Storing data on public clouds like AWS or Azure has multiple challenges. I should note again that clients don$$t have control over public clouds. Due to this, I believe the biggest challenge is that a data breach or unauthorized access could compromise the entire cloud. And since AWS and Azure are public, they are open to more threats from hackers. mitigation strategy SUCH as implementing strong encryption protocols, and regularly updating access controls. Also consistently testing the security of the cloud to make sure everything is running smoothly. Companies can implement $$checksums$$ to verify data integrity. Checksums check data for errors. Also, ensuring high availability is essential to prevent downtime that could disrupt operations. Redundancy through data replication across multiple geographic regions and utilizing load balancing systems can avoid this risk.

To maintain confidentiality and availability, authentication methods, such as multi$-$factor authentication, should be enforced. Data backups and disaster recovery plans can help minimize the impact of potential issues. Lastly, continuous monitoring and timely response to security threats are essential pieces of a full data protection strategy in the cloud.
