Review Questions

• Explain how the SaaS model differs from traditional software deployment in terms of infrastructure management and cost.
  • In the traditional software deployment model, organizations would need to purchase, install, and maintain the hardware and software infrastructure to run their applications. This often required significant upfront investments and ongoing maintenance costs. In contrast, the SaaS model shifts the infrastructure management responsibilities to the service provider, allowing organizations to access the software through the internet without the need to manage the underlying infrastructure. SaaS also typically offers a subscription-based pricing model, which can provide more flexibility and scalability compared to the traditional perpetual licensing approach.
• Analyze the potential benefits and challenges of the SaaS model for organizations in the context of their external environment.
  • The SaaS model can provide several benefits for organizations in their external environment. By outsourcing the management of software applications, organizations can focus on their core business activities and reduce the burden of IT infrastructure management. SaaS also offers scalability, allowing organizations to easily adjust their usage and costs as their needs change. Additionally, SaaS can improve accessibility and collaboration, as users can access the software from anywhere with an internet connection. However, the SaaS model also presents some challenges, such as concerns about data security and privacy, as well as potential vendor lock-in and dependency on the service provider's reliability and stability.
• Evaluate how the adoption of SaaS can impact an organization's ability to respond to changes in its external environment, such as technological advancements, competitive pressures, or regulatory requirements.
