Question
You work for a company that operates an ecommerce website. You are developing a new integration that will manage all order fulfillment steps after orders are placed. You have created multiple Cloud Functions to process each order. You need to orchestrate the execution of the functions, using the output of each function to determine the flow. 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.
D. Use Cloud Composer to call the functions, and use an Apache Airflow operator to handle the execution logic.
Answer
B. Use Workflows to call the functions, and use conditional jumps to handle the execution logic.
Explanation
Google Cloud Workflows is the best choice for orchestrating the execution of multiple Cloud Functions for this ecommerce order fulfillment integration. Workflows allows you to define a series of steps and conditionally jump between them based on the output of each function. This gives you fine-grained control over the execution flow.
Using conditional jumps in Workflows to handle the execution logic will minimize latency because:
- Workflows executes steps serverlessly with high performance and scalability
- Conditional jumps allow skipping unnecessary steps based on function outputs
- Workflows can pass data directly between function steps without intermediaries
The other options are not ideal:
- Callbacks with Workflows add complexity and potential delays in the execution
- Cloud Composer and Apache Airflow have higher overhead and latency than native Workflows
- HTTP operators with Composer introduce additional network hops and latency
So in summary, using Google Cloud Workflows to orchestrate the Cloud Functions, with conditional jumps to define the execution logic, will provide the most direct and efficient pipeline to minimize latency for this ecommerce order fulfillment integration.
