Please go to page 35 of your textbook. Pick one of the problems presented on the middle of the page and write a short two-page paper about this topic, citing at least one major IT magazine or academic review. Focus on addressing the assignment statement at the end of the question. I am not interested in merely a 'book report', but your short analysis of the issue/problem the book wishes you to address. Thanks.

Please remember this needs to be in your words. No cut and paste, No turning in other's work. Any similarity scores of 30 or more will not be graded.

  1. Do some online research on the characteristics of software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS). Write a short paper describing the differences between these services and identifying some of the major providers of each type.
  2. Find and view several YouTube videos on unified communications. Identify the URLs for three that you think do a particularly good job illustrating the characteristics and capabilities of UC systems. Select the one that you think is best and briefly justify your selection.
  3. Do some online research to find information on several businesses that have benefited from implementing unified communications. Write a short paper describing how/why they are using unified communications and the business benefits that they have realized.
  4. Do some online research to find information on several businesses that have implemented IPTV. Write a short paper describing how/why they are using IPTV and the business benefits that they have realized.
  5. Do some online research on MANs and Metro Ethernet. Write a short paper comparing Metro Ethernet to other MAN alternatives that are available for business use.
  6. Use Skype, Yahoo Instant Messenger, or a similar tool that combines real-time voice, video (Webcam), and chat to establish a communication session with a friend or family member. Use one or more screen captures to document the convergence of voice, video, and chat for the communication session and paste these to a word processing document in a format (such as .rtf or .docx) that can be opened by your instructor. Your screen capture(s) should include Webcam windows for yourself and your friend/family member and a window illustrating your real-time chat.

In the evolving landscape of information technology, cloud computing services have significantly transformed how businesses and individuals access and utilize digital resources. Among the various service models—Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS)—each offers unique capabilities and caters to different operational needs. Understanding these distinctions is crucial for selecting appropriate solutions that align with organizational goals, cost efficiencies, and technological advancements.

SaaS is characterized by cloud-hosted applications accessible via web browsers, with the service provider responsible for maintenance, security, and infrastructure. Users typically subscribe to SaaS applications, which include popular tools like Salesforce, Google Workspace, and Microsoft Office 365. The primary advantage of SaaS is its ease of use and scalability, requiring minimal setup and maintenance from end-users (Marston et al., 2011). Major providers like Salesforce, Google, and Microsoft dominate this space, offering comprehensive SaaS solutions that cater to diverse business needs.

In contrast, PaaS provides a platform environment for developers to build, deploy, and manage applications without the complexity of underlying infrastructure. PaaS offerings include services like Google App Engine, Microsoft Azure, and Heroku, which supply frameworks, runtime environments, and development tools. The key benefit is accelerated application development and deployment, allowing organizations to focus on software innovation rather than infrastructure provisioning (Fu, 2017). These platforms support scalable, adaptable applications that can be integrated with various cloud services.

IaaS differs significantly by providing virtualized computing resources—servers, storage, networks—on demand (Mell & Grance, 2011). Organizations utilizing IaaS, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform, retain control over operating systems and applications, while cloud providers manage hardware maintenance. IaaS offers maximum flexibility and is suitable for organizations with dynamic workloads requiring customizable infrastructure solutions, such as hosting complex applications or developing scalable environments.

The major providers exemplify these models through their extensive portfolios: AWS and Azure for IaaS, Salesforce and Google for SaaS, and Google App Engine or Heroku for PaaS. Adoption of these services allows organizations to optimize costs, improve scalability, and accelerate innovation. For instance, a startup might leverage SaaS productivity tools to reduce IT overhead, while a large enterprise may deploy IaaS for scalable cloud hosting of critical applications. The choice among SaaS, PaaS, and IaaS depends on organizational needs, technical expertise, and strategic goals.
