Consider the following situation. The source and target microservices are our two. To begin processing its own data, the source microservice needs to get in touch with the target microservice to find out if the data is ready.

Let’s assume that, among a plethora of possible design solutions to this type of issue, we opted to verify the data ready state by a straightforward HTTP request.
