Overview of this book

Google Cloud Platform is one of the three major cloud providers in the industry, exhibiting great leadership in application modernization and data management. This book provides a comprehensive introduction for those who are new to cloud development and shows you how to use the tools to create cloud-native applications by integrating the technologies used by Google. The book starts by taking you through the basic programming concepts and security fundamentals necessary for developing in Google Cloud. You'll then discover best practices for developing and deploying applications in the cloud using different components offered by Google Cloud Platform such as Cloud Functions, Google App Engine, Cloud Run, and other GCP technologies. As you advance, you'll learn the basics of cloud storage and choosing the best options for storing different kinds of data as well as understand what site reliability engineers do. In the last part, you'll work on a sample case study of Hip Local, a community application designed to facilitate communication between people nearby, created by the Google Cloud team. By the end of this guide, you'll have learned how to design, develop, and deploy an end-to-end application on the Google Cloud Platform.

Cloud monitoring SLOs

If you have an externally consumed application and you would like to better measure your customer satisfaction based on the quality of your service, this is possible by creating service-level objectives, or SLOs.

For this, we can create a specific group of alerts that focus on important metrics for our clients. Some recommendations for identifying good SLOs include the following:

  • Identify flows within the application that are critical and that directly impact the business (for example, product payment).
  • Identify metrics within the application that can determine the user experience and be used as service-level indicators, or SLIs (for example, the latency of operations in our application must be less than 100 ms per action).
  • Determine the objectives to be met for our SLOs and how they will be measured (for example, the % of operations with latency under...
