Certified Integration Architect Exam - Question 23

Universal Containers (UC) currently owns a middleware tool and has developed an API-led integration architecture with three API tiers. The first tier interfaces directly with the systems of engagement, the second tier implements business logic and aggregates data, and while the third tier interfaces directly with the systems of record. Some of the systems of engagement will be a mobile application, a web application, and Salesforce.

UC has a business requirement to return data to the systems of engagement in different formats while also enforcing different security protocols.

What should an integration architect recommend to meet these requirements?

Show Answer
Correct Answer: CD

The first tier of an API-led architecture, often referred to as the Experience Tier, is designed to handle different types of consumers, such as mobile applications, web applications, and Salesforce. This tier is responsible for adapting the presentation of data and enforcing different security protocols as needed by different systems of engagement. Implementing the necessary formatting and security at this layer ensures that the business logic and data aggregation tiers remain consistent and unaffected by the varying requirements of the consuming applications.

This first layer, called Experience Layer in the API-Led - is meant to deal with different type of consumers (format, authentication, etc) while the other two layers remain the same. https://blogs.mulesoft.com/api-integration/patterns/patterns-to-debunk-api-led-connectivity-myths/
