One challenge with using this approach is deciding when it makes sense to use it. API Gateway is useful for not only in blending the data of multiple services but also in the following areas: In Microservice architecture; since there is the principle of separating our large modules and our monolith applications into atomic parts that can work autonomously and independently, we may need queries that a few Microservices will come together and return results.
