Overview of this book

Serverless applications are becoming very popular among developers and are generating a buzz in the tech market. Many organizations struggle with the effective implementation of DevOps with serverless applications. DevOps for Serverless Applications takes you through different DevOps-related scenarios to give you a solid foundation in serverless deployment. You will start by understanding the concepts of serverless architecture and development, and why they are important. Then, you will get to grips with the DevOps ideology and gain an understanding of how it fits into the Serverless Framework. You'll cover deployment framework building and deployment with CI and CD pipelines for serverless applications. You will also explore log management and issue reporting in the serverless environment. In the concluding chapters, you will learn important security tips and best practices for secure pipeline management. By the end of this book, you will be in a position to effectively build a complete CI and CD delivery pipeline with log management for serverless applications.

The module will be loaded using a require() call. So, functions are contained within an index.js file. We can invoke the function from HTTP request methods such as GET, POST, PUT, OPTIONS, and DELETE. The deployment can be done through a command-line tool provided by Google Cloud CLI, through the cloud function UI on a GCP console, and can also be done through a serverless framework. We will be looking into each way throughout this chapter. The deployable is a ZIP file, which has functions packaged into it, and it is deployed...
