You want to minimize the latency of this process. What should you do?

  • A. Use Workflows to call the functions, and use callbacks to handle the execution logic.
  • B. Use Workflows to call the functions, and use conditional jumps to handle the execution logic.
  • C. Use Cloud Composer to call the functions, and use an Apache Airflow HTTP operator to handle the execution logic.

Selected Answer: B
Why Workflows + Conditional Jumps (Option B): • Workflows is Google Cloud’s native orchestration service, ideal for chaining Cloud Functions and APIs. • It supports low-latency orchestration with native conditional logic, which allows dynamic flow control based on function outputs. • Conditional jumps in Workflows allow execution flow to branch or jump based on runtime evaluations — perfect for order fulfillment logic.

Selected Answer: B
Workflows is a service in Google Cloud that allows you to orchestrate serverless functions and services in a sequence or in parallel. It is specifically designed for orchestrating tasks like this in a simple and efficient manner. Using conditional jumps within Workflows allows you to dynamically control the flow based on the outputs of the functions. This means you can easily determine which function to call next based on the results of the previous steps.
