Review Questions

• How does cloud computing enhance collaboration in modern workplaces?
  • Cloud computing enhances collaboration by allowing multiple users to access shared documents and applications simultaneously from different locations. This facilitates real-time editing, communication, and project management, enabling teams to work together more effectively regardless of geographical barriers. The ability to store and share data in the cloud means that everyone has access to the most current information at any time.
• Discuss the security challenges associated with cloud computing and how they can be addressed.
  • Security challenges in cloud computing include data breaches, unauthorized access, and loss of control over sensitive information. To address these challenges, organizations can implement strong encryption methods for data both in transit and at rest, enforce strict access controls, and regularly monitor user activity for suspicious behavior. Additionally, choosing reputable cloud service providers who prioritize security measures can significantly mitigate risks.
• Evaluate the impact of cloud computing on traditional IT infrastructure and business models.
  • Cloud computing has profoundly impacted traditional IT infrastructure by shifting the focus from on-premises servers to scalable cloud solutions that reduce costs and increase agility. Businesses can now adopt subscription-based models instead of investing heavily in hardware and software upfront. This shift allows companies to innovate faster and respond to market demands more efficiently while also enabling startups to compete with established players by lowering entry barriers.
