Master Microservices with Spring Boot and Spring Cloud - Step 13 – Connecting Currency Conversion Microservice and API G

The video tutorial covers integrating microservices with Zipkin for distributed tracing. It explains how to add necessary dependencies to the pom.xml files of the API Gateway and currency conversion service. The tutorial demonstrates manually launching microservices and checking their status, highlighting the tedious nature of this process. It then tests and verifies the microservices by firing requests and observing them in Zipkin. The video concludes with an explanation of how microservices locate the Zipkin server using default configurations and encourages further exploration of Zipkin.
