Cloud Native

Chapter 1. Introduction to Cloud Native

What are cloud native applications? What makes them so appealing that the cloud native model is now considered not only for the cloud, but also for the edge? And, finally, how do you design and develop cloud native applications? These are all questions that will be answered throughout this book. But before we dive into the details on the what, why, and how, we want to provide a brief introduction to the cloud native world and some of the fundamental concepts and assumptions that are building the foundation for modern cloud native applications and environments.

Distributed Systems

One of the biggest hurdles that developers face when they build cloud native applications for the first time is that they must deal with services that are not on the same machine, and they need to deal with patterns that consider a network between the machines. Without even knowing it, they have entered the world of distributed systems. A distributed system is a system in which individual computers are connected through a network and appear as a single computer. Being able to distribute computing power across a bunch of machines is a great way to accomplish scalability, reliability, and better economics. For example, most cloud providers are using cheaper commodity hardware and solving common problems such as high availability and reliability through software-based solutions.
