Organizations can quickly scale up or down based on their needs without needing to invest in physical hardware or infrastructure. This flexibility allows businesses to respond rapidly to changing workloads, making it an attractive option for companies experiencing fluctuating demands or seasonal spikes in usage.
• Evaluate the potential risks and benefits of utilizing public cloud services for sensitive data storage.
  • Utilizing public cloud services for sensitive data storage presents both risks and benefits. On the benefit side, public clouds offer advanced security features and compliance certifications that can protect data. However, risks include potential data breaches and loss of control over sensitive information since it is stored on third-party servers. Organizations must carefully assess these factors and implement robust security measures and policies when considering public cloud storage for sensitive data.
• Assess the impact of public cloud adoption on traditional IT infrastructures and business operations.
