In this lesson we're going to show you how to get setup with Amazon Web Services,
AWS for short.
going to show you how to sign up for an account, set up users, policies and keys.
So the key things are going to be permissions,
how to download key pairs, and show you a little bit of the SDK.
So it's going to be mostly hands-on.
We're going to walk you, screen cast the entire process.
Sergio Luna here is going to walk you through this.
So it'll help If you sign up for an account and
then follow along with this lesson.
Having said that, I'll let Sergio take it from here,
we're going to switch to the web now.
>> Okay, so the first thing you're going to
want to do is create your account.
It's important to know that you're going to need a credit card and
the free tier is only 12 months long.
So after 12 months,
they're going to start charging you if you're currently using their services.
When you click Create Account, you're going to come to this page right here.
Where you're going to enter your account name, your email, and a password.
Once you hit Continue, it'll go to this next page where, initially,
it's going to be on Company Account.
You're probably going to want a personal account, because this just for
your own personal use.
You fill out all this information, and then you fill
out the credit card info on the next page and you are going to be ready to go.
It's important to note also that you are probably going to want to set up a billing
alarm just in case you go over the free tier's alloted services.
Say you have an EC2 instance and It's being used too much,
or you have a size that's too big, so you're going to want to know that.
And you can set up billing alarms so that Amazon emails you or
notifies you however you want to so you can cancel it right away.
>> We know there's a free tier account in the US.
But if some of you are watching from China, India, Brazil or
any other country I'm sure there is some free tier for you guys.
See if not, just post on the board, see what you can do.
But you can also use other cloud services, like Microsoft or
Google as I mentioned earlier.
But we chose Amazon because it was the most popular service out there.
>> And now, you're going to be on the home page after you log in.
And the first thing you're going to want to look at are user roles and
policies that you can create.
You can click up here on Services.
And down here which is a security identity and compliance, you can click on IAM.
And here is where you can create users, so
that you can collaborate with other people.
When you're logged in, as now, you're the root account, you own this account.
And you can create users who can view and
use your services as much as you allow them to.
You create policies that denote how much they're allowed to use it.
To create one, you just go right here on this tab where it says Users, and
up top you would add a user.
Create the user name, and it's going to flow through Permissions, you're
going to review, and it's going to say do you want to create the password for them?
Do you want them to write their own password?
Give us their email.
Information like that and then you're going to end up with a user, like this.
You would have already created some permissions for them but
you can also go back in and edit them whenever you want.
So you would just come in to where it says Users, click on your user,
the user your created.
And then in the permissions tab you can go to Add Permissions.
You're going to want to look at existing policies directly because
those are policies that Amazon writes for you.
You don't have to worry about coding it exactly as they want it.
So let's say you wanted to give this user EC2 instant services.
You will type in EC2/ right here in the search bar, look for
Amazon EC2 Full Access.
Click on it and you just continue through here, you add permissions.
And there you go, now this user's allowed to create, edit, and
do anything that EC2 is allowed to do.
And it's important to note that when you give a user access like this,
it's going to allow them to use your credit card.
So they can create instances and
maybe they're going to create one that's not allotted in the free tier.
It's going to be all on your information,
your credit card is used even though it's their user account.
From there,
once you have a user if you want to be able to use AWS Client in a terminal.
What you would want to do is, first setup what are called access keys.
There's an access key, a public one and a private one.
It's very important to note that you can only download this once.
Once you've downloaded it, you can't download it again.
So I recommend backing it up more than once, backing it up onto a device and
then onto a different device, just in case you lose it.
The way you would do that is once again, you go to the,
actually you can come up here, where your username is.
Go to my security credentials.
You can skip this.
And where it says access keys, right here, you're going to want to click on that and
say create new access key.
It's going to tell you download this file now and
you're not going to be able to download it again.
So go ahead and download it and there's the access key.
If you want to take a look at what it looks like, it's just a comma separated.
It's going to show you your access key right here, this one's public.
You can find this on Amazon on your account.
But down here, the secret key, only you have this.
That's why you want to back this up and
download it to a couple of secure devices so that you don't ever lose it.
And if it were the case that you do lose it, you can always come in here and
make an active on one of your older keys that you're no longer using.
Or that you forgot the information for.
And once it's inactive, you can no longer use it.
The reason you have to make one inactive is because you're only allowed to have two
at a time, that's the max you can ever have.
And if you need another one, the only option you have is to delete
one of your older ones and create one of the newer ones.
So now using your AWS access key
you can download the AWS client onto your terminal.
To do that on Ubuntu it's pseudo app get install aws play.
Hit downloads, go ahead and say yes.
And while that's downloading you can go ahead and copy and
paste your values because we're going to need those right now.
Okay, so now you have AWS and you're going to want to run AWS Configure.
So it's going to ask you right here, what is your access key?
Go ahead and paste that one in.
And then it's going to ask you, well what's your secret key?
So we're going to copy that.
And paste that one in, then it's going to ask you what region you want to use.
We're going to go ahead and use US West 1.
And then it's going to ask you the output format.
I recommend you use JSON, because it's the easiest to work with.
>> So for regions, people in other countries,
where do they find their available regions?
>> You can Google AWS regions And
it'll show you a list of everything that they have right here.
These regions are the denoted in your account when you look up to the top right.
Let's say I want to go into a service, it's not important.
Up here is the region that you're currently working in.
So we're in US West, which happens to be US West 1, right here.
And once you've done that for your AWS client you can use
any of the services that they have, like- >> You
may want to increase your screen size.
>> Yeah.
>> Control plus, there you go.
You run AWS S3, so you want to list what you have.
And it's going to show you, these are the buckets you have for, say, S3.
And you can just check the type of commands you can run with AWS help.
And it'll show you a whole list of things you can do on here,
and that's for the AWS client.
So if you want to work with your AWS account through the terminal, and
you don't want to have to download some third party library, you can use that.
And the only thing aside from that,
is if you wanted to write code for your AWS services.
Like let's say you want to write something in PHP, You look for the AWS SDK for PHP.
You go ahead and go in here, and you would just follow the instructions on here to be
able to write actual code that will pull information from any of your AWS services.
In this, you're also going to need to supply your access keys and
your secret key.
It's just going to be written in code and
you're going to want to make sure that's secure.
So that's how you set up AWS Client and your users and
the overlook at the SDKs that they have.
