Skill Level Beginner
- Before we start getting into the real details of this chapter, I want to take a moment to talk to you about the AWS specialty exam for the database professional and some of the recommended knowledge that they suggest you have and why we're helping you get some of that knowledge right here at the beginning of this course. So what I'm going to do is take you into the objectives to help you see what you might want to be thinking about as far as existing knowledge and where you might even go to get some of that knowledge, if you lack in those areas. So first of all, you'll notice in the actual exam blueprint or objectives document, whatever you prefer to call this exam guide that AWS provides for the database specialty, you'll notice they have a section "Recommended AWS Knowledge". Now I find it interesting that they say "Recommended AWS Knowledge" and then the very first bullet point says a minimum of five years of experience with common database technologies, which is not AWS knowledge. So it's a bit of a confusing thing at first but what they're trying to help you understand is that you need to understand databases in general. That is to say, they're not going to, in this exam guide, explicitly list understand a relational database versus a NoSQL database versus a time series database, but they do expect that you understand what they generally are. So here in chapter one and in chapter two, I'll be helping you to understand generally databases in chapter one. And then in chapter two, specifically as we talk about each AWS database, like a time series database, I'll tell you what that kind of database actually is and why you would use it. So filling in those gaps of knowledge that you might have. Now the other thing that you'll see here is it says you need at least two years of hands-on experience working with AWS. Well, you don't really have to have two years of hands-on experience. You need to know the things you'd have if you had two years of hands-on experience. For example, I'll talk about EC2 instances, but I don't really explain in detail what those are. And so it's kind of expected that you understand what an EC2 instance is and how you might go about creating one and things like that. Now the good news is we have other courses on AWS that do give you that fundamental knowledge for working with AWS. However, if you don't have the experience and you want to dive right into this course, then here's what I suggest. Go create a free AWS account and then play around with some of the different settings and configuration options and things that you can do in there. And that'll get you some experience working with things like EC2 instances and virtual private clouds and the different things that really the database systems need as well but this particular certification doesn't go into detail on those. So you have a couple of options, go to our other AWS Architect-Associate course, you can get the knowledge there. Or you can go into a free AWS account and just start playing with the tools, see what it can do and learn about it there. And then as you're going through this course, if you encounter something you don't know about, you can go into that free account and you can learn more about those concepts in that way. So there are a couple of options there for you to help you get started. Now, additionally in this exam guide, you'll see if you go down further that it tells you a little bit about the exam content, multiple choice, multiple response questions. It tells you when you can expect to get results for your exam, and then it gives you the actual knowledge domains, the different areas that you need to know to be prepared for this exam and they include workload-specific database design, deployment and migration, management and operations, monitoring and troubleshooting and database security. And of course, we're going to be going through all of that right here in this course. So I hope this information helps you to understand a little bit about what you need to know in order to get started with this course and to understand everything that we talked about. I will ease you into it right here in the first chapter as we get an overview of database technologies in general.
