Cloud Native Architectures

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.

Procurement in the cloud

One of the reasons that the cloud is so popular, and that cloud native architectures are becoming the normal method of designing workloads, is due to the procurement and consumption model used. The easy way to think about this is the ability to procure using operational expenditure (OpEx) instead of the traditional capital expenditure (CapEx), which can have a large impact on the way a company handles revenues, taxes, and long-term depreciation of assets. However, that is just the surface of the impact that the cloud has on the way organizations procure their IT resources.

The shift to pay per use consumption by cloud vendors has enabled ISVs to also align their business model, making their products easier to consume alongside the chosen cloud vendor services. This change can have a significant impact on the way that organizations negotiate contracts with ISVs, often lowering their overall bill by only paying for what they used instead of long-term contracts based...
