In this project, you will develop a detailed comparative analysis of cloud vendors and their services. A comparative analysis provides an item-by-item comparison of two or more alternatives, processes, products, or systems. In this case, you will compare the pros/cons of the cloud service providers in terms of security, ease of use, service models, services/tools they provide, pricing, technical support, cloud service providers’ infrastructure, and architecture model.

You will present your findings to the owner of the company in a narrated PowerPoint presentation with 10 to 20 slides. Use the Cloud Presentation Template.

This resource can help you prepare and record your presentation: Presentation Resources.

Presentation Guidelines

Your presentation should be comprised of the following:

• One to two slides on the company profile.
• One to two slides on what the company is struggling with.
• One to two slides on current infrastructure.
• Three to six slides on the top three cloud services providers. Include their service models (i.e., SaaS, PaaS, IaaS), services/tools/solutions (i.e., compute, storage, database, developer tools, analytics tools, networking and content delivery, customer engagement), pricing, accessibility, technical support for companies, global infrastructure.
• One to two slides on a recommended cloud service provider based on the comparative analysis and the cloud vendor’s abilities to meet the service needs of the company.
• One slide on the conclusion.

 Discuss whether internal security audits are enough for an organization or do they need to perform external audits as well. Also discuss in which scenarios the external audits are mandatory to perform. 

Assignment Objectives:  Choose an Alert closely related to the weekly topic and write a concise summary using the template.

Assignment Directions: 

1.  The US Government Cybersecurity & Infrastructure Security Agency (CISA) provides timely notification to critical infrastructure owners and operators concerning threats to critical infrastructure networks. Each week, review the National Cyber Awareness System website.   
2.  Choose a topic closely related to our weekly material and write a concise summary using the organizational template and example
