Q2. To understand the functionality of Type 2 Hypervisor, download and install Oracle
VirtualBox. Before downloading read the documentation and write a ½ page summary on the
product. You can run a lightweight OS, such as Ubuntu in the VirtualBox or you can choose a
different OS. In addition, to your report, you need to provide a screenshot of the guest OS
terminal (with your name as the user) running on virtualized platform, and your system’s
host OS.

Q3. “ABC” company has launched a virtualized service (S) running on Virtual Server (V). For each
of the following scenarios, provide an appropriate solution with proper justification and
pictorial representation (if applicable).
a) “ABC” has 1000 users, and each user accesses the service approximately 1000 times
in an hour. Is “ABC’s” system sufficient to handle the requests? If not, then what are
the available options?
b) “ABC” has option to rent private cloud, which is little expensive. However, all the
customers use free tier of the service (S). Is it logical to rent private cloud? Provide
justification. Do you have any suggestion for “ABC”?

Q4. This question simulates a cloud computing architecture. You need to design a program using
a standard high level programming/scripting language, such as Java/Python etc.

“Cloud5409” is a reputed hypothetical cloud provider company, which has 100,000
customers. 50,000 customers use paid-private cloud accounts, 20,000 customers use
partially paid account with hybrid cloud model, and 30,000 customers use free-public cloud
accounts. Each paid user can send unlimited requests, and SLA states “Auto Scaling” is
available. Partially paid users’ SLA states “Auto Scaling” is possible only after 60% of the tasks
are performed. Resource pools can be created and used if applicable. This model does not use
any cloud bursting architecture.

a) Before designing the program, build the scenario. Write each step, and provide
graphical representation of the scenario
b) Write a program to simulate the scenario, and test it with different input/output. Your
program should simulate every step – e.g. placing input or requests, processing
requests, allocation/deallocation of resources, AutoScaling check, and executing any
intelligent script (if required).
c) Take screenshot of your outputs.
d) Your program does not have to produce graphical output.
e) Finally generate a graph of cloud resource usage for 1000 requests.
