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.

Application Centric Design (CNMM Axis-2)


As discussed in the previous chapter, creating serverless and microservice-based applications is a key cloud native way to differentiate as compared to pre-cloud era design patterns. So, let's look at how can we design such applications in Microsoft Azure cloud using multiple key services.

Serverless microservice

In this section, we are going to create a serverless microservice application on Microsoft Azure. In order for you to easily compare and learn capabilities across cloud providers, we will use the same example of creating a Weather Services application, which we discussed in the previous chapter on AWS. So, as a refresher, the overall application will have three main parts:

  • An API trigger to invoke the application.
  • A function that is written in Azure Functions.
  • An external weather service to which we will pass some parameters and get results:
