Description: Third-party integration in the context of serverless computing refers to the process of connecting applications and services that operate without the need to manage physical or virtual servers with external APIs and services. This approach allows developers to leverage additional functionalities and data from various applications, facilitating the creation of more robust and efficient solutions. Serverless computing, which abstracts the underlying infrastructure, enables developers to focus on business logic and feature implementation, while third-party integration expands the capabilities of these applications by incorporating services such as databases, authentication systems, messaging services, and more. This integration is achieved through API calls, allowing serverless applications to interact seamlessly and scalably with external services. The relevance of this practice lies in its ability to accelerate development, reduce operational costs, and enhance the end-user experience by offering functionalities that would otherwise require extensive and complex development.
