Using public cloud services presents several risks, including data breaches, compliance challenges, and the potential for service outages. Data stored in the cloud may be vulnerable to hacking or unauthorized access, raising concerns about privacy and security. Compliance with regulations, such as GDPR or HIPAA, can also become complex, as organizations need to ensure that cloud providers meet legal standards. Additionally, reliance on third-party providers means potential downtime can disrupt business operations. Organizations must carefully assess these risks before adopting public cloud solutions.
