COMPX527 Assignment

Objectives

The goal of this assignment is to give hands-on experience of using cloud services and how to design and deploy cloud-native applications. In order to achieve this objective, your cloud-based solution will be assessed based on these criteria:

• Deployment: How will your solution be deployed on AWS or cloud service provider of choice ?
• Automation: Is the deployment process automated or manual ?
• Reproduciblity: Can your solution be easily replicated or deployed elsewhere or by someone else ?
• Scalability: Has consideration been given to how to scale up or scale down your solution to meet increasing demand ?

You are expected to use tools like ansible,terraform and AWS CloudFormation to achieve these objectives. This will require that you get comfortable with the AWS CLI. See instructions below on installing AWS CLI and ansible to give you an idea of how to proceed with your assignment.

Getting started with AWS CLI and Ansible

The installation was performed on a Linux workstation, the instructions and commands might be different for other operating systems. Check the links below for instructions on how to install AWS CLI on Windows and MAC:

• https://docs.aws.amazon.com/cli/latest/userguide/install-windows.html
• https://docs.aws.amazon.com/cli/latest/userguide/install-macos.html

For linux:

• Install python3-pip

sudo apt-get install python3-pip

• Install a python virtual environment

pip3 install virtualenv

• Create a virtualenv for your project

virtualenv -p /usr/bin/python3 COMP527-ASSGMNT1

• Activate your virtualenv

source COMP527-ASSGMNT1/bin/activate

• Install AWS CLI inside your virtualenv

(COMP527-ASSGMNT1) root@ubuntu:~# pip3 install awscli

• Follow these instructions to generate AWS credentiails

• Configure AWS CLI with your AWS credentials to interact with AWS services via the command line.

(COMP527-ASSGMNT1) root@ubuntu:~# aws configure 
  AWS Access Key ID [None]: **********************
  AWS Secret Access Key [None]: ************************************** 
  Default region name [None]: us-east-1
  Default output format [None]: json

• Confirm your credentials work by creating and deleting test AWS s3 buckets for example

(COMP527-ASSGMNT1) root@ubuntu:~# aws s3 mb s3://comp527-assgnmt
(COMP527-ASSGMNT1) root@ubuntu:~# aws s3 rb s3://comp527-assgnmt

• Install ansible in the virtualenv to automate the deployment of your solution.

pip install ansible
pip install boto3
pip install botocore

• An example: ansible-playbook to deploy a simple website on s3. (remember to change your bucket name in the ansible playbook)

## Remember to change the bucket name and blog_root_dir in
## ansible-s3/roles/deploy-comp527-s3/defaults/main.yml to your own.
git clone git@github.com:olafayomi/COMPx527.git
cd COMPx527/ansible-s3
ansible-playbook main.yml --tags deploy-live-s3 

• Your website should be live at: http://your-bucket-name.live.s3-website-us-east-1.amazonaws.com/index.html)
