Next, you’ll need to create a BigQuery table to contain metadata about the images that are extracted by the Cloud Vision API. BigQuery is Google’s data warehouse designed for analyzing petabytes worth of data using SQL and is often used for historical analysis, time series data, and other scenarios where SQL-like data can be retained for a long time with fast retrieval. Ensure that the Cloud Functions API, the Cloud Vision API, and the BigQuery API are all enabled.On the Library page, search for each API mentioned above and enable them with the blue manage button. You will see an API Enabled label after it has been enabled successfully. (image 2).Select the hamburger menu from the upper left-hand corner of the Google Cloud Platform console.Once your project is set up, you’ll need to enable a few APIs, specifically the Cloud Functions API, the Cloud Vision API, and the BigQuery API. To enable those APIs within your project: NET, or Ruby if you prefer. Be sure your environment is set up to develop scripts on the Google Cloud SDK with Python using the links above. If you are not familiar with setting up a Google Cloud Platform project, click here to learn how to do so. During this tutorial, we will be using gcloud to deploy our functions and Python to write the script. You could also use Node.js, Go, Java. To begin, you will need a Google Cloud Platform project with a few APIs enabled. In this step-by-step guide, we’ll walk through an example scenario that uses Google Cloud Functions, Google Cloud Storage, Google Cloud Vision API, and Google BigQuery. The purpose of the function will be to pass an image to the Vision API/AI and obtain information about it for later analysis. We’ll set up a cloud function in Python that listens for a new upload event to a specific Google Cloud Storage bucket. Next, the script will take that image and pass it to the Google Cloud Vision API, capture the results, and append them to a table in BigQuery for further analysis. This example will use sample images but can be modified to read documents containing text. Cloud Functions can be a good choice for short-lived requests that do one specific task in response to another event. Note that Cloud Functions has a few limitations, such as a nine-minute execution limit. You can write functions in the Google Cloud Platform console or write them locally and deploy using Google Cloud tooling on your local machine. This is especially useful when you want to focus on writing code but don’t want to worry about the underlying infrastructure. Cloud Functions can be invoked from several events, such as HTTP, Cloud Storage, Cloud Pub/Sub, Cloud Firestore, Firebase, and in response to Google Cloud Logging events. With Cloud Functions, monitoring, logging, and debugging are all integrated, and functions scale up and down as required. Cloud Functions scales as needed and integrates with Google Cloud’s operations suite (such as Cloud Logging) out of the box.įunctions are useful when you have a task or series of tasks that need to happen in response to an event. Why Use Google Cloud Functions? Google Cloud Functions is a Function as a Service (FaaS) that allows engineers and developers to run code without worrying about server management.
