Cloud computing
Summary
TLDRCloud computing, as defined by the U.S National Institute of Standards and Technology, is an IT usage model characterized by on-demand self-service, broad network access, resource pooling, elasticity, and pay-as-you-go pricing. This technology allows customers to access computing resources like processing power and storage over the internet, without the need for human intervention. The video script introduces the concept of IT infrastructure, comparing it to a city's infrastructure, and outlines the exploration of Google Cloud's infrastructure services, aiming to familiarize viewers with their functionalities and potential applications.
Takeaways

- đ§ **Resource Pooling**: Providers maintain a large pool of resources to serve multiple users, which enables cost-effective bulk purchasing and savings passed on to customers.
- đ **Location Independence**: Users are not concerned with the physical location of the provided resources, enhancing flexibility.
- đ **Elasticity**: Resources can be rapidly and elastically increased or decreased based on demand, allowing for scalability and cost efficiency.
- đž **Pay-as-you-go**: Customers are billed based on actual usage or reserved capacity, aligning costs with utilization.
- đïž **IT Infrastructure Analogy**: IT infrastructure can be likened to a city's infrastructure, with users, applications, and services supported by underlying systems.
- đ **Google Cloud Services**: The course will cover IT infrastructure services provided by Google Cloud, helping learners understand their functionalities.
- đ **Learning Outcomes**: Participants will gain familiarity with Google Cloud's infrastructure services and begin to grasp their practical applications.
Q & A
What is the origin of the term 'cloud computing'?
-The term 'cloud computing' was created by the U.S National Institute of Standards and Technology.
What are the five key traits of cloud computing?
-The five key traits of cloud computing are on-demand self-service, broad network access, resource pooling, elasticity, and measured service.
How does on-demand self-service in cloud computing benefit users?
-On-demand self-service allows users to obtain processing power, storage, and network resources without human intervention through a web interface.
What does it mean for cloud computing resources to have 'broad network access'?
-Broad network access means that users can access computing resources over the internet from anywhere they have a connection.
How does resource pooling in cloud computing benefit the provider and the customers?
-Resource pooling allows the provider to have a large pool of resources, which they can allocate to users as needed. This enables the provider to buy in bulk and pass the savings onto the customers.
Why do customers not need to know the physical location of cloud computing resources?
-Customers don't need to know the exact physical location of resources because the cloud provider manages the infrastructure and ensures accessibility.
What is meant by the 'elasticity' of cloud computing resources?
-Elasticity refers to the ability of cloud computing resources to automatically increase or decrease as needed, allowing customers to scale up or down quickly.
How does the payment model in cloud computing differ from traditional IT services?
-In cloud computing, customers pay only for what they use or reserve as they go, unlike traditional IT services where they might pay for fixed resources regardless of usage.
What is the role of IT infrastructure in cloud computing?
-IT infrastructure in cloud computing is the underlying framework of facilities and systems that support the delivery of services, similar to how a city's infrastructure supports its functions.
How does the analogy of a city's infrastructure help in understanding IT infrastructure?
-In the analogy, people in the city represent users in IT, cars and bikes represent applications, and the services provided are like the applications running on the infrastructure.
What will be the focus of the course on IT infrastructure services provided by Google Cloud?
-The course will focus on exploring the IT infrastructure services offered by Google Cloud, helping participants understand what the services do and how to use them.
Outlines
đ Introduction to Cloud Computing
The paragraph introduces cloud computing as a popular and versatile technology. It explains the term's origin from the U.S National Institute of Standards and Technology and outlines its five key characteristics: on-demand self-service, broad network access, resource pooling, elasticity, and pay-per-use. The analogy of IT infrastructure to a city's infrastructure is used to illustrate the concept, where IT infrastructure encompasses the foundational systems and services that support applications and users, similar to how a city's infrastructure supports its residents and services.

Highlights
Cloud computing is a hot topic and a way of using information technology resources.
The U.S National Institute of Standards and technology coined the term 'cloud computing'.
Cloud computing has five key traits that are equally important.
Customers receive computing resources on-demand and self-service through a web interface.
Resources are accessed over the internet from any location with a connection.
Providers maintain a large pool of resources and allocate them to users.
Providers can buy resources in bulk and pass the savings onto customers.
Customers do not need to know the physical location of the resources.
Resources are elastic, allowing for scaling up or down as needed.
Customers pay only for what they use or reserve, with no usage, no payment.
An infrastructure is the underlying framework of facilities and systems.
IT infrastructure can be compared to a city's infrastructure, including essential services.
In IT infrastructure, users are like city inhabitants, and applications are like vehicles and buildings.
The course explores IT infrastructure services provided by Google Cloud.
Students will become familiar with Google Cloud's infrastructure services.
The course aims to help students understand how to use Google Cloud's services.
Transcripts
let's get started with cloud computing
the cloud is a Hot Topic these days but
what exactly is it
the U.S National Institute of Standards
and technology created the term cloud
computing although there's nothing U.S
specific about it
cloud computing is a way of using
information technology or it that has
these five equally important traits
first customers get Computing resources
that are on demand in self-service
through a web interface users get the
processing power storage and network
they need with no need for human
intervention
second customers get access to those
resources over the internet from
anywhere they have a connection
third the provider of those resources
has a large pool of them and allocates
them to users out of that pool
that allows the provider to buy in bulk
and pass the savings onto the customers
customers don't have to know or care
about the exact physical location of
those resources
fourth the resources are elastic which
means that they can increase or decrease
as needed so customers can be flexible
if they need more resources they can get
more and quickly if they need less they
can scale back
and finally the customers pay only for
what they use or Reserve as they go
if they stop using resources they stop
paying
that's it that's the definition of cloud
computing
an infrastructure is the basic
underlying framework of facilities and
systems so it might be helpful to think
about it or information technology
infrastructure in terms of a city's
infrastructure
in a city the infrastructure includes
Transportation Communications power
water fuel and other essential services
comparing it to it infrastructure the
people in the city are like users in the
cars bikes and buildings are like
applications
everything that goes into creating and
supporting those Services is the
infrastructure
in this course you'll explore the it
infrastructure Services provided by
Google Cloud
you'll become familiar enough with the
infrastructure services to know what the
services do and you'll start to
understand how to use them
