42904 CLOUD COMPUTING AND SOFTWARE AS A SERVICE ASSIGNMENT 3

Team/Group Registration :

This is an individual assessment item. You are required to complete this assignment on your own. This assignment also requires a bit of independent research to complete it. You are required to do this on your own and complete it.

Assignment Description :

Imagine that you meet with a small startup company that is in the early stages of its operations. Currently, their architecture uses a LAMP stack (with MySQL), Apache and PHP all running on one desktop PC within their small office.

Like many  small  startups,  they  are confident they will be the next big thing  and  expect significant, rapid, yet un-quantified growth in the next few months. With this in mind, they would like you to architect their system and develop it in AWS. The startup is concerned with the following requirements:

(a) They would like the developed application to scale up on demand. With uncertainty around when and how much the demand would be, they are concerned about buying too much infrastructure too soon or not enough infrastructure.

(b) They want to cater to disaster recovery to ensure high performance and throughput of their application.

Objective:

Design  and implement  a scalable,  elastic, highly  available,  fault-tolerant  architecture that allows  the  startup  to  grow  organically.  The  architecture  should  specifically  address  the requirements/concerns listed in the description above.

Assignment Deliverables:

The deliverables of Assignment 3 are two-fold as below:

(a) Deliverable  1 (System architecture): A PDF document (no greater than four to five pages) clearly and succinctly outlines the proposed architecture diagram. Clearly justify the inclusion of all Amazon Web Services (AWS) services. Furthermore, please clearly outline all assumptions made during the design and explicitly state the AWS used in developing the solution. You are welcome to use any diagramming tool to draw the architecture of the system

(b) Deliverable  2  (AWS  solution):  Develop  the  application  in  AWS  using  the  AWS Educate account. You may choose either to use AWS Elastic Beanstalk to configure and deploy your application or configure  and  deploy  each  application  component individually using AWS services. You will need to use the following AWS Services.

a)  AWS Beanstalk

b)  Amazon EC2

c)   Custom AMI (Amazon Machine Image). (Please note that you are required to create your own custom AMI)

d)  Custom Security groups allowing HTTP and SSH requests (All instances must use the same custom Security Group)

e)   Load Balancer

f)   Auto Scaling (with a minimum of two instances and a maximum of eight instances).  Scaling  triggers  on  Network  output  traffic  with   an  Upper threshold of 60% lower threshold of 30%.

g)  RDS (Multi-Availability zones deployed)

h)  Custom Virtual Private Cloud (VPC) (with at least two subnets in different Availability Zones). All subnets must be public.

i)   All instances must use the same custom key pairs.

j)   Set email notifications for important events in your environment (if using Elastic Beanstalk)
