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.

Cloud native security patterns


Now that we have a broad understanding of the native security tools available to us in the cloud, we can dive into some examples of how to design and build common deployments. It is important to realize that each use case will not leverage all security tools and will not exactly match other security patterns. We aim to demonstrate a palette of different approaches to varying problems and give the reader the ability to select and combine different solutions.

As our first example, let's consider a three-tier web application:

Figure 6.3

Security groups should be used to separate tiers within a stack, as shown in the previous diagram of a three-tier web application. Each tier has its own security group, which has unique rules that expose minimal attack vectors.

For our first security pattern example, let's use a basic three-tier web application. The 3 tiers comprising this pattern are the web, application, and database. A user routing from the internet will not directly...
