Now we will see what message attributes in AMQP perspective is. So, Exchange is the Middleman of the message routing process and route messages in different Queues based on the binding producer's mention. AMQP does not just make it possible for these dissimilar systems to speak with each other, yet additionally empowers different products that actualize AMQP to exchange data. There is a many of software running on many operating systems worked with different programming languages running on different hardware structures and virtual machines.

To empower interoperability between different technologies and stages.To deliver an open standard for informing middleware.Also, the interoperability problem that those products tried to solve resulted in creating new proprietary message protocols which do not interoperate with others, therefore resulting in ‘vendor lock-in.’ĪMQP has various design areas, but two of the most vital are: To overcome these, few products like WebSphere MQ and Tibco came into pictures, but those are also not fully loosely coupled and most importantly those are very costly in terms of the license cost. Traditional messages which we are familiar about with JMS has few limitations mostly it expects homogeneous publisher and consumers to interact with the message broker and the message format was somehow tightly coupled with the API we choose to interact like JMS in Java world.
