The key layers of cloud architecture include:
- Cloud Controller
- Walrus
- Cluster Controller
- Storage Controller
- Node Controller
Each layer plays a critical role in managing cloud resources and services.
18. What Is the Private Cloud Model?
A private cloud is a cloud infrastructure dedicated exclusively to a single organization, offering more control and security for sensitive data.
19. What Is the Public Cloud Model?
The public cloud model is a cloud computing model where services are provided to the public by third-party providers and are usually free or low-cost for users.
20. What Is the Hybrid Cloud Model?
The hybrid cloud model combines both private and public clouds, allowing organizations to move data and applications between the two environments based on their specific needs and requirements.
