Why IaaS?
6
 New businesses can operate without investing on computer
hardware.
 Scalable for rapidly growing businesses. (Organizations that
experience huge success immediately)
 Suitable for serving fluctuating computing demands. (Ex. Flipkart,
Amazon during festival seasons)
 Suitable for new business model trials.
 Helps in minimizing the capital expenses. (entrepreneurs
starting on a shoestring budget)
4/28/2024

7
 Scalability and elasticity:
 Dynamic scaling of required infrastructure resources
 Large amount of resource allocation/release in a short
span of time
 No variation in system performance while scale in or out
4/28/2024

8
 Manageability and interoperability
 Clients have control of the virtualized infrastructure resources
 Pre-configured facility for allocation of virtualized
resources
 The virtualized resources are to be monitored for their running
status
 The Usage and Billing system records the use of
infrastructure resources and accordingly calculate
payment
4/28/2024

9
 Availability and reliability
 Stored data can be retrieved at any time without failure
 The clients should be able to access the computational
resources without failure
 Uninterrupted facility for computation and
communication
4/28/2024

10
 Performance and optimization
 High utilization of physical resources among different
clients

Virtualization Concept
8
 One computer host appears as many computers‐concept of Virtual
Machine (VM)
 Improve ITthroughput and costs by using physical resources as a pool
from which virtual resources can beallocated.
 Benefit
Sharing of resources: Same resource can be shared, in turn cost
reduction
Encapsulation:A complete computingenvironment
Independence: Runs independently of underlyinghardware
Portability: VM Migration

Limitations of WSNs

Case Study: Target Tracking
17
“We consider a WSN‐based target tracking application, in which a WSN owner
refuses to share the sensed information with an external body, even in exchange
of money. Consequently, any organization that wishes to detect intrusion within
a particular zone has to deploy its own WSN. This leads to a long‐term
investment due to costly network setup and maintenance overheads. However,
in a sensor‐cloud environment, the same organization can use the same tracking
applicationand stillget the service without actually owning theWSN”

Service Management in IIoT
 “Service management refers to the implementation and
managementof the quality of services which meets the
end‐users demand”
 “Serviceis a collection of data and associated behaviors to
accomplish a particular functionor featureof a device or
portions of a device”.

Service Management in IIoT
 Service canbe of two types,which are ‐
Primary service ‐The basic services which are
responsible for the primary node functions are termed
as primary service.
Secondary service ‐The auxiliary functions which
provide servicesto the primary service or secondary
services are termed as secondary service.

Applications ofIIoT
 The keyapplication areas of
IIoTare ‐
Manufacturing industry
Healthcare Serviceindustry
Transportation & logistics
Mining
Firefighting

Manufacturing Industry
3
 The devices, equipment, workforce, supply chain, work
platform are integrated and connected to achieve smart
production. This will led to –
reduction in operationalcosts
improvement in the productivity of theworker
reduction in the injuries at theworkplace
resource optimization and wastereduction
end‐to‐end automation.

Healthc are ServiceIndustry
 Patients can be continuously monitored due to the
implanted on‐body sensors. This has led to–
improved treatmentoutcome
costs hasreduced
improved diseasedetection
improved accuracy in the collection ofdata
improved drugs management.

Transportation & logistics
 Toimprove safety,efficiency of transportation,Intelligent
Transportation system (ITS) is developed which consists of
connected vehicles. ITS provides –
Vehicle – to – sensor connectivity
Vehicle – to – vehicle connectivity
Vehicle – to – internet connectivity
Vehicle – to – road infrastructure
 Dedicated short‐range communications (DSRC) is the key
enabling technologyforV2V andV2R communications.

Transportation & logistics
 In IIoTscenario thephysical objectsare providedwith
bar codes
RFID tags
hence, real‐time monitoring of the status and location of the
physical objects fromdestination to the origin, across the
supply chain is possible.
 Security and privacy of the datashould be maintained.

Mining
 Toprevent accidents inside the mines ‐RFID,Wi‐Fi and
other wireless technologies are used,which
provides early warning of anydisaster
monitors air‐quality
detects the presence of poisonous gases inside the
mines
oxygen level inside themines.

Firefighting
 Sensor networks, RFID tags are used to perform
automaticdiagnosis
 early warning ofdisaster
emergencyrescue
provides real‐timemonitoring Hence, improves public
security.

Examples of IIoT
9
 Examples of IIoT are‐
unmanned aerial vehicles (UAVs) to inspect oilpipelines.
monitoring food safety usingsensors.
minimizing workers’exposure to noise, chemicals and
otherhazardous gases.
unmanned marine vehiclewhich can collectdataup to a
year without fuel or crew.

Connected Ecosystems in IIoT
scenario
 Traditional supplychains in industries are linear in nature.
 Toshift the business focus from products to outcomes, new
ecosystem should befollowed.
 Digital ecosystems progress ata much faster ratethan
physical industries. Hence, itcan quickly adapt to the changes
in the external environments.

Integration of Digital and
Human Workforce
 In IIoT,machines become more intelligent.Hence, the
automatedtasks canbe done in the industries atlower costs
and higher quality level.
 Humans will work with machines, the outcome will be
higher overall productivity.
 IIoTwill reformand redefine the skills of the workers.

Creation of New Jobs
 The creation of new composite industries, such as precision
agriculture, digital healthcare system, digital mines etc., will
lead to developmentof new jobopportunities.
 Highly automated machines will require lesser number of
unskilled workers, but will require skilled experts with
digitaland analyticalskills.

Reformation of Robots
 In IIoTenvironment, robots are featured with three capabilities :sensing,
thinking and acting.They will be reformed with the ability to carry out
repetitivetasks.
 Robots will be more intelligent butwill work under the supervision of
human beings. Their availability willincrease.
 Robots will be reprogrammable toperform nasekws.t They havethe
capability to ‘learn’faster.

So there are chances of attackon the personal and privatedata.

Privacy and securityissues
 Examples –
Healthcare industry – the medical data of a patient
must not be tampered, or altered by any person in the
middle.
Food industry – the deterioration of any food item being
sent to the company must be kept confidential as it will
affectthe reputation of the company.

Risksassociated with IIoT in
Manufacturing
 Though IIoTprovides new opportunities, but few
factors may cause hindrance in the path tosuccess,
which are :
lackof vision andleadership
lackof understanding of values among management
employees
costly sensors
inadequate infrastructure.
