What is Amazon Web Services (AWS)?

Hey there, I'm Michael from CodeCloud.

Welcome to this lesson from our AWS cloud practitioner certification course.

In this video, we'll help you build a strong foundation in cloud computing with AWS. So, if you want to learn more

with AWS. So, if you want to learn more or go deeper, check out the full course details below and let's get started. All right, welcome back. Let's

started. All right, welcome back. Let's

talk about specifically what Amazon Web Services is. So, just like we did with

Services is. So, just like we did with cloud computing, we're going to talk just a moment about how AWS compares to traditional IT and where the difference

exists in case you didn't quite gro it or understand it when we did it with cloud computing. Okay? So, I want you to

cloud computing. Okay? So, I want you to think of it this way. Think of a traditional IT shop as you having to get a kitchen, cheese, tomatoes, everything

you need to make a pizza. you're making

it yourself. You're making you have to put all the components together. Or if

you don't mind losing a little bit of control, you could just go to Pizza Hut.

Now, I chose Pizza Hut because I think Pizza Hut is pretty decent. Obviously,

there are specialty pizza shops that are better, but I digress. What's important

here is that Amazon Web Services is like a place that you go to have a lot of those operational concerns offloaded. So

think of it as having a pizza made for you where you just consume pizza versus in traditional IT where you are having to make the pizza

yourself. Now if we convert that to our

yourself. Now if we convert that to our tech idea that we had before in cloud computing imagine that you want to produce an idea with new tech but this

time you're not using traditional IT you're using AWS. Now, here's what happens in our original request. For

traditional data center requests, you had to request the hard the server hardware like racks and stuff like that.

You had to request the networking cables, the internet connection. You had

to request power. You had to request server placement with cooling. You had

to have operations and security come in and install. And then you got access.

and install. And then you got access.

And then once you had access and sometimes this could take days, this could take weeks, this could take months, then you were free to install your software that you were looking for.

AWS this is not how things happen. With

AWS, this is much different. So instead,

it's a lot more automated. So instead of having to provision hardware, you just talk to a hardware service that includes all the networking, the cooling, and the power already.

Now instead of managing physical objects like data centers where they're cooling and power and servers, you're now just accessing services like virtual machine

services or database services or application services and all you're doing at that point is in most cases they're already installed and you just configure with ease what it is that

you're looking for. So if we look back at our original diagram about what is cloud computing, you know, you notice that the basic components are here.

You've got networking at the top and you've got computers in the upper right hand side and you've got disk and data storage and you've got governance and security and all the stuff like just

right here. Right? So imagine if all of

right here. Right? So imagine if all of these was replaced with specific services or groups of services inside of

AWS or Amazon Web Services. And this is the secret sauce

Services. And this is the secret sauce is that AWS wants to consume and eat your operational overhead. They want to eat some of your security overhead. They

want it. They want you to spend your money with them so that they can take that off your plate, right? And we'll

get into why that is later, but this is what Amazon Web Services does. Now, there's these core service

does. Now, there's these core service categories. So, we've got compute, we've

categories. So, we've got compute, we've got storage, which is could also be data, right? Then we've got our

data, right? Then we've got our networking and content delivery, and this is where we get internet access, and this is how we control things like firewalls and security and stuff like that. We've got databases in the lower

that. We've got databases in the lower left hand side and this is you know databases like that are kind of more cutting edge like MongoDB or it could be your traditional databases like Oracle

and Microsoft etc etc and then you've got the things you need to get these other four categories to work which is security identity and compliance and of course you do need some management and

governance even at a startup because you know who's going to manage these systems right who's going to monitor them when they're down who's going to make sure they're patched that kind of

So these are the core service categories. Now there's three ways that

categories. Now there's three ways that you can interact with AWS. Now these are the three kind of

AWS. Now these are the three kind of general ways. Obviously you can get to

general ways. Obviously you can get to the details and there's more but the first is that Amazon has a product called their management console which is just nothing more than a web page. We're

going to look at that in just a second.

And the web page is great to learn and confirm. They call this the console.

confirm. They call this the console.

They call it the management console.

Sometimes they call it the Amazon the AWS web page. But this is one of the first easiest learned ways to interact and create objects on

AWS. The second is called the AWS

AWS. The second is called the AWS command line interface. And this is where you type in commands such as AWS

space EC2 space describe instances. And

what you're doing is you are using AWS's preconfigured command line, pre-built command line, and you have to do some authentication setup. And it's very easy

authentication setup. And it's very easy to do that. And what it does is it allows you to type in commands into your terminal, and it will actually talk to AWS. And you can both get information

AWS. And you can both get information and you can manipulate objects and services out on AWS as well.

This is great for engineers, developers of all types, but particularly operations folks tend to find the CLI, the AWS command line interface to be spectacular. Third, and certainly not

spectacular. Third, and certainly not the least, but arguably also the most powerful, is that AWS has what's has what's called software development kits.

Think of these as libraries of actions that you can stick inside of your application. So, let's say you're a

application. So, let's say you're a Python developer, just as an example, and you're like, I really want to manipulate virtual machines in AWS.

Well, AWS has a software development kit for Python where you can import the libraries necessary to manipulate virtual machines or to manipulate

containers or to create networking. And

they have it for most major languages.

So, they have it for Java, they have it for JavaScript. You can see Ruby up

for JavaScript. You can see Ruby up here. And this is really for people who

here. And this is really for people who like write code in all of the different variations of that role. So there's

three ways. There's the console, there's the CLI, and then there's software development kits are the three ways that people generally interact with

AWS. So let's switch gears for just a

AWS. So let's switch gears for just a second and let's roll over to the management console. So this is the

management console. So this is the management console and as you can see here it's got that compute category that we saw earlier. It's got that storage

category that we saw earlier. Here's the

database category. Up here is the management and governance category. Here

is security and compliance. We also got other things like cost management, machine learning. Here's the networking

machine learning. Here's the networking and content delivery. And notice there's a bunch of other things out here. You do

not need to know everything that AWS has to offer. If you are intimidated by even

to offer. If you are intimidated by even seeing this web page, congratulations.

You're a human being. We all get overwhelmed. I've been doing this for 12

overwhelmed. I've been doing this for 12 years. Even I look at this and go, "Oh,

years. Even I look at this and go, "Oh, that's a lot." Right? So, take that in because you do not need to know everything here, but you probably need to know just one or two sentences about

EC2. maybe a few sentences about S3. So,

EC2. maybe a few sentences about S3. So,

there's a number of services, which is exactly why you're taking this course, that are going to guide you through what you need to know to pass the cloud practitioner exam. Be aware that this is

practitioner exam. Be aware that this is the web interface. So, by the way, we could come in here and click on S3, and this would take us into the S3 interface. Notice there's going to be a

interface. Notice there's going to be a bunch of words here that nobody really understands. And then we're going to see

understands. And then we're going to see all of our buckets that we use for various tasks inside of AWS.

That is the web console. So you're going to see a lot more of that, but I just wanted to give you a brief taste and now we're going to get back to our presentation. So we took a little tour

presentation. So we took a little tour of the console and now we're at the end.

So we can summarize a little bit. So

what is AWS? So if cloud computing is the ondemand consumption of it resources, just know that AWS was the first large-scale cloud provider. They

were the ones who pioneered the ondemand delivery of IT resources. So the first arguably the largest, they definitely have the largest market share. So it's a great place to start when you're looking

for a certification. Second, AWS was launched

certification. Second, AWS was launched in 2006 with S3 as the first service and they announced actually SQS shortly thereafter, which you're going to learn what the S3 and SQS are, but basically

S3 is the storage service. Think of it as like kind of like Google Drive or Dropbox. Since then, AWS has grown to

Dropbox. Since then, AWS has grown to 300 plus macro services. So, really

large services that have subservices underneath them. But don't panic. You're

underneath them. But don't panic. You're

only going to learn about maybe 20 to 30 of those services at the most superficial level. You are not going to

superficial level. You are not going to have to know how to deploy, master, design, architects. And so, when we get

design, architects. And so, when we get to the exam guide, you're going to see that you just at this level, you really just need to be able to talk about AWS.

But there are 300 plus services out there.

And just know that signing up for AWS, if you want to get off this video and go right away with a phone number and a credit card and sign up for an account, signing up is free. And most of the

services actually are free or have a free tier, which we were going to talk about through this course. But at some point, a lot of the services are pay to use, meaning if you start up a virtual machine, you're going to pay for the

virtual machine as an example. And last

but not least, just know that AWS has one of the largest communities, the largest market position, and even to this day, still some of the largest growth in the industry as it relates to

hypers scale cloud providers. If you're ready to take your
