in this module, we will discuss what is the cloud
00:05
I will provide you with a brief history of AWS
00:08
and we will identify the different types of cloud service is
00:26
what is cloud computing?
00:29
In a nutshell. Cloud computing is simply the on demand delivery of compute power.
00:35
This could be in the form of databases,
00:38
storage,
00:39
networking
00:41
software, analytics applications
00:44
and other I. T Resource is
00:46
is delivered over the Internet
00:48
or the cloud
00:50
with the pay as you go pricing model.
00:52
It doesn't matter whether you are running a gaming app
00:55
or supporting your company's critical infrastructure, because on a cloud service platform
01:00
you will have nearly instant access to I. T. Resource is without having to spend a ton of money up front.
01:07
This is truly a game changer, since historically,
01:10
business would have to make a huge capital investment up front in the form of hardware, facilities,
01:17
power
01:18
and, of course,
01:19
the cost of managing all of these I t resource is
01:23
with cloud computing. One can provision exactly the resource is needed
01:27
and pay for only what's used.
01:45
So how did AWS come into existence?
01:48
As I began to research this question,
01:51
I was surprised to learn that there were many stories about how AWS started.
01:56
The one that appears to be the most consistent
01:57
comes from Andy Jassy, the current CEO of Amazon Web service is
02:04
Mr Jackson explains that AWS was born over roughly a three year period from 2000 to 2003.
02:13
In 2000 Amazon was attempting to launch a new e commerce service over its existing Amazon e commerce platform.
02:21
The company found this task to be extremely difficult to accomplish over their existing monstrous infrastructure.
02:28
Amazon have been growing so rapidly between 1994 and 2000
02:32
that the company had not really planned for such exponential growth.
02:37
Amazon didn't truly have independent development platform.
02:42
There was just a huge environment of interdependent systems.
02:47
To solve this problem,
02:51
Amazon software engineers began to float. The idea of decoupled service's
02:55
or service is that didn't depend on other service is
03:00
they began to create well documented application programming interfaces, or AP eyes,
03:06
which are essentially software tools such as communication protocols and subroutine definitions for building software programs.
03:16
At first, these AP eyes were shared on Lee internally among Amazon developers,
03:22
teams reuse other Amazon teams AP eyes
03:24
as building blocks for their own individual projects.
03:29
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,
03:38
then why not expand this concept into a business model?
03:42
The idea developed over a three year period,
03:45
and in 2003 the execs at Amazon began to envision an operating system for the Internet,
03:52
where a company could build products and service is from scratch,
03:55
even from a college dorm or kitchen table if the right tools were readily available,
04:01
almost like a box of Legos.
04:04
In August 2006
04:08
Amazon Web service is was launched.
04:11
It's first service offering was the Amazon and elastic compute clout, or Amazon, Easy to,
04:18
which was essentially an online virtual machine designed to make it easier for developers to scale their Web applications.
04:28
The idea was so new and swift that Amazon did not have a true competitors in the space until 2010 when Microsoft launched
04:36
Project Red Dog,
04:39
which later became Microsoft Azure.
04:42
This helps to explain why A W S remains the dominant player in cloud technology
05:08
types of cloud computing.
05:11
Several types of cloud models have evolved
05:14
to assist developers and I T departments to select the right solution for their needs.
05:20
Different models offer varying levels of management,
05:24
flexibility and control.
05:27
It is important to understand the differences between the different models
05:30
to select the best strategy for your use cases.
05:34
Infrastructure as a service
05:38
is a standardized, highly automated offering were compute. Resource is
05:43
complemented by storage and networking capabilities,
05:46
Our owned and hosted by a service provider and offered to customers on demand.
05:53
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.
06:04
AP I Access to the infrastructure may also be offered as an option.
06:14
Platform as a service
06:15
is a broad collection of application infrastructure. Middleware Service's,
06:20
including application platform
06:23
integration,
06:25
business process management and database service, is
06:30
software as a service.
06:32
Software as a service is a model for the distribution of software, where customers access software over the Internet.
06:41
In SAS,
06:43
a service provider host the application at its data center, and a customer accesses it
06:48
via standard Web browser.
06:51
There are a few major characteristics that apply to most
06:56
SAS vendors.
06:59
Updates are applied automatically without customer intervention.
07:02
The service is purchased on a subscription basis.
07:08
No hardware is required to be installed by the customer
07:12
Cloud Computing deployment models.
07:15
There are essentially three different cloud deployment models,
07:18
cloud
07:19
hybrid
07:20
and on premises,
07:23
cloud
07:24
within a cloud deployment model.
07:27
The entire application and supporting infrastructure is running the clout
07:31
hybrid
07:32
Within the hybrid cloud deployment model,
07:35
applications are shared and run between cloud based and on premises. Resource is
07:42
private cloud.
07:44
Within this deployment model
07:46
cloud computing resource is are utilized primarily by a single business or organization.
07:51
The resource is may be located on the premises of the organization's data center, or perhaps in 1/3 party co location. Facility.
08:01
A W S contains several cloud offerings that can be assembled in a myriad of ways to produce service's or functions
08:09
customized for the needs of your business or client offerings.
08:13
One can access these cloud service is via the AWS management console,
08:18
the command line interface
08:20
or via a software development kit.
08:26
Compute Service's.
08:28
This contains Amazon Easy to
08:31
Amazon, easy to container service
08:35
and AWS elastic beanstalk just to name a few
08:39
storage.
08:41
Among these service is our Amazon s three
08:45
Amazon elastic block store
08:46
and Amazon Glacier
08:50
database.
08:50
Amazon offers database service is such a CZ Amazon Aurora
08:56
Amazon R D s
08:58
Amazon Dynamo database, and
09:01
I was on the last two cash
09:03
networking and content delivery.
09:07
Among the most important service is offered by A W S
09:11
is the Amazon Virtual Private Cloud, or V P. C.
09:13
This is where you can build your own private segment of AWS Cloud
09:18
and launch your own AWS. Elements in a private virtual network that you create and manage
09:24
also, under the networking content delivery umbrella are complementary. Service is such a CZ. Amazon Cloudfront
09:31
Amazon Route 53
09:35
Amazon Direct connect
09:37
and elastic load balancing,
09:41
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
09:50
provide key management service is and even Web application. Firewall Service's
09:56
among the other. Service is offered by a W S R
10:01
migration tools,
10:03
developer and management tools,
10:05
analytics,
10:07
artificial intelligence,
10:09
mobile applications,
10:11
messaging,
10:13
Internet of things or I ot
10:16
desktop in AP streaming
10:18
and even game development Service's
10:22
The AWS service offering is simply incredible and continues to grow
10:28
in future lessons. We will take a deeper dive into some of this course service's and build out our own VPC
10:37
in this module we discussed. What is the cloud
10:41
I provided you with a brief history of AWS
10:45
and we identify the different types of cloud service?
