Cloud computing

Definition

Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, and analytics—over the internet, or 'the cloud.' This model allows users to access and store data remotely, providing flexibility, scalability, and cost efficiency, which greatly impacts how businesses manage their IT resources.

Review Questions

• How does cloud computing facilitate real-time collaboration among users?
  • Cloud computing allows users to access shared applications and data stored on remote servers over the internet. This means that multiple users can work on the same project simultaneously from different locations, enabling seamless collaboration. Features like document sharing and version control make it easy for teams to stay in sync and improve productivity.
• Discuss the impact of cloud computing on disaster recovery and business continuity plans.
  • Cloud computing significantly enhances disaster recovery strategies by enabling data backups to be stored off-site in secure locations. In case of hardware failure or data loss, businesses can quickly restore their operations using the cloud's remote resources. This capability not only minimizes downtime but also ensures that critical business information is protected against various threats.
• Evaluate the challenges businesses might face when adopting cloud computing and how they can mitigate these risks.
  • While cloud computing offers numerous benefits like cost savings and scalability, businesses may encounter challenges such as data security concerns and compliance with regulations. To mitigate these risks, companies should implement strong cybersecurity measures, including encryption and access controls, and conduct thorough assessments of potential cloud providers. Additionally, maintaining clear communication regarding data handling policies can help ensure compliance with industry standards.
