CLOUD COMPUTING

Company Profile:

$$

RAALI is an organization with $7000$ employees and more than $2$ million customers

$$

The organization operates two data centers in different regions

Business applications run on more than $300$ physical compute systems

Some of the applications are proprietary

Infrastructure resources are heterogeneous

Organization$$s Challenges

$$

Coping with fast$-$changing customer demands

Rapid development and deployment are very difficult with the current infrastructure.

Utilization of the infrastructure resources is less than $25\%$

Currently, each server is utilized by a single OS and the applications are deployed on the single OS$.$ On Average, each server's resource utilization is between $20$ to $30$ percent

The storage resources are reserved with a specific capacity for applications, which creates a lack of storage utilization as many applications were only using less than $15\%$ of the allocated storage.

New application deployment takes some time as it involves Purchasing a new compute server, storage, Installing the OS and software, Configuring the network and storage, Configuring security

Questions:

$$

A$.$ Explain to RAALI how they can improve the utilization of the compute resources.

$$

B$.$ What is the name of the software that is installed on a compute system and enables multiple OSs to run concurrently on a physical compute system? Describe the two main components that exist in that software.

$$

C$.$ Describe a storage technique discussed in the virtualization layers that enables the creation of storage volumes based on the host demand and increases as the demand increases up to the max number of requested capacity. Discuss clearly how the technique can help RAALI in their challenges.

$$

D$.$ Describe a way that allows RAALI with the ability to serve requests that require proprietary software with specific VM capability in a minimal amount of time.

$$

E$.$ Describe to the organization how they can transform their data centers to a cloud$-$based data center.

$$

F$.$ What is the cloud deployment model that is adopted in this case after converting their infrastructure to cloud? Explain.
