In this video,
00:02
we will provide an overview of Amazon. Easy to.
00:07
We will introduce Amazon machine images.
00:11
We will explore the different instance types,
00:16
and we will explore the concept of elastic block storage.
00:22
In our last video,
00:23
we created a static history website.
00:26
In this video, we will provide an overview of Amazon Easy to.
00:32
So what is Amazon easy to, and what does it do for us?
00:38
Elastic Compute Clout Easy to
00:41
provides us with scalable computing capacity
00:45
in the Amazon Web service is clout.
00:49
An e C. Two instance
00:51
helps to eliminate the requirement for us to spend money on hardware of front.
00:58
This enables us to launch as many virtual servers as required for our purposes.
01:06
We would also be able to configure networking
01:08
security
01:11
and manage our storage needs
01:14
E. C. To also enables us to handle changes in requirements by scaling up or down.
01:19
This greatly reduces the need
01:23
for us to become expert forecasters.
01:26
So what are some of the features of e. C two
01:32
E. C. To consist of virtual computing environments called Instances,
01:37
an Amazon machine image? Or am I
01:41
our pre configured templates? For our instances,
01:46
the A. M I will pre package the basic image that we will need for our server,
01:53
including the operating system
01:55
and additional software.
01:57
It will also contain various configurations from memory,
02:02
CPU
02:04
networking
02:06
and storage capacity. For our instances,
02:09
these are known as instance types.
02:15
We can also provide secure log in information, for instance, is using key pairs
02:21
A W S stores, the public key,
02:24
and we store the private key in a secure location.
02:30
We can create storage volumes for temporary data
02:34
that's deleted when we stop or terminate our instance
02:38
these air known as instant store volumes
02:42
for persistent storage vibes. For our data,
02:46
we can use Amazon Elastic Block Store or Amazon. EBS
02:53
A. W S provides multiple physical locations for our instances and Amazon E. B s volumes.
03:01
These are called regions and availability zones.
03:07
We can launch different types of instances from a single AM I.
03:13
An instance type will determine the hardware of the host computer used for our instance.
03:20
Each instance type will offer various compute and memory capabilities.
03:25
We choose an instance type based on the amount of memory and computing power that we will need
03:31
for the application or software that were planning to run
03:38
instance. Types fall into the following broad categories.
03:43
General Purpose.
03:45
Amazon. Easy to
03:47
a one Instances
03:50
these air used for cost savings
03:52
for scaling out
03:53
arm based applications such as Web servers,
03:58
Containerized Micro Service's think like docker
04:02
cashing fleets
04:03
and distributed data stores.
04:09
Compute optimized.
04:12
These are optimized for compute intensive workloads.
04:16
This includes workloads such as high performance Web servers,
04:21
high performance computing,
04:24
batch processing
04:26
and serving
04:29
highly scalable multi player gaming.
04:31
Video encoding.
04:34
Scientific modeling,
04:38
distributor analytics
04:40
and machine
04:41
deep learning. Inference.
04:46
Memory. Optimize
04:48
These instance. Types are well suited for memory intensive applications, such as high performance databases.
04:56
Distributed Web scale in memory caches,
05:00
midsize in memory databases
05:03
in real time, Big Data Analytics
05:08
and other
05:10
enterprise applications.
05:13
Accelerated computing.
05:15
These are commonly used for machine learning.
05:19
Storage. Optimized
05:23
H One instances would feature up to 16 terabytes of H D D based local storage.
05:31
It will deliver Hai Dous throughput
05:34
and have a balance of compute and memory.
05:40
Amazon easy to pricing.
05:42
So as we know
05:44
Amazon, easy to is free to try for year by the free tier.
05:50
There are four ways to pay for Amazon. Easy two instances, though
05:56
these are on demand.
05:58
Reserved instances
06:00
spot instances,
06:02
and we can also pay for dedicated hosts,
06:06
which provide us, with easy to instance, capacity
06:11
on physical servers dedicated just for our use.
06:17
So on demand,
06:19
with on demand instances, we pay for compute capacity per hour
06:26
or per second,
06:27
depending on which instances that we'd run.
06:30
There aren't any long term commitments or up front payments required.
06:35
We can increase or decrease our compute capacity
06:40
depending on the demands of our application.
06:45
Reserved instances
06:46
provide us with a discount of up to 75%
06:51
compared to the on demand. Instance pricing.
06:56
In addition,
06:57
when reserved instances are assigned to a specific availability zone,
07:01
they provide us with a capacity reservation.
07:06
Amazon. Easy to spot instances Allow us to request spare Amazon easy to computing capacity
07:15
for up to 90% off of the on demand price.
07:18
Now spot instances are really just recommended for
07:23
applications that have flexible start and end times.
07:28
A dedicated host is a physical easy to server
07:32
dedicated for our use
07:35
we might use. This isn't type for compliance
07:39
or application licensing reasons such as VM wear
07:45
or Windows Server.
07:46
These can be purchased
07:47
on demand
07:49
or hourly,
07:51
and it could be purchased as a reservation for up to 70% off of the on demand price.
07:59
So there was lots of new information in this video,
08:03
and I certainly don't expect you to memorize it all.
08:05
In the upcoming lessons. We will launch our own easy two instances and even write a script to load them automatically.
08:13
Then these concepts will begin to make much more sense
08:18
and begin to click
08:20
learning Check.
08:22
What is Amazon easy to,
08:24
and what does it do for us?
08:28
Elastic compute clout
08:31
provides us with scalable computing capacity
08:33
in the Amazon. Web service is cloud
08:37
and easy, to instance, helps to eliminate the requirement for us to spend money on hardware up front.
08:46
What is an Amazon machine image?
08:50
An Amazon machine image or am I tze are pre configured templates. For our instances,
08:58
the A M I will pre package the basic image that we will need for our server, including the operating system and additional software.
09:11
What are the four ways to pay for Amazon? Easy Two instances
09:16
The four ways to pay for
09:20
easy two instances are
09:22
on demand,
09:24
reserved
09:26
spot instances
09:30
and dedicated hosts
09:35
in this video,
09:37
we provided an overview of Amazon. Easy to
09:41
we introduced Amazon machine images or am I CZ.
09:46
We explored the different instance types,
09:52
and we explored the concept
09:54
of elastic block storage.
