In this MOOC, we will learn Cloud Computing basics using AWS as an example, We will guide you to create AWS account, planning AWS resources for your cloud systems, create AWS EC2 instances, access them and configure the popular LAMP web services with MySQL database. We will guide you to create user accounts for your programmer or operators using AWS Identify and Access management GUI, Register your domain name and setup DNS entry for your servers using AWS Route 53 in 22 mintues! and show you how to use AWS Command Line interface to create and managing instances and services programmatically. We then introduce AWS Load balancing feature, create load balancing cluster for scalability and reliability. We also demonstrate how to diagnose the problem introduced by the health check and firewall restriction conflicts. By the end of this course, you should be able to create your own web cluster with mysql databases, setup your users with credentials to manage your AWS resources/virtual machines either through their management control interface or using AWS CLI API using scripts. You will also learn the best practice in cloud security and debugging service interaction issues may arise in the cloud systems.

Secure Server Configuration and Integrated Access Management

In this module, we learn how to sign up AWS account, create/configure/manage AWS EC2 instances, access them and configure the Linux operating system, Apache web server, MySQL database, and PHP server side scripting support. We also learn how to follow the best security practice to create user accounts with different privileges using AWS IAM service. We learn how to use AWS Command Line Interface to create AWS EC2 instances and control AWS Resources. It allows for programming control of the EC2 instances.

In this lesson, we show how to use AWS camera interface on

an AWS instance and allow us to use it to create instance,

start and stop the instance and to associate

elastic IP address with a particular instance.

It allows us to have programmable control on the AWS instance.

For example, it allow us to pick up three instance geography separated by a hour around

the globe and wake them up every eight hours

in a wrong Robbie fashion to save money and be more efficient.

EC2 API is useful when we are dealing with large scale

of system or dealing with complex management requirements.

To make an image from an instance we simply select the instance and then select

the image menu item in

the action menu and choose the choose or create image menu item.

Enter the Image names.

We are going to use for other people or yourself to

recognize and then provide a short descriptions and

then click the create image button on the lower right and it will

take a minute to generate this image and it's pretty fast.

Basically, it's just copy what was a file and the content of

the images and saves that as a template for other people in Chrome.

To launching a image or to clone the image,

we click AMI entry in the images section of the left panel

and we select our coursera CS 691 AMI1 entery here,

and then select the launch menu in the actions menu.

We will go through the same set of configuration process,

the seven step process like before,

but instead of using AMI Amazon the image,

we are now using our own customized one.

Don't forget to choose next, configure instant detail.

Don't do the launching right away because we need to specify the tech name so

that we can uniquely identify the instance

when they are listing in the dashboard in step five.

Okay. So we choose a name this instance cchow_ami2,

so that we can't tell them apart from the previous one.

After setting the security group we open SSF, NTTP and NTTPS,

and also set our home IP address and we can

launch in the instance and it will start within a minute.

So, it's amazing how fast they are.

It used to be a few minutes, quite a few minutes.

Now we can stop and start from our first instance to control

the second instance using the AWS EC2 stop

instance command for and then we will try to restart them.

We just use AWS EC2 stop instance.

To create a new instance,

we can using the AWS EC2 run-instance and this name is kind of misleading.

It's not really that instance is already there.

Here is actually creating the instance,

so to actually start and stop,

we are not using run we are using the start and stop-instance.

Run instance is actually creating it from an image.

We first need to find out what other image ID, specific image ID.

It can be from AWS,

can be from support window,

can be from our own creations.

Then we also need to find out what is the security group ID and this security group

ID will set up and open up the specific pool the firewall to allow outside access.

We can find a security group ID,

lets say we like using the same image app while we set up instance we set up

we can click on the instance and then click on the security group information,

which will just show up in the lower right panel and click

on that the security group wizard one,

and it will pop up and showing you the entry of

the security group and right there in the second entry,

there is an ID start with SG.

SG is a shorthand notation for security group,

SG followed by some number.

Copy that down. That's what we're going to use.

Know that we also need some key, the key,

the private key to start this instance so that they can be printed into the.SSX command.

So the command for the easy to run instance is AWS EC2 run-instance,

and the first option here is the image ID.

We actually use copy from our own AWI image,

the ID and then we copy from

our instance security group ID and

the option code can allow us to specify

how many instance we are going to copy from this particular image.

Actually, you can actually simultaneously making

multiple instances in the case of constructing lower panel [inaudible].

If you have five instance from the same image you can actually specify [inaudible].

An instance take, we can specify what is the size of the computation size of the image is

a T2 Michael or M4 medium or large and we also specify the key,

the private key, which we are going to use corresponding to the private key that will be

put in.ssx authorized key and we use dash dash key name as an option and

the one common mistake people will do is

they type in the whole file name even with.pn as a file extension.

Actually here we shouldn't put a.pn file extension,

just a leading part of the file name.

Okay, and the query string basically allows to retrieve

specific instant ID and return and

depending on how you specify in your configuration step,

it can be written as a text,

can be a table or can be a JSON object.

To find a new instance, just create it.

We can using the command AWS EC2 describe-instance.

It will then put any option you will be basically listing

all the instance we already have in the particular default region,

in our case is Ohio.

From this information, if you're searching through it,

you can look for the instance ID and you'll find out one of

them is the new one and it was a 3d7.

On the EC2 dashboard,

there's also- we can see it in the management console there is no name tag.

Now the question becomes how can

we add a name tag so that we can distinguish these particular instance.

It turn out there's AWS EC2 create tag.

Okay. Once we create the instance we can then go back using

these create tag command to put the name in

place so that in the dashboard other operator can

see the actual name and instant name and we specify the instance ID,

but not using instance ID with s,

we are using the option code dash dash resources.

Somehow these AWS, they are naming to mention

this sometime mix up they try to use

a previous conversion and so it's not very consistent.

Also there should be no space between the last option which is key value pair.

So key equal the name,

comma no space, you need to say value equal,

whatever the value of that name and

name can be have entry attribute where you has a space,

you use a double quote to wrap around that.

To associate an elastic IP address with instance,

we also have equipment AWS EC CRI command.

First we need to find out where is the elastic IP address,

their allocation ID, the unique ID identified.

So everything go by the ID in AWS CRI.

We then use AWS EC2 associate-address.

That's a command, to associate elastic IP address with the instance.

You can verify the result by typing

the SSX to the instance with that elastic idea address

or check the associations in the EC2 management console and then you can verify

in that particular instance is now combined with

that IP address and you are successful be able to log in.
