Q7. Why Hybrid Clouds are so important?
Ans
Cloud Bursting:
Access capacity and specialized software are available in the public cloud and not in the private cloud.
Examples: Virtual Amazon and Dynamo
Leveraging the best of both worlds, there are hybrid clouds.
vCloud:
- It is a VMware cloud.
- It is expensive.
- It gives enterprise quality.
OpenStack:
- It has commodity servers and storage.
- It is less reliable.
- We can run web servers on OpenStack.
- the database is built on vCloud.
Q8. Mention the different types of models used for the deployment in Cloud Computing.
Ans
- Private Cloud
- Public Cloud
- Community Cloud
- Hybrid Cloud
Q9. Explain security management in terms of Cloud Computing.
Ans
- Identity management access provides the authorization of application services.
- Access control permission is given to users to have complete controlling access of another user who is entering into the cloud environment.
- Authentication and authorization provide permission to only the authorized and authenticated users to access the data and applications.
Q10. Which are the layers of Cloud Computing?
Ans
- CLC or Cloud Controller
- Walrus
- Cluster Controller
- Storage Controller (SC)
- Node Controller (NC)
