8. Write examples of the following:
a. Government provided cloud computing platform
b. Large scale private cloud service providers and the services they provide
Ans. a. Government provided cloud computing platform: "GI Cloud" which has been named as 'MeghRaj' (https:// cloud.gov.in)
b. Amazon Web Services is a large-scale private cloud service providers and the services provided by them are infrastructures as a
service (IaaS), platform as a service (PaaS), and packaged software as a service (SaaS).
9. A company interested in cloud computing is looking for a provider who offers a set of basic services such as virtual server provisioning
and on-demand storage that can be combined into a platform for deploying and running customised applications. What type of cloud
computing model fits these requirements?
a. Platform as a Service
b. Software as a Service
c. Infrastructure as a Service
Ans. c. Infrastructure as a Service
10. Which is not one of the features of IoT devices?
a. Remotely controllable
b. Programmable
c. Can turn themselves off if necessary
d. All of the above
Ans. d. All of the above
11. If Government plans to make a smart school by applying IoT concepts, how can each of the following be implemented in order to
transform a school into IoT enabled smart school?
a. e-textbooks
b. Smart boards
c. Online tests
d. Wi-Fi sensors on classrooms doors
e. Sensors in buses to monitor their location
f. Wearables (watches or smart belts) for attendance monitoring
Ans. a. e-textbooks : e-textbooks can be made available e-library by using web services.
b. Smart Boards: Smart boards can be operated by digital stylus or pen and should be connected with network.
c. Online Tests: A web portal or online examination should be prepared to conduct exams smoothly.
d. Wifi sensors and classrooms doors: Wifi sensors and classroom doors can be used to lock and unlock them. These sensors also
provides security to students and other stakeholders.
e. Sensors in buses to monitor their location: These sensors enables quick reporting and monitoring to the coordinates and parents to
know the status of child and bus after leaving the school.
f. Wearables (watches or smart belts) for attendance monitoring: These devices can be used or implemented for students in such a way
that identifies a student and marks the attendance accordingly.
12. Five friends plan to try a startup. However, they have a limited budget and limited computer infrastructure. How can they avail the
benefits of cloud services to launch their startup?
Ans. Computer-based services are delivered over the Internet or the cloud, for the case of their accessibility from anywhere using any smart
device. The services comprise software, hardware (servers), databases, storage, etc. These resources are provided by companies called
cloud service providers and usually charge on pay per use basis.
There are three standard models to categorise different computing services delivered through cloud These are Infrastructure as a Service
(IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). services.
Infrastructure as a Service: The IaaS providers can offer different kinds of computing infrastructure, such as servers, virtual machines
(VM), storage and backup facility, network components, operating systems or any other hardware or software.
Platform as a Service: Through this service, a user can install and execute an application without worrying about the underlying
infrastructure and their setup. That is, PaaS provides a platform or environment to develop, test, and deliver software applications
Software as a Service: SaaS provides on-demand access to application software, usually requiring a licensing or subscription by the user.
A user is not concerned about installation or configuration of the software application as long as the required software is accessible.
The five friends who are planning to try a startup can choose from any of these. They can go for registration with any suitable service
provider either government or private. They can register for Infrastructure as a service to avail the facility of cloud storage and deploy
applications initially. Using IaaS, they can outsource the hardware and software on demand basis and pay as per the usage, thereby they
can save the cost of software, hardware and other infrastructures as well as the cost of setting up, maintenance and security.
