Cloud Native Architectures

By: Tom Laszewski, Kamal Arora, Erik Farr, Piyum Zonooz

Overview of this book

Cloud computing has proven to be the most revolutionary IT development since virtualization. Cloud native architectures give you the benefit of more flexibility over legacy systems. To harness this, businesses need to refresh their development models and architectures when they find they don’t port to the cloud. Cloud Native Architectures demonstrates three essential components of deploying modern cloud native architectures: organizational transformation, deployment modernization, and cloud native architecture patterns. This book starts with a quick introduction to cloud native architectures that are used as a base to define and explain what cloud native architecture is and is not. You will learn what a cloud adoption framework looks like and develop cloud native architectures using microservices and serverless computing as design principles. You’ll then explore the major pillars of cloud native design including scalability, cost optimization, security, and ways to achieve operational excellence. In the concluding chapters, you will also learn about various public cloud architectures ranging from AWS and Azure to the Google Cloud Platform. By the end of this book, you will have learned the techniques to adopt cloud native architectures that meet your business requirements. You will also understand the future trends and expectations of cloud providers.

Self-healing infrastructures

Another important paradigm to adopt for cloud-native applications as it relates to scalability and availability are self-healing infrastructures. A self-healing infrastructure is an inherently smart deployment that is automated to respond to known and common failures. Depending on the failure, the architecture is inherently resilient and takes appropriate measures to remediate the error.

The self-healing aspect can apply at the application, system, and hardware levels. The cloud has completely taken responsibility for "hardware self-healing". No such thing technically exists, as we have yet to figure out a way to repair broken hard disks, torched CPUs, or to replace burned-out RAM without human interaction. As cloud consumers, however, the current state of affairs mimics an idealistic future. CSPs deploy people behind the scenes to repair and replace failing hardware resources quickly and furtively. By our strict definition, we have yet to approach self-healing...
