices can be achieved through various patterns and protocols:

• Message queues: Message brokers facilitate communication between services. Services send messages to queues, which are then processed by consuming services. This approach decouples services and allows for flexible message handling. For example, Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables decoupled communication between distributed components. One benefit of these services is that they are First-in-First-out (FIFO) queues. They preserve the exact order of messages and ensure each message is processed once. FIFO queues are particularly useful in financial...
