Hi With service bus you can have a reliable communication channel between dis-connected systems. i.e. if you have to pass some messages between different systems you can put your message on a service bus then whatever system requires to read that message can get it from the service bus and process it. Azure cloud has Azure service bus then there is concept of queues topics etc. I advise you to google it to read more. e.g. Lets say we have an order processing system and an order shipping system the order processing system receives and order from a customer creates order object and puts it on Azure service bus. Later when order shipping system reads this order from the service bus it processes it for shipping.
