![]() In Laravel, you can implement message queues using Laravel Queue Workers. Load Balancing: By distributing messages across multiple microservice instances, you can balance the load efficiently. Reliability: Even if one microservice fails temporarily, messages remain in the queue and can be processed when the service recovers. For instance, if the Payment Service receives high traffic, you can add more instances of that service to process payments faster. Scalability: You can scale each microservice separately based on its load. For example, if the Payment Service is temporarily down, orders can still be created, and other services won't be affected. When it receives an order message, it sends a confirmation email or SMS to the customer.ĭecoupling: Each microservice can work independently and at its own pace. The Notification Service watches the "OrderQueue" for new messages as well. Similar to the Payment Service, the Shipping Service also monitors the "OrderQueue."Upon detecting a new order message, it generates the shipping label and prepares the items for shipping. ![]() It then processes the payment asynchronously and independently from the Order Service. When a new order message appears, the Payment Service retrieves it from the queue. The Payment Service continually monitors the "OrderQueue" for new messages. Instead of immediately processing the payment, creating shipping labels, and sending notifications, the Order Service places a message (order data) onto a message queue called "OrderQueue." When a customer places an order, the Order Service receives the request. In this scenario, message queues can be utilized to ensure that these tasks are processed asynchronously and independently by each microservice. Notification Service: Send an email or SMS to the customer, confirming the order. Shipping Service: Prepare the items for shipping and generate a shipping label. Payment Service: Verify payment details and process the payment. Order Service: Create an order record in the database. For instance, the following actions must be taken after an order is created: ![]() Use Case: Several steps need to be completed across various microservices when a customer places an order. Though the project was vast scale, I will only focus on the following Recently successfully architectured a message queue for one of my client's e-commerce projects in Europe. ![]()
