    Hello Erjan,

    A common design pattern for handling orders in load-balanced EC2 instances is to use a decoupling layer between the client and your servers. A popular choice is Amazon SQS. You get the order data from the SQS queue and process them in the instances. The advantage of this is that in the event of an instance failure, orders will still persist in the queue and will not be lost.
