In one of my University projects this year we are tasked with setting up a basic AWS infrastructure. Let's take a look at the questions and my answers with screenshots.

The Scenario:

Erfys Confection is pleased with your research and analysis of their current cloud requirements (Assignment 1). To fully commit to the cloud migration the board members would like to see a working proof of concept. Perform the following tasks to demonstrate the benefits of cloud adoption.

Task 1: List functions, benefits and differences of cloud services

After comparing the functions and benefits, list your recommended AWS services based on A1 Confectionary’s cloud service requirement and justify with reasons?

Vertical scaling or horizontal scaling
Virtual machines or Physical machines
Relational database or data warehouse or no SQL databases
self-hosted or managed or cloud-native database solutions
Block storage and object storage
archive storage and network filesystems storage

Task 2: Implement Cloud User

Accounts and restricted access

Below are the tasks you need to implement on your AWS account or LMS environment. For each step, you are required to provide a screenshot of each task.

Scenario: As a proof of concept before migration, your manager would like to see the implementation of cloud users and groups. The following new user accounts and groups have been created in the AWS account. You need to give access to new staff depending upon their job function:

Users

In Group

Permissions

user-1

S3-support

Read-Only access to Amazon s3

user-2

EC2-Support

Read-Only access to Amazon EC2

user-3

EC2-Admin

View, Start and Stop Amazon EC2 instances

Following the organisational requirements, complete the following tasks (Lab 1):

Add user-1 to the S3-support Group
Add user-2 to the EC2-Support Group
Add user-3 to the EC2-Admin Group
Test user access: Sign in as each user and test their access permissions
Check whether the default AWS Password policy is enabled or not

All users with the group assigned

All user accounts are to be logged in with the management console and their access permissions

User 1 logged in and showing S3 permissions

User 2 logged in to management console, viewing EC2 instances (there aren’t any to view here as this lab was started for purposes of completing this part of the assignment)

User 3 logged in

Task 3: Create AWS Virtual network and Security settings

As a proof of concept before migration, your manager would like to see a simulated environment to test all functions and features.

1. Implement a multi-tiered network capable of supporting auto scaling (Lab 2). See network diagram below (Fig.2):

You need to:

· Set up a VPC (Virtual Private Cloud) network

· Create one virtual network and inside the network create 2 public and 2 private networks.

· Assign Public/Private subnets to the related routing table associations based on requirements.

· Create a security group that only allows HTTP and HTTPS to access the public network.

Insert a screenshot showing the security group.

Insert the screenshot of routes for all your routing tables

2. Create virtual machines:

For test purposes, the ITWorks manager needs you to set up a virtual server according to the business requirements.

Configure the following (Lab 3):

· Launch a web server with termination protection enabled. Choose Amazon Linux as the Operating system (Choose Free tier eligible option, for example, t2.micro or t3.micro).

· Monitor Your EC2 instance

· Modify the security group that your web server is using to allow HTTP access

· Test your HTTP access from your home/class PC and take screenshots.

Insert your screenshots below:

EC2 console with public IP address and availability zone

Security Groups with rules allow HTTP and HTTP

Successful web access page from your computer

3. Add additional storage and make storage expandable.

Erfys Confectionary wish to test storage functionality.

Conduct the below tasks (Lab 4):

· Create an Amazon EBS volume

· Attach and mount your volume to an EC2 instance

· Resize the EBS Volume: Increase the EBS storage size from 1 GB to 10 GB

Insert the following screenshots:

EBS page

(screen shot taken after volume resized)

EC2 instance page

df –h result in Linux CLI

EBS storage resize page (from 1GiB to 10GiB)

4. Erfys Confectionary wish to implement a highly available database. Perform the following tasks (Lab 5):

· Launch an Amazon RDS DB instance with high availability across 2 different availability zones.

· Configure the DB instance to permit connections from your web server.

· Open a web application and link to your database.

Insert the following screenshots:

Network DB security group.

Database Subnet Group

Database creation

The website successfully connects to Database (Showing address book)

5. Complete the troubleshooting table below:

Task 4: Deployment of automatic scaling

In this task, you need to configure and apply auto-scaling to the virtual machine according to the Cloud requirements section of the organisational requirements. Once it is configured, you need to test and fix errors faced in the autoscaling.
