Waste management: IoT sensors can be used to monitor the fill level of waste bins and optimize waste collection
routes. This can help reduce the cost and environmental impact of waste.
Public safety: IoT sensors can be used to monitor public spaces for potential safety hazards, such as traffic accidents or
criminal activity. This data can be used to improve emergency response times and enhance public safety.
Water management: IoT sensors can be used to monitor water quality and usage in real time. This data can be used to
optimize water usage, detect leaks, and improve water conservation.
Overall, IoT is a key enabler of smart cities, offering new opportunities for data-driven decision-making and optimization
of urban services. However, it is important to ensure that appropriate safeguards are in place to protect the privacy
and security of citizens’ data. Further, it must be ensured that the benefits of smart city technologies are accessible to
all, including the underprivileged sections of society.
IoT is a key technology in the development of smart cities. IoT sensors can be used to collect data on a wide range
of urban services, including transportation, energy consumption, waste management, and public safety.
How can IOT help with smart transportaion in cities?
10.4 Cloud Computing
Cloud computing is a technology that allows users to access computing resources and services over the Internet,
without having to purchase them at their workplace. The companies that provide cloud computing services by
managing and operating the underlying infrastructure are known as cloud service providers. Cloud computing offers a
number of benefits over traditional on-premises computing, including:
Scalability: Depending on the requirements, the users may adapt to changing business needs and workload demands.
For example, they may add cloud computing (scale up and pay more), or relinquish resources (scale down and pay
less) quickly and easily.
Cost-effectiveness: Cloud computing services are typically charged on a pay-per-use basis, meaning users only pay for
the resources they consume, rather than investing in expensive hardware and infrastructure upfront.
Flexibility: Cloud computing services can be accessed from anywhere with an Internet connection, allowing users to
work remotely and collaborate with others in real time.
Reliability: Cloud service providers typically offer high levels of availability and uptime, as well as disaster recovery and
backup solutions, to ensure business continuity.
Next, we discuss three main cloud service models:
1. Infrastructure as a Service (IaaS): IaaS provides users with access to virtualized computing resources, such as
servers, storage, and networking, that can be used to build and deploy applications and services. With IaaS, users
are responsible for managing the operating system, middleware, and applications.
2. Platform as a Service (PaaS): PaaS provides users with a platform for building, deploying, and managing applications
without having to worry about the underlying infrastructure. With PaaS, users can focus on developing applications,
while the platform handles scaling, availability, and security.
3. Software as a Service (SaaS): This provides users with access to software applications and services, such as email,
CRM, and productivity tools, over the Internet. With SaaS, users simply access the application via a web browser
or app, and the cloud service provider manages all underlying infrastructure and maintenance.
