Section 1:  In the following video lessons, he will learn how to use spring cloud gateway to aroud incoming requests to destination Ceressus. When my services start up, they register themselves with Eureka Discovery Service, Eureka becomes aware of each of your micro series and their address. And when we need to scale up, we can start 10 more micro services and each of them will register with Eureka Discovery Service automatically and Eureka will know their addresses as well.
