For our customers (whom we are always obsessing over). May this book find you well in your pursuit of becoming an AWS Certifi ed Systems Operator.

Acknowledgments

The authors would like to thank a few people who helped us develop and write the AWS Certified SysOps Administrator Official Study Guide – Associate Exam.

First and foremost, a very big thank you to all of our friends and families who put up with us spending weekends, evenings, and vacations creating content, writing questions, and reviewing each other’s chapters. Their flexibility, patience, and support made this book a reality.

Thank you to Nathan Bower and Victoria Steidel, the technical writers at AWS who reviewed and edited every single piece of content. They were always willing to review content, and their due diligence kept us on schedule. Their wisdom made us all better writers.

We could not have written this book without the help of our friends at Wiley. Gary Schwartz, Project Editor, provided valuable advice that kept us on track with our deliverables. Additionally, we were guided by Kezia Endsley, Copy Editor, who further refined our content to make the various chapters written by the many authors, flow into one cohesive piece of work.

A special thanks to Eli Schilling, Biff (yes that’s his real name) Gaut, and Brian Wagner. Eli gathered the group of authors to write this book, Biff provided us much needed foresight, as he had co-authored the AWS Certified Solutions Architect Official Study Guide, and Brian helped us write some last-minute questions for the online practice exams.

Lastly, we want to thank all the Solutions Architects and Technical Trainers at AWS who participated in certification blueprint development, question writing, review sessions, and the development of a world-class certification program for cloud practitioners that is setting the standard for our industry. #LearnAndBeCurious

Foreword

I entered college in 1978, and I immediately found a second home at the computer lab on campus. This lab was home to an IBM mainframe and a roomful of noisy keypunch machines. I punched my code onto a stack of cards, and I handed the stack to a system operator. The operator loaded the cards into the reader, and my job was queued for processing. If things went well and the mainframe was not too busy, I would have my cards and my output back within four hours or so. The operator managed the work queue for the mainframe, adjusting the balance of jobs and priorities, looking for hot spots and slowdowns, and keeping the monolithic mainframe as busy and as productive as possible at all times.

As a young, curious student, I always wondered what was happening behind the scenes. As a young, impoverished student, in the days before the Internet, information was not always easy to come by. I found a rack of manuals in the lab, figured out how to order others for free, and even scavenged the trash cans for operating system “builds” to study. That thirst for knowledge, with a focus on understanding how things work at the most fundamental level, has worked really well for me over the intervening four decades.

A little over a decade ago, I wrote blog posts to announce the launches of Amazon Simple Storage Service (Amazon S3) and Amazon Elastic Compute Cloud (Amazon EC2). Those early launches set the tone for what was to come, introducing services that emerged with a minimal feature set that would be enhanced over time in response to customer feedback. At that time, aspiring AWS developers and architects did not need to make very many choices when they set out to build an AWS-powered system. There was one instance type, a couple of Availability Zones in a single Region, and simple access via the AWS CLI and the API.

Back in my mainframe days, operations was a hands-on affair. There was little in the way of tooling or automation; the operator was expected to watch the console, check on status, and to deal with issues as they arose. Today, many routine operations are handled automatically. Fault tolerance, automatic scaling, load balancing, and other high-level facilities take on many chores that were once described in detailed run books. With this change, systems operations comes into play much earlier in the system-building process, with the goal of setting up the system for success and high availability. At the same time, the operations role now spans a wider range of tasks and technologies including networking, security, and optimization. With pay-as-you-go services now the norm, people who once focused on technology can now add business skills to their repertoire.

If you are about to read this book, I am sure that you know that AWS is far more complex than it was a decade ago. On the Amazon EC2 side alone, there are now dozens of instance types, multiple types of Amazon Elastic Block Storage (Amazon EBS) volumes, and far more moving parts. There are now close to 100 services, each of which can be a valuable addition to your toolbox. The vocabulary itself has changed, with new terms such as containers, microservices, serverless computing, infrastructure as code, and so forth now commonplace.

You now face many choices when you set out to design and implement a new system. This book is designed to provide you with detailed information on many aspects of AWS, coupled with the practical knowledge needed to put your new knowledge to use and to earn your AWS certification. Within its chapters, you will find service overviews, sample scenarios, test-taking tips, and exercises. After setting up your AWS tools, you will learn about security, compute services, storage services, networking, databases, and more. Towards the end of the book, you will wrap up by learning about monitoring, metrics, and high availability. As you will soon see, the authors have packed it with the insights that they have gained while putting AWS to use in a wide variety of customer environments. There are no better teachers than those who have actually put their theory into practice.

You can choose to study the chapters individually, or you can digest the entire book as-written. Either way, I know that you will be well-prepared to build great systems and to pass your certification exams. I strongly encourage you to get hands-on experience with each service by working through the scenarios and the exercises.

I believe in the principle of life-long learning, especially when it comes to technology. The half-life of knowledge is shorter than ever before, and keeping up is far better than catching up. So dive deep and keep on learning!

— Jeff Barr, Chief Evangelist, AWS

Introduction

Preparing to take and pass any certification is a studious process. The AWS Certified SysOps Administrator Official Study Guide - Associate Exam was written to align with the exam blueprint to enable you to study for the exam, perform exercises, and answer review questions to enable you to become a skilled systems operator on the AWS cloud and to take and pass the AWS Certified SysOps Administrator – Associate exam with confidence.

This study guide presents the set of topics needed to round out a systems operator/systems administrator’s hands-on experiences with AWS by covering the relevant AWS cloud services and concepts within the scope of the AWS Certified SysOps Administrator – Associate exam. This study guide begins with an introduction to Systems Operations on AWS, which is then followed by chapters on specific domains covered in the exam. In addition to the material covered on the exam, the chapters go deep into the actual technology. The authors go deep on topics that will serve you in preparing for the exam and the book should make a good desktop reference on AWS systems operations.

Each chapter includes specific information on the service or topic covered, followed by an Exam Essentials section that contains key information needed in your exam preparation. The Exam Essentials section is followed by a Test Taking Tip to help you prepare for what you will experience on the exam or at the testing center.

Next, each chapter includes an Exercise section with activities designed to help reinforce the topic of the chapter with hands-on learning. Each chapter then contains sample Review Questions to get you accustomed to answering questions about how to use and administer AWS cloud services.

Following this up-front section, the book contains a self-assessment exam with 25 questions. Two practice exams with 50 questions each are also available to help you gauge your readiness to take the exam, and flashcards are provided to help you learn and retain key facts needed to prepare for the exam.

If you are looking for a targeted book, created by technical trainers and solutions architects who wrote, reviewed, and developed the AWS Certified SysOps Administrator – Associate exam, then this is the book for you.
