Question
You are developing a new image processing application that needs to handle various tasks, such as resizing, cropping, and watermarking images. You also need to monitor the workflow and ensure that it scales efficiently when there are large volumes of images. You want to automate the image processing tasks and workflow monitoring with the least effort. What should you do?
A. Employ Cloud Composer to manage the image processing workflows. Use Dataproc for workflow monitoring and analytics.
B. Use Cloud Run to deploy the image processing functions. Use Apigee to expose the API. Use Cloud Logging for workflow monitoring.
C. Implement Workflows to orchestrate the image processing tasks. Use Cloud Logging for workflow monitoring.
D. Use Cloud Build to trigger Cloud Functions for the image processing tasks. Use Cloud Monitoring for workflow monitoring.
Answer
C. Implement Workflows to orchestrate the image processing tasks. Use Cloud Logging for workflow monitoring.
Explanation
Google Cloud Workflows provides a fully managed, serverless platform for orchestrating and automating complex processes. It allows you to define and execute workflows using a YAML-based syntax. Workflows supports various GCP services and APIs, making it an ideal choice for automating image processing tasks such as resizing, cropping, and watermarking.
By using Workflows, you can define a series of steps that include invoking Cloud Functions or other GCP services to perform the required image processing tasks. Workflows handles the orchestration and ensures that each step is executed in the correct order. It also provides built-in error handling and retry mechanisms.
For monitoring the workflow execution, Cloud Logging is the recommended solution. Cloud Logging is a fully managed logging service that allows you to store, search, analyze, and alert on log data and events from GCP. When you use Workflows, the execution logs are automatically sent to Cloud Logging. You can then use the Cloud Logging interface or API to monitor the workflow progress, track errors, and set up alerts based on specific log events.
The other options are not as suitable for this scenario:
A. Cloud Composer is primarily used for orchestrating Apache Airflow workflows, which may be overkill for simple image processing tasks. Dataproc is used for running Apache Hadoop and Spark clusters, which are not directly relevant for workflow monitoring.
B. Cloud Run is suitable for deploying stateless containers, but it doesn’t provide built-in workflow orchestration capabilities. Apigee is an API management platform and not directly related to workflow monitoring.
D. Cloud Build is primarily used for continuous integration and continuous delivery (CI/CD) pipelines, not for orchestrating image processing workflows. Cloud Monitoring is used for monitoring infrastructure and application metrics, but Cloud Logging is more suitable for logging and monitoring workflows.
By using Cloud Workflows and Cloud Logging together, you can automate the image processing tasks and workflow monitoring with the least effort while ensuring scalability and efficiency.
