The video tutorial introduces the concept of microservices, focusing on two specific examples: the currency exchange microservice and the currency conversion microservice. The currency exchange microservice provides exchange rates between currencies, while the currency conversion microservice calculates the converted amount for a given quantity. The tutorial explains how these microservices interact, with the conversion service calling the exchange service to obtain current rates. This setup allows for a demonstration of key technical features such as API gateways, distributed tracing, and circuit breakers.

What is the primary purpose of introducing additional microservices in the tutorial?

• To reduce server load

• To explore features like API gateways and distributed tracing

• To enhance the user interface

• To improve database performance

What does the currency exchange microservice primarily provide?

• Currency conversion for large amounts

• Exchange rates between different currencies

• Historical currency data

• User authentication services

Which URL structure is used by the currency exchange microservice?

• /exchange/rate

• /exchange/currency

• /currency/exchange/from/USD/to/INR

• /currency/convert

What is the main function of the currency conversion microservice?

• To manage user accounts

• To convert a specified amount from one currency to another

• To provide historical exchange rates

• To store currency data

How does the currency conversion microservice obtain the exchange rate?

• It calls the currency exchange microservice

• It uses a fixed rate

• It retrieves the rate from a database

• It calculates the rate internally
