COSC2737 Assignment 2: IT Infrastructure in the Cloud

COSC2737 Assignment 2: IT Infrastructure in the Cloud. In this assignment, you will combine 3 different cloud services to build an application of your choice. Typically, this might include a web-facing component. The focus of the assignment is not this content, but the infrastructure behind it – the “wiring”, if you will. As part of the assignment, you will create a presentation video.

If this is done well, you will be able to add these to a portfolio of work that you can demonstrate at job interviews, etc. NB. This assignment is focused on Amazon products, primarily because that is what we teach in ITIS, but you are also allowed to use Google or Microsoft products, or a combination – but only with prior permission from the Course Coordinator. And we may not be able to help you if problems between vendor products arise.

For this assignment, you will provide a simple working cloud implementation, and submit the contents in a ZIP file to Canvas, along with a presentation video, a report, and an initial PDF “pitch” document submitted some weeks earlier than the deadline.

Note that the web content itself is not evaluated, only how it is set up. So you can use material from anywhere (as long as you cite it on the web pages). List of Amazon Services: List of Amazon services available to AWS Educate: services/AWS_Educate_Starter_Accounts_and_AWS_Services.pdf also available on Canvas.

Build a Cloud Infrastructure Using at Least 3 Components

Your task is to build a cloud infrastructure using at least three components from the AWS list of products. This could involve servers, storage, compute resources, or other services. One of the components could be Amazon Alexa services for query handling. The web application should have at least five pages and be of a B2B nature.

Submission Components

1. Pitch Document

This is an initial “pitch” where you describe your proposal in a few paragraphs (not more than a page). It is due in week 11 and will inform feedback from your tutor.

2. Report

The report should be a PDF containing:

  • Rationale: the reasoning behind your website and cloud setup (a refined version of your pitch).
  • Cost Estimates: including development, fixed, and cloud operational costs. Provide estimates for LOW (1-1,000 transactions/day), MEDIUM (1,000-1,000,000), and HIGH (more than 1,000,000+). Justify all costs.
  • Installation Manual: detailed instructions that enable someone to recreate your cloud setup.

The report should be about 10-15 pages, including figures and screenshots.

3. Content

A ZIP file containing all user and generated content, not exceeding 10MB. The installation guide should enable reproducing the setup.

4. Presentation Video

A video demonstration of your application, included in the ZIP or linked in the report. Maximum length: 10 minutes, aim for less.

Additional Notes

The assignment deadline is at the end of week 11 for the pitch and start of week 14 for the full submission (content, video, report). It is an individual assignment worth 30% of the semester grade. Highlight any obvious features like scalability in your report for clarity.

Summary

The focus is on demonstrating a concrete cloud infrastructure, not on the content hosted or webpage design. Use credible references and be comprehensive in your technical documentation. The final deliverables should showcase your understanding of cloud architecture, cost management, and deployment procedures.

Building a Cloud-Based Application Using AWS Services: Infrastructure Design, Implementation, and Cost Analysis

Introduction

The rapid expansion of cloud computing services has transformed how organizations deploy and manage applications. This paper examines the process of designing, implementing, and analyzing a cloud infrastructure on Amazon Web Services (AWS), emphasizing a multi-component setup aligned with the assignment's guidelines. The goal is to demonstrate an effective, scalable, and cost-efficient cloud environment capable of supporting a B2B web application with multiple pages and features.

Designing the Cloud Infrastructure

The foundation of the infrastructure involves selecting three core AWS services: Amazon EC2 for compute capacity, Amazon S3 for storage, and Amazon RDS for database management. Additional services include Amazon Route 53 for DNS management and Amazon Lex for conversational queries, aligning with the inclusion of Alexa-like services.

Component Selection and Justification
  • Amazon EC2: Provides virtual servers for hosting web applications. Its scalability supports varying load conditions, essential for a B2B platform.
  • Amazon S3: Offers reliable object storage for web assets, documents, and other static content, ensuring availability and durability.
  • Amazon RDS: Manages relational databases, supporting dynamic data storage requirements for user data and transactions.
  • Amazon Lex: Enables natural language understanding for query handling, enriching user interaction capabilities.

Application Architecture

The web application architecture comprises multiple pages (home, products, services, contact, and user dashboard), interlinked via Amazon Route 53. User requests are routed to EC2 instances hosting the web servers, which interact with RDS for data and S3 for static content. Lex integration facilitates user query processing, providing a conversational interface.

Implementation Challenges and Solutions

Deploying a multi-service architecture requires careful configuration of security groups, VPCs, and IAM roles. Ensuring seamless integration between services involved setting up API gateways and Lambda functions to mediate interactions, especially with Lex services. Authentication and access control were managed through AWS Identity and Access Management (IAM).

Cost Estimation and Scaling

Cost estimates were derived based on AWS pricing models, considering development and operational costs across three transaction levels. For low activity (1,000 transactions/day), monthly costs total approximately $50; medium activity (1 million transactions), around $500; and high activity, exceeding $1,500. These estimates include EC2 instance hours, storage, database usage, and Lex query costs, providing a scalable financial plan.

Installation Manual

  1. Create an AWS account and set up a VPC for network segmentation.
  2. Launch EC2 instances with appropriate security groups and install necessary web server software.
  3. Configure Amazon S3 buckets for static content hosting.
  4. Set up Amazon RDS instances with the target database engine and schema.
  5. Configure Amazon Route 53 to route domain traffic to EC2 instances.
  6. Integrate Amazon Lex for query handling by creating bots and linking them with web interfaces via Lambda functions.
  7. Implement IAM policies for secure access management across services.
  8. Test the entire setup to ensure interoperability and responsiveness.

Conclusion

This multi-component AWS architecture demonstrates how scalable, reliable, and secure cloud infrastructure can support a B2B web application. Cost analysis confirms the feasibility for different transaction volumes, and a detailed installation guide ensures replicability by others.
