Abstract
Smart Home systems are systems through which any home, business or process in the
industry can be controlled remotely via a mobile device via a secure internet connection.
At any given time, Smart Home devices download data and store it either in personal storage
or in one of three types of cloud structures: private cloud, public or hybrid cloud.
The choice of how to store this data is strictly individual and depends on the confidentiality
and criticality of the recorded data.
This article gives the advantages and disadvantages of storing data from Smart Home devices
in different types of clouds and personal storage.
Keywords:
Smart Home, smart devices, lighting, heating, security, security, personal storage, private
cloud, public cloud, hybrid cloud.
1.Introduction
Nowadays, the life of mankind is unthinkable without the Internet. It is a global network through
which full connectivity and communication is achieved regardless of distance, time and physical
ability. The Internet of Things is a natural continuation of the development of this process. It is a
platform that seeks to bring all services, systems and devices together. All this is in order to achieve
through the use of information technology maximum comfort and efficiency of our environment.
Every home uses high technology, which serves both for entertainment and to achieve comfort in
our way of life. In the fast-paced everyday life, the increasing employment of people and the desire to
save energy in order to protect the planet, the desire to manage the home remotely and the resources
used for this leads to the entry of the Smart Home system - or Smart Home.
Smart home appliances include technology that can automate and control security, air
conditioning, heating and ventilation, and that can extend to household appliances such as
dishwashers, dryers and refrigerators. This technology is becoming increasingly popular.
All sensors and sensors that are part of the Smart Home system, in addition to feeding data to the
control devices, constantly receive a lot of data from them at any given time. Depending on the
equipment manufacturer used, the data that can be downloaded varies by type and format.
At the same time, each user can specify what type of data he wants to be stored by his devices for
tracking and analysis. The data generated is not large in volume, but over time this volume could
increase significantly. This data needs to be stored somewhere for a user-defined period. There are
two options for data storage - either in the cloud or in local storage, which can be in the form of an SD
card built into the controller for managing the Smart Home system.
These devices can be controlled and monitored remotely, usually via the Internet using a central
hub. However, it is known that there are very few globally accepted industry standards applicable to
smart home systems. This creates problems for homeowners who want to automate their homes.
Without industry standardization, it is possible for someone to invest in an entire system that will not
communicate adequately with all devices. Then the hacking problem arises.

Often the user has to buy an entire intelligent system from only one vendor, although there is open
source software that can be used with their own hardware. The customer could invest in a complete
system of a company, but what would happen if the manufacturer is acquired and stops the
maintenance of the systems produced so far? In 2016, Google acquired one such company, Revolve
Hub, which had its own Nest storage and monitoring system. After shutting down the servers by
Google, the whole system becomes useless, which increases the risk of hacking the smart system. [1]
2. Advantages of Smart Homes
One advantage of having a smart home is the convenience it can add to your daily routine. You
can program lighting, security, ventilation, heating and other functions to meet your daily needs. You
can also control many features in your home remotely. You can always customize what you choose to
make part of your smart home.
Figure 1: Smart home security
You can decide what is most important to you and then add products of your choice. Some people
may decide that what they need most is an automated home security system, or they want an
intelligent thermostat to be able to control the temperature when residents are not at home.
Most systems are not as difficult or expensive to install. Smart devices can often save you money
and also help you show where you can save money by tracking energy consumption and costs.
Globally, the total smart home market is expected to grow from $ 76.6 billion in 2018 to $ 151.4
billion by 2024, with a complex annual growth rate of 12 percent.
In particular, the use of smart lighting is expected to triple by 2022.
In terms of growth, it is estimated that by 2020, the availability of some level of smart housing
technology will increase to 59 percent of housing, at least according to studies by the global
consulting firm Ernst and Young (based on data from the UK) [2].
Mobility, big data and a focus on the consumer are the three market trends that are forcing
companies to embrace the cloud. The choice of solution depends on numerous and sometimes
contradictory requirements and comes down to three types of cloud environments - private, public or
hybrid cloud. The data collected by the intelligent system is stored in different ways, each of which
428
determines how, according to their capabilities, the degree of security they want to achieve. Each
storage system has its advantages and disadvantages.
3.Personal storage
Storing data in personal storage - be it a computer, flash card or server is a commonly used
solution for the home, where the data is stored for a short period of time or is not of great importance
for analysis and research. The mobile device used for the user interface of the Smart Home system
management takes data from this storage via a secured internet connection.
In order to have a longer data collection period, given their volume, greater security and analysis,
the data received from smart home devices is stored in the cloud. The cloud can be private, public or
hybrid, and again, the choice of what exactly to do is the choice of the user for security and
accessibility.
Cloud technology is a model that enables network access to shared resources such as Internet
networks, servers, storage arrays, and software applications with minimal involvement or
management by the service provider.
The use of cloud technologies has the potential to achieve great economic benefits. The cloud
model breaks the established payment methods because it applies another pricing model - pay-per-use
model. Thanks to this, consumers can accurately measure consumption and pay for as much resource
as they have spent. With this model there is no need for an annual contract and the establishment of
minimum levels of resource consumption. Usually you can activate resources whenever you want and
pay for the period during which you used the resource.
The cloud is remarkable for its flexibility, speed and convenience. Its elasticity allows for dynamic
cost configuration. Elasticity makes it possible to account for how much resource is consumed in
response to how much resource is needed.
4. Private cloud
The use of a private cloud in itself provides information about the confidentiality and criticality of
information. However, this brings with it the main features of the private cloud, namely: investing in
its own infrastructure, maintenance and security. The private cloud is used only by a certain group of
people and does not have access to the rest of the Internet space.
Private cloud (or internal) infrastructure is intended for use by a single organization or group. This
infrastructure is not shared with other organizations or users.
Private cloud has a higher price and level of security compared to public cloud. The private cloud
is protected by a firewall and can only be accessed through an internal secure network.
Private clouds are flexible and built on services. Processes, services and information are managed
within the organization itself.
In the private cloud, there are no additional security regulators, legal requirements or network
restrictions that exist in public cloud structures.
Cloud service providers and customers are building an optimized and controlled infrastructure
with increased security by eliminating network access to external users.
Private cloud services and infrastructure are maintained on-site or in a private environment, such
as an external data center. This gives the system owner exceptional access control - IT knows where
the information is located and can keep an eye on the boundaries that surround the data. Additionally,
managed private clouds allow for stable service level agreements (SLAs), which can increase
reliability.
The main disadvantage of the private cloud is its price. As the volume of collected information
increases, a constant investment in increasing the storage space is required. Requires knowledge and
IT experience, as well as constant self-monitoring. In case of incompatibility between old storage
systems and upgrading with a new generation of systems, a complete replacement of the hardware
may be required, which would make the investment extremely expensive.

5. Public cloud
The public cloud is used, where permitted, to make data publicly available and used by a large
number of users. Public cloud (or external) infrastructure is freely available through Internet access to
software applications and web services at the request of all users or a large industrial group of users.
The public cloud provides a flexible and cost-effective way to use IT solutions. The term public
does not mean that the information of the individual user is publicly available, but defines the
possibility of using the resources of cloud technology by each registered user.
Public cloud (or external) infrastructure is freely available through Internet access to software
applications and web services at the request of all users or a large industrial group of users. The main
disadvantage of public clouds is their unreliability. The public cloud often has a lower level of
protection and may be more susceptible to attacks. Some public cloud providers also reserve the right
to move data from one region to another without notifying the user, which can create legal or other
problems for companies with strict data protection rules.
6. Hybrid cloud
The hybrid cloud is a mix between the public and private cloud, carrying the characteristics of both
types of clouds. All data downloaded from a Smart Home system could be stored in both clouds,
leaving only critical and confidential data in the private one.
In addition to all these ways of storing data, the cloud could be used to back up the necessary
information. The hybrid cloud model allows the hosting of critical applications in the private cloud,
while applications with lower security and access requirements are used in the public domain. [3].
In the last few years, the popularity of the hybrid cloud has grown exponentially and today is one
of the most sought after solutions in the implementation of an enterprise IT environment. This
popularity is due to the fact that the hybrid cloud not only allows companies to scale computing
resources, but also eliminates the need for massive capital costs.
Figure 2: Hybrid cloud
Hybrid cloud is an integrated cloud service that uses both private and public cloud to perform
different functions within the same organization, allowing to increase the flexibility of the
infrastructure, going beyond the boundaries of corporate physical data centers.
Typically, a hybrid infrastructure is a combination of two or more clouds (private, public) that
remain distinguishable even though they are connected and working together. A hybrid cloud is an
infrastructure in which your servers are connected and work with your public cloud servers. Such a
scenario allows companies that do not currently use a cloud to start migrating part of their systems
there and eliminates the differences between the functionality in the internal and cloud services.

7. Conclusion
Usually, the hybrid cloud provides a balance between convenience and security. Cloud service
providers often advocate a hybrid cloud approach, focusing on using the right destination for the right
application, tailored to each individual's needs. Flexible and scalable: Because the hybrid cloud
occupies parts of both private and public cloud services, people have the ability to combine and
combine them to get the perfect balance between cost and security. Economical: Everyone can take
advantage of the cost-effectiveness of public cloud computing while enjoying the security of the
private cloud. They are gaining wide popularity: More and more people and companies are
introducing this model. After all, hybrid clouds look like a promising solution for the future.
