Initialize the AWS Application Migration Service

“

- [Instructor] Before we can use the application migration service, we have to initialize it. Now, the important thing to know about the initialization process is that it is region specific. So you have to initialize the application migration service within the region where you're going to be working. If you're going to be using multiple regions, then you'll have to initialize each one of those regions individually. The good news is that the initialization process is more or less effortless. So let's take a look at how this works. I'm going to go ahead and select a region. And for my region, I'm going to go with Northern Virginia, US East one. So I've changed regions and you can see the region listed right here. Now, I'm going to open up the application migration service. So I'm going to click on this icon up here. Next, I'm going to select migration and transfer. And then I'm going to click on the AWS Application Migration Service. And so this opens up the application migration service and I'm going to click on Get Started. And now I see a prompt telling me that I need to initialize the service. And if you look at the text, it says, in order to use application migration service in this region, the service must first be initialized by an admin user of the AWS account. Once the service is initialized, you can modify the default service templates on the settings page. By continuing, you are allowing application migration service to create all the IAM roles required to facilitate data replication and the launching of migrated servers. So what this is essentially saying is that if we continue, then there are going to be some IEM roles that are created in the background as a way of facilitating the migration process. So I'm going to go ahead and click on set up service. And so now after a few seconds, we see a message saying that the default templates were created. I'll go ahead and close that out. We'll be taking a look at those templates in some of the later videos. And I've also got a message saying that there are no default subnets defined in the system and that application migration service has selected a subnet to use as the default. And again, that's something that we're going to be doing in one of the later videos. So at this point, the service is initialized. Now as you'll recall, we saw a message saying that when we initialize the service, there are going to be some IAM roles that are created. So let's go ahead and take a look at what those roles are. So I'm going to go ahead and open up IAM. And there are several different roles that have been created. The first one is called AWS Service for Application Migration Service. And if we click on roles and we have a number of different roles that were created. So the first thing that I'm going to do is type AWS service. And here you can see one of the roles AWS service role for application migration service. And then we have a number of other roles that all begin with the name AWS application migration. So if I deselect this and type AWS, application, you can see all of those various AWS application migration roles. And the reason why I wanted to show you these roles is because we are going to be using these roles a little bit later on in this course. At any rate, that's how you go about initializing the application migration service, and these are the roles that are created as a result of that initialization process.
