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.

Security at every layer

There is no shortage of options when it comes to what firewall and VPN appliances are available for data centers or cloud environments. The important factor when it comes to choosing them isn't necessarily the security product, but the given deployment and the features available (including access controls, authentication, and authorization ability). Ensuring these are built into the application layer rather than relying solely on network security is critical. An application-level security implementation makes access control scalable, portable, and immutable. Access can then be governed based on the real identity of an application or (micro)service rather than on human provisioning.

By our definition, a cloud native application is a secured application. A secured system by logical extension must be a reliable system. Application code is packaged and deployed across multiple cloud regions; executed in various containers; and is accessed by many clients or other applications...
