Please read the attached "AWS Cloud Migration Project" word document for details on things required.
"Project_AWS_PoC_Cloud_Migration" word document includes steps, labs and required executive summary.
Project: Build Proof of Concept for BallotOnline Cloud Migration
In previous projects, you have investigated and reported on several aspects of cloud technology crucial to BallotOnline's cloud migration. To make a final determination, you have been asked to build a proof of concept for migrating the company’s website to Amazon Web Services' (AWS) cloud.
You will conduct the proof of concept in several steps.
1. You will build an AWS migration environment and configure web services needed.
2. You will test the migration environment.
3. You will prepare a cloud monitoring dashboard.
4. You will cause site outages and investigate the results on the monitoring dashboard.
In each of these steps, you will prepare lab reports documenting your efforts with the report templates provided.
Finally, you will prepare and submit the final Proof of Concept report.
STEP 1: Build an AWS Migration Environment and Configure the Web Services
The BallotOnline management has asked you to build out an environment as a proof of concept on Amazon Web Services (AWS) to migrate the BallotOnline web service. This environment will consist of virtual servers or virtual machines made up of two instances of EC2 that will both be used to serve out the BallotOnline website.
You will use AWS Elastic Load Balancer to split the traffic going to this site (so each of the EC2 instance will serve half of the Internet traffic) and you will also use AWS Auto Scaling to ensure that the servers can scale to support the demand. (In our specific instance, we want to make sure if one of the servers is down, a new instance will automatically be spun up.)
After the basic infrastructure is provisioned, then you will configure the web servers to be able to provide web services.
Lab 1: Build AWS Migration Environment Lab
Overview
In this lab, you will set up the core infrastructure. This includes your virtual machines (or instances)
in AWS Elastic Compute Cloud (EC2), Auto-Scaling group, and Elastic Load Balancer.
Log In to the AWS Console
• Log in to your AWS Academy Classroom.
• Click on the AWS Console button.
Launch an Instance
1. In the AWS services search box, type the following and hit Return or Enter on the keyboard to
access the Amazon Elastic Compute Cloud (Amazon EC2) web service. Alternatively, you can also access ec2 by clicking on the Services link (on the upper left corner of the screen) and selecting EC2 from the list of services.
2. On the Resources screen, under Launch Instance, click Launch instance.

AMI for that AMI, and manually choose the t2.micro instance
type.
Make sure you check “Enable EC2 instance detailed monitoring within CloudWatch” in the
Monitoring section, and select “Create a new security group” in Security Group section (note
the security group name), as well as your existing key pair in Key Pairs (login) section.
10. If you don’t have an existing keypair, in the Select an Existing Key Pair or Create a New
Key Pair box, select "Create a new key pair." For the key pair name, enter:
Lab625-key
Click the Download Key Pair button.
Save this private key file in a secure and accessible location on your computer. You will not
be able to download it again from Amazon. You will need this key for future lab activities in
LAB 625. Do not share this key file with anyone else since it will permit that person to
manage your Amazon instances.
Save the key as the following file name on your computer:
Lab625-key.pem
11. Accept all other defaults, check the acknowledgement at the bottom, and click Create
Launch Configuration
12. You will be kicked out to your Launch Configuration console, in which you can select your
launch configuration and click on Create Auto Scaling Group in Actions drop-down.

45. Under Instances, locate the Public IP Address for your instances.
EXAMPLE: 64.23.23.43
STEP 2: Test Web Services Migration
In the previous step, you built out infrastructure on AWS as a proof of concept to support BallotOnline's website.
Now, you will configure the EC2 instances with NGIX, a widely used web service and test the migration of the BallotOnline web site to these EC2 instances.
BallotOnline is concerned about performing an actual migration, so you will instead deploy the company's website code to the web servers that you configured in the previous step. The current webmaster of the BallotOnline website has provided you with the files to migrate to AWS.
Lab 2: Web Services Test Migration Lab
Overview
In this lab, you will configure the new BallotOnline web servers and migrate the BallotOnline website. You will build out new web services on each of your AWS EC2 instances and migrate the BallotOnline website to them.
After you complete this lab, you will have two web server instances behind a load balancer with auto-scaling enabled. This permits the website to remain available even if one of your instances is down for maintenance.
Connect to Your Instances
1. Log in to your AWS Academy.
2. Go to your LAB 625 classroom.
3. Click on the AWS Console button and go to EC2 (Amazon Elastic Compute Cloud).
4. Click on the Instances link on the left side of the screen.
5. Click the checkbox to the left of your first instance and then click the Connect button above your instance list.
6. You will see a screen that enables you to connect to your instance either using a Java SSH client or a standalone SSH client. For this step, you will follow the instructions provided by Amazon for your specific instance. If you are on a pre-Windows 10 computer, you will use PuTTY. If you are on a Windows 10, Mac or Linux computer, you will use the built-in SSH command.
Below are the specific instructions to use PuTTY to connect to your EC2 instance from a pre-Windows 10 system.
Download PuTTY (pre-Windows 10) or Use SSH (Windows 10/Linux/Mac OS)
7. Here, your instructions will vary depending on your operating system. If you are using Windows, follow the steps for installing PuTTY. If you are using Mac or Linux, follow the instructions for using SSH on Mac or Linux. Click the left side of the panel for Windows PuTTY instructions or Mac or Linux SSH instructions. If you are using Windows prior to Version 10, follow the steps for installing PuTTY. If you are using Windows 10, Mac, or Linux, follow the instructions for using SSH on Windows 10, Mac or Linux.
Installing Security Updates
8. If you get prompted to install security updates, do so by typing:
sudo yum update
The instructions are for updating the yum installer. The sudo command is used to perform the update as a superuser.
Whenever you are entering commands, pay close attention to the spelling and spacing. If you get error messages, it’s probably because the command is not typed correctly.
Notice that there are spaces between commands. We typed sudo [space] yum [space] update.
9. You will get a confirmation prompt. Type the following:
y
and press Enter.
When the installation is complete, you will see "Complete!” on the screen as shown below.
A screenshot of ec2 shell showing "Complete!"
Once the yum installer is updated, you will install nginx, which is a web server software for Linux.
Install nginx
10. Install the nginx web server on the instance. To do this, type the following in the command line:
sudo amazon-linux-extras install nginx1
Then, press Enter or Return.
11. You will be prompted with: Is this ok [y/d/N]:
Again, enter the following in the command line:
y
Then, press Enter or Return.
Upon successful completion of the installation, you will again see “Complete!” on the screen. If you did not get this, double check your commands to make sure you have typed them in correctly.
12. Create a directory for the BallotOnline website data:
sudo mkdir –p /data/www
Press Enter or Return.
13. Copy the BallotOnline website from the legacy BallotOnline website URL. First, you will switch to the directory that you just created:
cd /data/www
14. Next, you will download the website files from the legacy web server. The files have been compressed into website.zip and the URL is www.ballotonline.biz/website.zip.
Enter the following in the command line and then press Enter or Return.
sudo wget www.ballotonline.biz/website.zip
15. Now, you will unzip the file into the /data/www/BallotOnline directory.
Enter the following in the command line and then press Enter or Return.
sudo unzip website.zip -d /data/www/BallotOnline
16. Check to make sure that the website files were downloaded to the /data/www/BallotOnline directory by entering the following in the command line and then pressing Enter or Return.
cat /data/www/BallotOnline/index.html
You now should see html code similar to the screen below, starting with <!DOCTYPE html>
A screenshot of the content of the index.html file.
Update Website Permissions
17. Change the permissions on the website files to make them less restrictive by entering the following in the command line and then pressing Enter or Return.
sudo chmod -R 755 /data/www/BallotOnline
Replace the default nginx configuration file (located in /etc/nginx/nginx.conf) with the one that is provided within the zip file that you have downloaded and unzipped.
Enter the following in the command line and then press Enter or Return.
sudo mv /etc/nginx/nginx.conf /etc/nginx/nginx.conf.old
You can confirm that the nginx.conf is no longer there by typing this command and then pressing Enter or Return.
cat /etc/nginx/nginx.conf
Note: You should receive an error "No such file or directory"
18. For the next line, you will copy the nginx.conf that we have downloaded as part of the website.zip file to the correct location.
Enter the following in the command line and then press Enter or Return.
sudo cp /data/www/BallotOnline/nginx.conf /etc/nginx/
You should now have a file named nginx.conf in the /etc/nginx directory.
To double-check, type the following in the command line and then press Enter or Return.
cat /etc/nginx/nginx.conf
You should see the content of nginx.conf from the /etc/nginx directory.
19. Start nginx by entering the following in the command line and then press Enter or Return.
sudo nginx
Note: If you already started nginx for some reason, then you must reload the configuration with: sudo nginx –s reload.
Test the Web Server
20. Go to the Public IP Address for Instance 1 that is in your lab report via a web browser to see if you can access the index.html file:
http://NN.NN.NN.NN/index.html
21.After you've made sure your instance is configured correctly and serves the BallotOnline web page, you will create the AMI (Amazon Machine Image) from the instance.
In the Instances list of the EC2 service dashboard, select your instance, and then click on Actions – Images and Templates – Create Image.
In the Create Image screen, put in a name of LAB 625 P3 Web Server Image, and click Create Image at the bottom. Your image will be created. You can verify it by clicking on AMI under Images on the left in the dashboard.
22. In AWS Academy student accounts, instances are stopped when your session ends. If an instance belongs to an auto-scaling group, the auto-scaling service will mark the stopped instance as Unhealthy, remove it from the group, terminate it, and provision a new instance in its place (in our case, using the Launch Configuration created in Project 3 Step 1 with plain Linux image, without nginx and the BallotOnline website installed).
To remedy this, you will create a new Launch Configuration specifying the AMI created above and starting nginx upon initial instance launch. You will then update your auto-scaling group so that it uses the new launch configuration
In the EC2 dashboard, under Auto Scaling, click on Launch Configurations, and then on Create Launch Configuration. Give it a name like LAB 625 Lab New, and for Amazon Machine Image drop down the list and select your newly created LAB 625 P3 Web Server Image. You should find it among Owned By Me images.
For Instance Type, select t2.micro, as before. Under Additional Configuration – Optional, check the box to enable Enable EC2 instance detailed monitoring with CloudWatch. Then, in the drop down Advanced details, and under User Data, click on As Text and enter the following two lines in the box:
screenshot of text entered into the User Data box (with the "As text" option selected) that reads #!/bin/bash on the first line and nginx on the second line
Source: Amazon
This will ensure nginx is started up at each instance launch. User Data commands are run as a super user, so no need for sudo. See User Data for more information.
Scroll down to Security Groups, click on Select an Existing Security Group, and choose the auto-scaling security group you created in Project 3 Step 1, with SSH and HTTP inbound rules.
For key pair, select again your key pair you created in Step 1 of Project 3, making sure you have the private key file (.pem) handy. Double check everything. Check the Acknowledgement at the bottom, and then click on Create Launch Configuration. Verify that it shows in the Launch Configurations list under Auto Scaling.
Step 3: Prepare a Test-Environment Monitoring Dashboard
In this step, you will learn how AWS CloudWatch can be used to monitor system performance. You will create a CloudWatch dashboard in this step to monitor the resources in your test environment.
In addition to system performance, cloud users can also monitor their billing charges being accrued as cloud resources are provisioned and used. AWS provides a special set of metrics for monitoring billing charges, which can be used to set up a billing dashboard. You will not work with billing dashboards in this course, but it is worthwhile to know what they are and how to use them.
