An Introduction to Cloud Development and Engineering
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.
