5.1 EC2 Overview

00:00

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
