Which principle is commonly found in both Service-Oriented Architecture (SOA) and API-led connectivity?

The principle of service reusability is fundamental to both Service-Oriented Architecture (SOA) and API-led connectivity. This concept emphasizes the ability to create services that can be used across different applications, enabling organizations to save time, reduce redundancy, and enhance efficiency in development.

In SOA, the goal is to design services in a way that they can be easily integrated and reused by various applications within an enterprise, promoting a modular approach to building software solutions. Similarly, API-led connectivity encourages the development of APIs that expose specific functionalities or data, allowing these APIs to be utilized by multiple clients or applications. This aspect fosters a more agile development process as teams can leverage existing APIs rather than building new services from scratch.

Utilizing reusable services or APIs also supports better maintenance practices, as updates can be made to a single service without impacting all the consumers directly, as long as the service interface remains consistent. This aligns with the core principles of both architectures aiming for efficiency, flexibility, and maintainability in system design.
