Jonathan automated routine tasks by sending information from one system to a gateway on the VPC to trigger actions from multiple sources. Which automation technique did he implement?

• A. Scripting
• B. Webhooks
• C. Batch jobs
• D. APIs

Answer: (D)

The main idea here is programmatic, cross-system communication through a centralized, controlled entry point. APIs provide a standardized way for one system to request actions from other systems, pass data, and receive responses. By placing a gateway on the VPC, Jonathan created a single, secure conduit that can route those API calls to multiple backend services and trigger their actions as part of an automated workflow. This setup is ideal for coordinating tasks across several sources and services without being tied to a single application or environment.

Scripting, while useful for automating tasks, typically runs within a particular environment or host and doesn’t inherently enable standardized, cross-system interactions through a central gateway. Webhooks are event-driven notifications pushed to a specific endpoint, which can trigger actions but usually involve one recipient and don’t provide the centralized orchestration across multiple sources that an API gateway enables. Batch jobs are about processing large sets of data on a schedule, not real-time or multi-service orchestration.
