Building Serverless Web Applications. Develop scalable web apps using the Serverless Framework on AWS

Diego Zanon

This book will equip you with the knowledge needed to build your own serverless apps by showing you how to set up different services while making your application scalable, highly available, and efficient.We begin by giving you an idea of what it means to go serverless, exploring the pros and cons of the serverless model and its use cases. Next, you will be introduced to the AWS services that will be used throughout the book, how to estimate costs, and how to set up and use the Serverless Framework.From here, you will start to build an entire serverless project of an online store, beginning with a React SPA frontend hosted on AWS followed by a serverless backend with API Gateway and Lambda functions. You will also learn to access data from a SimpleDB database, secure the application with authentication and authorization, and implement serverless notifications for browsers using AWS IoT. This book will describe how to monitor the performance, efficiency, and errors of your apps and conclude by teaching you how to test and deploy your applications.

Building Smart Home Automation Solutions with Home Assistant. Configure, integrate, and manage hardware and software systems to automate your home

Marco Carvalho

Picture a home where you can adjust the lighting based on the time of day or when movement is detected. In this same home, you can also detect when a door is unexpectedly opened or an alarm is triggered in response to any suspicious activity. Such automated devices form part of a smart home, and the exciting part is that this book teaches you how to create and manage these devices all by yourself.This book helps you create your own ecosystem to automate your home using Home Assistant software. You’ll begin by understanding the components of a home automation system and learn how to create, hack, and configure them to operate seamlessly. Then, you'll set up Home Assistant on a Raspberry Pi to work as a home automation server, build your own IoT sensors based on ESP32/ESP8266, and set up real-life automation use cases using hands-on examples and projects. The chapters will also guide you in using software tools such as Node-RED, InfluxDB, and Grafana to manage, present, and use data collected from your Home Automation devices. Finally, you’ll gain insights into new technologies and trends in the home automation space to help you continue with your learning journey.By the end of this book, you’ll be able to build your own creative, IoT-based home automation system using different hardware and software technologies.
