in this module, we will discuss what is the cloud
I will provide you with a brief history of AWS
and we will identify the different types of cloud service is
what is cloud computing?
In a nutshell. Cloud computing is simply the on demand delivery of compute power.
This could be in the form of databases,
software, analytics applications
and other I. T Resource is
is delivered over the Internet
with the pay as you go pricing model.
It doesn't matter whether you are running a gaming app
or supporting your company's critical infrastructure, because on a cloud service platform
you will have nearly instant access to I. T. Resource is without having to spend a ton of money up front.
This is truly a game changer, since historically,
business would have to make a huge capital investment up front in the form of hardware, facilities,
the cost of managing all of these I t resource is
with cloud computing. One can provision exactly the resource is needed
and pay for only what's used.
So how did AWS come into existence?
As I began to research this question,
I was surprised to learn that there were many stories about how AWS started.
The one that appears to be the most consistent
comes from Andy Jassy, the current CEO of Amazon Web service is
Mr Jackson explains that AWS was born over roughly a three year period from 2000 to 2003.
In 2000 Amazon was attempting to launch a new e commerce service over its existing Amazon e commerce platform.
The company found this task to be extremely difficult to accomplish over their existing monstrous infrastructure.
Amazon have been growing so rapidly between 1994 and 2000
that the company had not really planned for such exponential growth.
Amazon didn't truly have independent development platform.
There was just a huge environment of interdependent systems.
To solve this problem,
Amazon software engineers began to float. The idea of decoupled service's
or service is that didn't depend on other service is
they began to create well documented application programming interfaces, or AP eyes,
which are essentially software tools such as communication protocols and subroutine definitions for building software programs.
At first, these AP eyes were shared on Lee internally among Amazon developers,
teams reuse other Amazon teams AP eyes
as building blocks for their own individual projects.
At some point, the executives at Amazon began to understand that if their own internal teams were becoming far more efficient by sharing a P eyes,
then why not expand this concept into a business model?
The idea developed over a three year period,
and in 2003 the execs at Amazon began to envision an operating system for the Internet,
where a company could build products and service is from scratch,
even from a college dorm or kitchen table if the right tools were readily available,
almost like a box of Legos.
Amazon Web service is was launched.
It's first service offering was the Amazon and elastic compute clout, or Amazon, Easy to,
which was essentially an online virtual machine designed to make it easier for developers to scale their Web applications.
The idea was so new and swift that Amazon did not have a true competitors in the space until 2010 when Microsoft launched
which later became Microsoft Azure.
This helps to explain why A W S remains the dominant player in cloud technology
types of cloud computing.
Several types of cloud models have evolved
to assist developers and I T departments to select the right solution for their needs.
Different models offer varying levels of management,
flexibility and control.
It is important to understand the differences between the different models
to select the best strategy for your use cases.
Infrastructure as a service
is a standardized, highly automated offering were compute. Resource is
complemented by storage and networking capabilities,
Our owned and hosted by a service provider and offered to customers on demand.
Customers are able to self provision this infrastructure using a Web based graphical user interface that serves as an I T operations management consul for the overall environment.
AP I Access to the infrastructure may also be offered as an option.
Platform as a service
is a broad collection of application infrastructure. Middleware Service's,
including application platform
business process management and database service, is
software as a service.
Software as a service is a model for the distribution of software, where customers access software over the Internet.
a service provider host the application at its data center, and a customer accesses it
via standard Web browser.
There are a few major characteristics that apply to most
Updates are applied automatically without customer intervention.
The service is purchased on a subscription basis.
No hardware is required to be installed by the customer
Cloud Computing deployment models.
There are essentially three different cloud deployment models,
within a cloud deployment model.
The entire application and supporting infrastructure is running the clout
Within the hybrid cloud deployment model,
applications are shared and run between cloud based and on premises. Resource is
Within this deployment model
cloud computing resource is are utilized primarily by a single business or organization.
The resource is may be located on the premises of the organization's data center, or perhaps in 1/3 party co location. Facility.
A W S contains several cloud offerings that can be assembled in a myriad of ways to produce service's or functions
customized for the needs of your business or client offerings.
One can access these cloud service is via the AWS management console,
the command line interface
or via a software development kit.
This contains Amazon Easy to
Amazon, easy to container service
and AWS elastic beanstalk just to name a few
Among these service is our Amazon s three
Amazon elastic block store
Amazon offers database service is such a CZ Amazon Aurora
Amazon Dynamo database, and
I was on the last two cash
networking and content delivery.
Among the most important service is offered by A W S
is the Amazon Virtual Private Cloud, or V P. C.
This is where you can build your own private segment of AWS Cloud
and launch your own AWS. Elements in a private virtual network that you create and manage
also, under the networking content delivery umbrella are complementary. Service is such a CZ. Amazon Cloudfront
Amazon Direct connect
and elastic load balancing,
Security, identity and compliance. These air the service is that allow you to create policies to secure access to your AWS. Resource is manage users and groups
provide key management service is and even Web application. Firewall Service's
among the other. Service is offered by a W S R
developer and management tools,
Internet of things or I ot
desktop in AP streaming
and even game development Service's
The AWS service offering is simply incredible and continues to grow
in future lessons. We will take a deeper dive into some of this course service's and build out our own VPC
