In a previous post, I introduced the concept of queues and their usage. Now, I will explain how to implement an SQS consumer and publisher using C# and .NET.
SQS (Simple Queue Service) is an Amazon Web Services offering that enables the sending, storing, and receiving of messages between software components at any volume, ensuring no message loss and eliminating the need for immediate availability of other services.
A queue is a dynamic data structure that allows for the removal of elements and the insertion of new objects. More specifically, a queue is a structure that follows the rule of operation where whenever there is a removal, the element removed is the one that has been in the structure the longest. Queues follow the FIFO (First In, First Out) principle, where the first element added is the first to be removed. This is useful for many applications in distributed systems, where the order of operations is important.
