Internal communication with message queues in E-commerce

Ever wonder how online stores manage to handle many order in the same time, from the moment you click “Buy” to the package arriving at your door? Behind the scenes, e-commerce platforms use various tools, often including the message queue, to manage this process.

When you hit the “Place Order” button on a website, a bunch of things start happening.

• Your order details are sent to something called a message queue, which is like a waiting room for orders. It keeps everything organized until it’s time to process your order.

• The message added to the queue will in turn be received by the subscriber of the queue, which purpose is to update inventory levels. This makes sure they don’t sell more than they have.

• Once your order is confirmed, a message containing payment details is added to the queue, awaiting the attention of the payment service. Upon receiving the payment details, the subscribing service swiftly processes the payment.

• Then, your order details go to the shipping department so they can get your package ready to send to you. This part also happens through the message queue, making sure everything stays organized.
