10 | **Design high-availability and cost-effective applications for the cloud**
11 |
12 | ## What is this book about?
13 | 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.
14 |
15 | This book covers the following exciting features:
16 | * Learn the difference between cloud native and traditional architecture
17 | * Explore the aspects of migration, when and why to use it
18 | * Identify the elements to consider when selecting a technology for your architecture
19 | * Automate security controls and configuration management
20 | * Use infrastructure as code and CICD pipelines to run environments in a sustainable manner

27 | ## Instructions and Navigations
28 | All of the code is organized into folders. For example, Chapter02.
29 |
30 | The code will look like the following:
31 | ```
32 | print('Loading function')
33 |
34 | def respond(err, res=None):
35 | return {
36 | 'statusCode': '400' if err else '200',
37 | 'body': err if err else res,
38 | 'headers': {
39 | 'Content-Type': 'application/json',
40 | },
41 | }
42 | ```
43 |
44 | **Following is what you need for this book:**
45 | Cloud Native Architectures is for software architects who are keen on designing resilient, scalable, and highly available applications that are native to the cloud.
