The video tutorial covers setting up a microservices application with an API gateway and naming servers. It demonstrates configuring Zipkin using Docker Compose and integrating it with other microservices for distributed tracing. The tutorial includes launching and testing multiple applications, ensuring they are registered and functioning correctly. It also explores using Zipkin for tracing and discusses the potential benefits of incorporating RabbitMQ to enhance system resiliency, allowing microservices to queue information even if the tracing server is down.

What is the primary purpose of using Docker Compose in the context of this tutorial?

• To manage multiple Docker containers as a single application

• To create virtual machines

• To compile code

• To design user interfaces

Which port is configured for Zipkin in the Docker Compose setup?

• 5432

• 3306

• 9411

• 8080

In configuring the microservices, what should 'localhost' be replaced with for the Zipkin server?

• api-gateway

• localhost

• zipkin-server

• currency-exchange

What is the purpose of adding RabbitMQ in the microservices architecture?

• To increase the speed of the API gateway

• To enhance user interface design

• To improve database performance

• To add resiliency to the distributed tracing setup

What is verified after launching the applications in the final section?

• The memory usage of the server

• The speed of the API gateway

• The registration of all services

• The user interface design
