Review Questions

• How does cloud computing facilitate collaboration among users in different locations?
  • Cloud computing enables collaboration by allowing users to access shared files and applications from any location with an internet connection. This means that team members can work together in real-time, regardless of where they are physically situated. The ability to update documents simultaneously and utilize communication tools integrated within cloud platforms enhances teamwork and productivity.
• Discuss the advantages of using Infrastructure as a Service (IaaS) in the context of cloud computing.
  • Infrastructure as a Service (IaaS) provides significant advantages in cloud computing, such as flexibility and scalability. Users can quickly provision virtual machines and storage without investing in physical hardware, which reduces capital expenditures. Additionally, IaaS allows businesses to scale their resources up or down based on demand, leading to optimized operational efficiency and cost savings.
• Evaluate the impact of cloud computing on data security practices within organizations.
  • Cloud computing has transformed data security practices by introducing advanced security measures like encryption, multi-factor authentication, and regular compliance updates. However, it also raises concerns about data breaches and loss of control over sensitive information since data is stored off-site. Organizations must adopt robust security protocols and understand their shared responsibility model with cloud providers to ensure effective protection of their data assets.
