An Introduction to Cloud Development and Engineering

A full introduction to the world of cloud development.

About the Book

An Introduction to Cloud Development gives a very simple introduction to all the core concepts used by teams moving their monolithic applications to a cloud-native solution.

We'll be following along the story of how Gemma managed to transform a fictional online comic-book store from a monolithic application to a series of cloud-ready microservices that utilize a number of industry standard tools such as EC2, Load Balancers, Docker and more.

Causes Supported

Electronic Frontier Foundation

Defending your civil liberties in a digital world.

Based in San Francisco, EFF is a donor-supported membership organization working to protect fundamental rights regardless of technology.

From the Internet to the iPod, technologies are transforming our society and empowering us as speakers, citizens, creators, and consumers. When our freedoms in the networked world come under attack, the Electronic Frontier Foundation (EFF) is the first line of defense. EFF broke new ground when it was founded in 1990—well before the Internet was on most people's radar—and continues to confront cutting-edge issues defending free speech, privacy, innovation, and consumer rights today. From the beginning, EFF has championed the public interest in every critical battle affecting digital rights.
