The Cloud Meaning
The cloud is a collection of many servers around the globe hooked together and meant to operate as a single ecosystem. These servers are designed to either store or manage data, run applications, or deliver content. They also store software. Instead of accessing files and data from a local or personal computer, you are accessing them online from any Internet-capable device - the information will be available anywhere you go and anytime you need it.
Cloud Security
Cloud security is a shared responsibility between the cloud provider and the customer. Cloud security can be responsible for the customer, the cloud provider or both. The top cloud providers have secure by design infrastructure and layered security that is built directly into the platform and its services, including multi-factor authentication and encryption.

Enhancements for an enterprise cloud environment include:
1. Password Hashing:
- Passwords are securely hashed using a strong hashing algorithm (in this case, `werkzeug.security.generate_password_hash`).
2. Role-Based Access Control (RBAC):
- Simulated user roles are introduced to control access to specific resources. In a real enterprise scenario, you might have a more sophisticated role management system.
3. Access Control:
- The `/api/protected` endpoint checks user roles to determine access permissions to specific resources.
4. User Data Storage:
- User data is simulated here, but in a production environment, you would store user information securely, possibly in a database or an identity management system.
