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.

What are cloud native architectures?

If you asked 100 people what the definition of cloud native was, you just might get 100 different answers. Why are there so many different answers? To start with, cloud computing itself is still evolving every day, so the definitions offered a few years ago are quite possibly not fully up to date with the current state of the cloud. Secondly, cloud native architectures are a completely new paradigm that use new methods to solve business problems that can typically only be achieved at the scale of cloud computing. Finally, depending on the role of the person being asked, the definition is very different, whether they be an architect, developer, administrator, or decision maker. So, what exactly is the definition of cloud native?

Let's start with a generally accepted definition of what cloud computing is according to AWS: 

"Cloud computing is the on-demand delivery of compute power, database storage, applications, and other IT resources through a cloud services platform via the internet with pay-as-you-go pricing."

Therefore, at its most basic form, cloud native means to embrace cloud computing services to design the solution; however, that only covers part of what is required to become cloud native. There is a lot more than just using the underlying cloud infrastructure, even if it's the most mature service available. 

Automation and application design play significant roles in this process as well. The cloud, with its API-driven design, allows for extreme automation at scale to not only create instances or specific systems, but to also completely roll out an entire corporate landscape with no human interaction. Finally, a critical component in creating a cloud native architecture is the approach used to design a specific application. Systems designed with the best cloud services, and deployed with extreme automation, can still fail to achieve desired results if the logic of the application does not take into consideration the new scale at which it can operate.
