Engineer – Professional: Evaluates the ability of the test taker to perform DevOps (that is, create an interface between developers and other IT professionals). This means having some level of skill in both administration and development. In addition, the candidate must have knowledge of processes that enable smooth design, development, deployment, management, and operation of applications.
Locating certification resources
You can find all sorts of interesting aids online for getting your certification. However, the best place to start is directly on the Amazon website. Unfortunately, the information you find isn’t the best organized at times. Start by ensuring that you meet the requirements in the Candidate Overview section. Until you meet those requirements, it isn’t particularly useful to move forward (unless you want to end up with a paper certification – one that doesn’t actually mean anything).
After you have fulfilled the minimum requirements, download the Exam Guide. The guide tells you that you need to be proficient in a number of areas in order to pass, which shouldn’t surprise you. AWS wants to ensure that you actually know the material. Fortunately, you can also find online sources to help you make sense of the Exam Guide. For example, there is an excellent video on the requirements for the AWS Certified SysOps Administrator – Associate exam at https://www.youtube.com/watch?v=JCkD8lpadj8. Watching the video and going through the Exam Guide can help you get a better idea of what you need to do.
At some point, you want to download the example questions. However, given that AWS provides only one set of example questions and that those precise questions are unlikely to appear on the exam, memorizing them won’t do you any good. What you need to do is study and when you feel you’re ready, try the example questions, which can help you determine your weak areas. Unfortunately, there are only a few example questions – not enough to give you a good feel for the exam.
Every certification also comes with a Take a Practice Exam option. Be sure to save this feature for last. Again, you don’t get many questions, the questions don’t change, and they’re not likely to appear on the exam in the precise form you see them. The purpose of the practice exam is to help you sense whether you’re ready.
As you go through the book, make sure to also look at the Getting Started and FAQs for each of the services covered. These two sources of information contain a great deal of information that Amazon is likely to use for exam questions. You don’t have to memorize the material, but being familiar with it gives you a definite advantage.
Obtaining a certification helps you prove your level of proficiency to someone else, which is one level of the education process. In many cases, you can skip this level unless you have specific needs that a certification can address. However, you must continue to build on your expertise. Simply learning the basics and then never cracking a book again will result in your eventual termination as an administrator because computer technology continues to change. In short, education is continuous when you’re an administrator. Getting a well-rounded education is essential, as is continuing to learn more whenever you can and in whatever way that you can. Even dibs and dabs of time spent learning can make a big difference.

Chapter 2
Obtaining Free Amazon Services
IN THIS CHAPTER
❯❯ Considering the free service offerings
❯❯ Ensuring that you have the right hardware
❯❯ Ensuring that you have the right networking setup
❯❯ Getting your free account
❯❯ Using your free account for the first time
One of the purposes of this book is to help you discover a lot more about Amazon Web Services (AWS) through experimentation. Of course, Amazon would just love to have you buy these services, but a free option, which is the focus of this chapter, is also available. The issue is one of figuring out just what Amazon means by free. This chapter’s first section clears up the questions you might have about what free means, because some services are always free and others are free for a limited time. In addition, you must consider the limits of free. If you use some of these services too much, you end up paying for them. Therefore, you need to know the rules in order to get the services free.
The next two sections of the chapter consider hardware and network requirements. Note that Amazon likes you to have both Linux and Windows knowledge when you take your certification exams (see the “Understanding the AWS Certifications” section of Chapter 1), and such knowledge
