What is cloud computing?

Cloud computing is a way of using IT that provides on-demand resources over the internet.

How does resource pooling work in cloud computing?

Providers allocate resources from a large pool, allowing them to buy in bulk and pass savings to customers.

What does elasticity mean in cloud computing?

Elasticity refers to the ability to increase or decrease resources as needed.

How do customers pay for cloud services?

Customers pay only for what they use or reserve, stopping payments when they stop using resources.

What is IT infrastructure?

IT infrastructure is the basic framework of facilities and systems that support IT services.

How is IT infrastructure compared to a city's infrastructure?

In this analogy, users are like people in a city, while applications are like cars and buildings.

What will be covered in the course?

The course will explore IT infrastructure services provided by Google Cloud and how to use them.

Let's get started with cloud computing.
00:00:03
The cloud is a hot topic these days,
00:00:04
but what exactly is it?
00:00:07
The US National Institute of Standards and Technology
00:00:10
created the term cloud computing,
00:00:12
although there's nothing US-specific about it.
00:00:15
Cloud computing is a way of using information technology, or IT,
00:00:19
that has these five equally important traits.
00:00:22
First, customers get computing resources that are on demand and self-service.
00:00:27
Through a web interface, users get the processing power, storage,
00:00:32
and network they need with no need for human intervention.
00:00:36
Second, customers get access to those resources over the internet,
00:00:40
from anywhere they have a connection.
00:00:43
Third, the provider of those resources has a large pool of them
00:00:47
and allocates them to users out of that pool.
00:00:50
That allows the provider to buy in bulk and pass the savings onto the customers.
00:00:55
Customers don't have to know or care
00:00:57
about the exact physical location of those resources.
00:01:01
Fourth, the resources are elastic,
00:01:04
which means that they can increase or decrease as needed,
00:01:07
so customers can be flexible.
00:01:09
If they need more resources, they can get more, and quickly.
00:01:13
If they need less, they can scale back.
00:01:16
And finally, the customers pay only
00:01:19
for what they use or reserve as they go.
00:01:22
If they stop using resources, they stop paying.
00:01:26
That's it.
00:01:27
That's the definition of cloud computing.
00:01:30
An infrastructure is the basic underlying framework of facilities and systems.
00:01:34
So it might be helpful to think about IT, or information technology,
00:01:38
infrastructure in terms of a city's infrastructure.
00:01:41
In a city, the infrastructure includes transportation, communications,
00:01:46
power, water, fuel and other essential services.
00:01:50
Comparing it to IT infrastructure,
00:01:52
the people in the city are like ‘users,’
00:01:54
and the cars, bikes, and buildings are like ‘applications.’
00:01:58
Everything that goes into creating and supporting those services is
00:02:01
the infrastructure.
00:02:03
In this course, you'll
00:02:04
explore the IT infrastructure services provided by Google Cloud.
00:02:08
You'll become familiar enough with the infrastructure services to know
00:02:11
what the services do, and you'll start to understand how to use them.
