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.

Before the cloud


Before we can discuss the cost of building cloud native applications, we need to turn back the clock to examine infrastructure before the cloud, namely on-premises systems. When an enterprise deems it necessary to establish or expand its IT infrastructure, a number of actions have to be taken regarding:

  • Physical space: Finding space in the existing data center or buying/renting new space for the data center buildout.
  • Electric power: This can be easily overlooked. Deploying a large scale array of servers requires large power conduits that may not exist in a new location or be available in the current space. In addition, redundancy and backup power generators are often required to continue critical operations in case of a power outage or disaster.
  • Physical Security: Paramount in enterprise deployments, establishing physical security to the hardware supporting a data center requires key/badged access points, security personnel, cameras, and security equipment.
  • Network connectivity...
