Overview of this book

Google Cloud Platform is a cloud computing platform that offers products and services to host applications using state-of-the art infrastructure and technology. You can build and host applications and websites, store data, and analyze data on Google's scalable infrastructure. This book follows a recipe-based approach, giving you hands-on experience to make the most of Google Cloud services. This book starts with practical recipes that explain how to utilize Google Cloud's common services. Then, you'll see how to make full use of Google Cloud components such as networking, security, management, and developer tools. Next, we'll deep dive into implementing core Google Cloud services into your organization, with practical recipes on App Engine, Compute Engine, Cloud Functions, virtual networks, and Cloud Storage. Later, we'll provide recipes on implementing authentication and security, Cloud APIs, command-line management, deployment management, and the Cloud SDK. Finally, we'll cover administration and troubleshooting tasks on applications with Compute services and we'll show how to monitor your organization's efficiency with best practices.

Image resizing using Google Cloud Storage and Cloud Functions


Google Storage is extensively used to store static images to be served by different platforms. One of the needs of the modern-day digital world is to have images created for different form factors—desktop, mobile and tablet screens. In this recipe, we'll develop a Cloud Function to resize the images uploaded to a bucket:

Getting ready

The following are the initial setup verification steps to be carried out before the recipe can be executed:

  1. Create or select a GCP project
  2. Enable billing and enable the default APIs (some APIs such as BigQuery, storage, monitoring, and a few others are enabled automatically)
  3. Verify that Node.js and Google Cloud SDK are installed
  4. Verify that the Google Cloud Functions API is enabled

How to do it...

The steps involved are as follows:

  1. Navigate to the Chapter02/imageresize folder. 
  2. The package.json file contains the necessary models for our Node.js Cloud Function.
  3. The config.json file contains the dimensions for...
