Introduction

Studying for any certification always involves deciding how much of your studying should be practical hands-on experience and how much should be simply memorizing facts and figures. Between the two of us, we've taken more than 20 different IT certification exams, so we know how important it is to use your study time wisely. We've designed this book to help you discover your strengths and weaknesses on the AWS platform so that you can focus your efforts properly. Whether you've been working with AWS for a long time or you're relatively new to it, we encourage you to carefully read this book from cover to cover.

Passing the AWS Certified Cloud Practitioner exam won't require you to know how to provision and launch complex, multitier cloud deployments. But you will need to be broadly familiar with the workings of a wide range of AWS services. Everything you'll have to know should be available in this book, but you may sometimes find yourself curious about finer details. Feel free to take advantage of Amazon's official documentation, which is generally available in HTML, PDF, and Kindle formats.

Even though the AWS Certified Cloud Practitioner Study Guide: CLF-C02 Exam skews a bit more to the theoretical side than other AWS certifications, there's still a great deal of value in working through each chapter's hands-on exercises. The exercises here aren't meant to turn you into a solutions architect who knows how things work but to help you understand why they're so important.

Bear in mind that some of the exercises and figures rely on the AWS Management Console, which is in constant flux. As such, screenshots and step-by-step details of exercises may change. If what you see in the Management Console doesn't match the way it's described in this book, use it as an opportunity to dig into the AWS online documentation or experiment on your own.

Each chapter includes review questions to thoroughly test your understanding of the services you've seen. We've designed the questions to help you realistically gauge your understanding and readiness for the exam. Although the difficulty level will vary between questions, you can be sure there's no "fluff." Once you complete a chapter's review questions, refer to Appendix A for the correct answers and detailed explanations.

The book also comes with a self-assessment exam at the beginning with 25 questions, two practice exams with a total of 100 questions, and flashcards to help you learn and retain key facts needed to prepare for the exam.

Changes to AWS services happen frequently, so you can expect that some information in this book might fall behind over time. To help you keep up, we've created a place where we'll announce relevant updates and where you can also let us know of issues you encounter.

What Does This Book Cover?

This book covers topics you need to know to prepare for the Amazon Web Services (AWS) Certified Cloud Practitioner exam:

• Chapter 1: The Cloud This chapter describes the core features of a cloud environment that distinguish it from traditional data center operations. It discusses how cloud platforms provide greater availability, scalability, and elasticity and what role technologies such as virtualization and automated, metered billing play.
• Chapter 2: Understanding Your AWS Account In this chapter, you'll learn about AWS billing structures, planning and monitoring your deployment costs, and how you can use the Free Tier for a full year to try nearly any AWS service in real-world operations for little or no cost.
• Chapter 3: Getting Support on AWS This chapter is focused on where to find support with a problem that needs solving or when you're trying to choose between complex options. You'll learn about what's available under the free Basic Support plan as opposed to the Developer, Business, and Enterprise levels.
• Chapter 4: Understanding the AWS Environment In this chapter, we discuss how to enhance security and availability, and how Amazon organizes its resources in geographic regions and availability zones. You'll also learn about Amazon's global network of edge locations built to provide superior network performance for your applications.
• Chapter 5: Securing Your AWS Resources The focus of this chapter is security. You'll learn how you control access to your AWS-based resources through identities, authentication, and roles. You'll also learn about data encryption and how AWS can simplify your regulatory compliance.
• Chapter 6: Working with Your AWS Resources How will your team access AWS resources so they can effectively manage them? This chapter will introduce you to the AWS Management Console, the AWS Command-Line Interface, software development kits, and various infrastructure monitoring tools.
• Chapter 7: The Core Compute Services Providing an alternative to traditional physical compute services is a cornerstone of cloud computing. This chapter discusses Amazon's Elastic Compute Cloud (EC2), Lightsail, and Elastic Beanstalk services. We also take a quick look at various serverless workload models.
• Chapter 8: The Core Storage Services This chapter explores Amazon's object storage services including Simple Storage Service (S3) and Glacier for inexpensive and highly accessible storage, and Storage Gateway and Snowball for integration with your local resources.
• Chapter 9: The Core Database Services Here you will learn about how data is managed at scale on AWS, exploring the SQL-compatible Relational Database Service (RDS), the NoSQL DynamoDB platform, and Redshift for data warehousing.
• Chapter 10: The Core Networking Services AWS lets you control network access to your resources through virtual private clouds (VPCs), virtual private networks (VPNs), DNS routing through the Route 53 service, and network caching via CloudFront. This chapter focuses on all of them.
• Chapter 11: Automating Your AWS Workloads This chapter covers the AWS services designed to permit automated deployments and close DevOps integration connecting your development processes with your Amazon-based application environments.
• Chapter 12: Common Use-Case Scenarios This chapter illustrates some real-world, cloud-optimized deployment architectures to give you an idea of the kinds of application environments you can build on AWS.
• Appendix A: Answers to Review Questions This appendix provides the answers and brief explanations for the questions at the end of each chapter.
• Appendix B: Additional Services To make sure you're at least familiar with the full scope of AWS infrastructure, this appendix provides brief introductions to many of the services not mentioned directly in the chapters of this book.
