According to MuleSoft, which principle is common to both Service Oriented Architecture (SOA) and API-led...

Comprehensive and Detailed Explanation:

The Shared Goal:Both SOA (an older architectural style) and API-led Connectivity (MuleSoft's modern approach) aim to solve the problem of "Spaghetti Code" by breaking monolithic applications into smaller pieces.

Reusability:The core promise of both isReusability.

SOA:Aimed to create reusable web services (often SOAP).

API-led:Focuses on creating reusable Assets (System, Process, and Experience APIs) that can be discovered and self-served by other teams.

The Difference:While thegoal(Reuse) is the same, SOA often failed due to heavy governance and lack of discoverability. API-led connectivity improves on this by emphasizingconsumptionandself-servicevia the Anypoint Exchange.
