We will use Amazon Web Services,
AWS, as the example to learn how to do data management in the cloud.
AWS is one of the earliest cloud computing services,
and today it is also still the largest cloud computing service.
It has the highest, the largest share of the market.

AWS is a fleet of major many types of services and
we're going to focus on the most fundamental services from
AWS that include Computing and Storage and Messaging.
Compute is the type of services that the users will need to run
the applications and Storage is what we
need for the applications to store data and access data.
And Messaging is what we need for the application to communicate with one another and
even for the individual components from
the same application to interact with one another.
So these are the three most fundamental ones.
And this is a picture that I took from AWS
which lists all the major services that are available from AWS.
It is really many of them.
On top of the physical,
AWS Global Physical Infrastructure.
And we have the most fundamental one here Compute,
Storage and the Messaging link right here and we also have Database.
And then on top of this fundamental service system we can have
many other services provided by AWS including monitoring service,
auto scale service, and content delivery service and many others.
So, we'll study the most fundamental ones
in this class and then where you try to use them to do data process and data management.
When we use AWS,
when you work on your projects and homeworks,
try to use the resources that are offered from the Free Usage Tier.
So, almost all the major cloud provider have a free tier to give
you some amount of resources with some limited capabilities.
Resources in the free tier they are most likely enough for
our projects and try to
use them as much as you can so that you do not incur unnecessary charge.

So this is a typical example is one of the success example from AWS to tell us why and
also it helps us to know why cloud computing is so important and
why it is so successful and in the case of AWS why it is so successful.
And this actually is a real example happened back in 2008.
Is about a story from a video service company which is called animoto dot com.
This is a company which provides a service where
you can upload your images and videos and they
help you compare them to guide and to make a company story out of it.
So, and this particular service was hosting AWS.
At the beginning this service was using only about 40 instances in total from AWS.
And at one particular day,
this is April 18th,
the company successfully launched this animoto dot com,
a viral campaign on Facebook.
And that company's advertisement was so successful
and it caused a huge surge in demand of their service.
And because the service was provided by AWS
and they were able to handle that huge surge, as a result,
under just three days the level of instances that this company was
using from AWS grew from 40 all the way to 5,000 here.
And this growth is only possible when you run your service,
run your application in the cloud computing system because of the rapid of
elasticity and because they are demand service that is provided by cloud computing.
And so, this is a very good example of the advantages
of cloud computing and also why AWS is so successful.
