Amazon Web Services are a comprehensive set of services that help you build and deploy better software. There are over 25 data centers hosting more than 1.4 million servers. This vast computing power is used to host services as diverse as on-demand computation, file storage, databases, application services and infrastructure management. In fact, there are so many services that it can be difficult to keep track of them all or to know if a particular one might be of use.

In this course, Tuts+ instructor Markus Mühlberger will show you 10 services that you should be aware of if you do web application development or operations. One or more of these popular services might just come in handy for your future projects, professional or personal.

1. Introduction

1.1 Introduction

Hi, my name is Markus Muhlberger, and welcome to the Explore Amazon Web Services course. Amazon Web Services or AWS, are a comprehensive set of services that help you build better software. There are over ten regions and over 25 data centers hosting over 1.4 million servers. This vast computing power is used to provide services from computation to file storage, databases, application services, infrastructure management and much more. In this course, we are going to look at ten different services that you should know about if you do any developing of web applications or applications that are computation intensive in general. Those services include the very popular Easy two, and S three, as well as Landa, SQS, DynamoDB, and route 53 sounds exciting? It is, let's get started at the first lesson. See you there.

1.2 AWS Console Overview

Hi, welcome to the first lesson of Explore Amazon Web Services. In this lesson, we will take a look at the AWS console, your main interface to all those services. As you can see, AWS offers a lot of different tools. The main categories are compute, data storage, data basis, and applications. But there are also tools for developers and infrastructure managers, as well as some for mobile applications. When you look at the top right, you can see the major way of organization in AWS. Each service you use is provided in a region. With a few exceptions, of course. Those are groups of AWS data centers, which host all those services. Right now, it is set to Oregon. But at the moment, there are two more in the US, two in Europe, three in Asia, and one in South America. Not all services are available in all regions. For instance, the Developer tools are only available in three of them. Another thing you might notice is that the console directly connects to the data center. So when you are using one third the way, it will take significantly longer to load lists and perform actions. I'm going to switch to Sydney, and you will see what I mean in a moment. Let us take a look at a service right now. EC2, for instance. Whenever you go to a service, you see a dashboard that tells you what is running in this specific region. This is important, since those regions are completely independent. Let's just quickly create a simple instance. You will learn more about EC2 in a later lesson. So don't worry if you don't get everything right now. You see, we now have an instance running, or initializing rather. When we switch back to Oregon, you can see that this instance isn't listed anymore. The next thing to notice is the tug bar. Since there are so many services, and you are probably only using a few of them frequently, you can use it as a quick bar. By clicking edit, you can drag and drop services onto the drop bar, and those link directly to the dashboards. When we go S3, you can see the exception of the region rule. In the top right, the region changed to global. It isn't that S3 doesn't get stored in regions, it's just that the management interface doesn't defer here, but only when you create the bucket. The last thing I wanted to show you are your account settings. You can see there is a lot of sensitive data, so I'm not going to poke around very much here. But everything related to billing and payment is to be set in this area of the console. Also, even though AWS still provides an interface to the old security credentials system, it is outdated, and you are recommended to use identity and access management instead. You will be notified about this every time you visit the site. And this is exactly what we are going to learn in the next lesson, IAM, Identity and Access Management. See you there.
