Introduction
The concept behind the Internet of Things is as powerful as it is complex, and for the elements in the IoT puzzle to mesh perfectly, they all must be part of a well-thought-out structure.
This is where IoT architecture enters the stage, especially in terms of IoT device management.
IoT architecture may vary from solution to solution, but its core consists of the four building blocks that are key in providing the fundamental features that make a sustainable IoT ecosystem: functionality, scalability, availability, maintainability and cost-effectiveness.

What is an ecosystem
General Examples of ecosystems are agroecosystem, water ecosystem, desert, forest, human ecosystem, littoral zone, marine ecosystem, prairie, rainforest, savanna, steppe, taiga, tundra, urban ecosystem, others like plants, animals, soil organisms and climatic conditions.
The IoT ecosystem is hard to define, complex, and difficult to capture due to the vastness of possibility and the rapidity with which it is expanding.

What is an IoT Ecosystem?
Speaking about any IoT ecosystem, we speak about a complex system of interconnected components and the environment where they exist and with which they interact.
The IoT ecosystem is hard to define, complex, and difficult to capture due to the vastness of possibility and the rapidity with which it is expanding.
We can use the term IoT ecosystem instead of IoT system because IoT devices have no value without the environment they exist in.

What is an IoT Ecosystem?
The Internet of Things (IoT) is a complex ecosystem of interacting elements, including sensors, gateways, servers, and platforms for accessing information.
The three facts (environment, data, people) bring the definition of an Internet of Things ecosystem, a network of interconnected devices that exists in some environment gathers the data and delivers it to people who process and analyze it using modern technologies to achieve a definite goal like building a smart home.
How does IoT technology do this? The answer is through several interconnected components that make up the IoT ecosystem.

IoT Ecosystem Definition
There is no common definition for it!
The IoT ecosystem may considered as a system consisting of networks of sensors, actuators, and smart objects whose purpose is to interconnect “all” things, including everyday and industrial objects, in such a way as to make them intelligent, programmable, and more capable of interacting with humans and each other.

Internet of Things Architecture
IoT architecture consists of the devices, network structure, and cloud technology that allows IoT devices to communicate with each other.
A basic IoT architecture consists of three layers: Perception (the sensors, gadgets, and other devices) Network (the connectivity between devices).
Such a number is chosen to steadily include these various types of components into a sophisticated and unified network.
There are essentially three major types of IoT architectural contexts: application specific, open platform and Network as a Service (NaaS).

What is Architecture?
Architecture in general is both the process and the product of planning, designing, and constructing buildings or any other structures.
By definition, a building is merely a structure with a floor, roof and walls.
True architecture goes well beyond a mere building.
Every architect seems to have a different definition of what architecture means to them.
It is important as a student to start to develop your understanding and philosophies about what architecture is for you, both as a designer and an inhabitant of architecture.

UoNA-ST560-SUM-2022, Internet of Things (IoT)
Four stages of IoT architecture
IoT system architecture is often described as a four-stage process in which data flows from sensors attached to “things” through a network and eventually on to a corporate data center or the cloud for processing, analysis and storage.
On the Internet of Things, a “thing” could be a machine, a building or even a person.
28
/59
UoNA-ST560-SUM-2022, Internet of Things (IoT)
What are the 4 stages of IoT architecture?
Step 1: sensors and actuators
The first layer is physically made up of sensors and actuators. Sensors collect data from an environment and transform it into usable data. For example, your smartphone contains sensors that detect Earth's gravitational pull, allowing you to orient your screen according to its position.
Step 2: the Internet gateway layer
The data received from the sensors is in analog form and must be aggregated and converted into digital form. This happens in the second stage of the IoT architecture, called Internet Gateway Layer. Prepare the collected data for further processing.
Step 3: Edge IT
The third stage of the IoT architecture, known as the perimeter computing system, is where better analysis and preprocessing is carried out. Edge IT systems are also located near sensors and actuators, such as a wiring closet. It can also be located in remote offices.
Step 4: Data Center and Cloud
As mentioned in step 1, all data that requires further analysis without requiring immediate feedback is sent to cloud-based data centers. These data centers are capable of analyzing, managing and storing large amounts of data. It is also much safer to store it here.

Five-layer IoT architecture
The three-layer architecture defines the main concept of the Internet of Things, but it is believed to be insufficient for research because in-depth analysis often focuses on other finer aspects of the Internet of Things (IoT).
Therefore, a five-layer architecture was proposed which additionally includes the processing and business layers.

/59
UoNA-ST560-SUM-2022, Internet of Things (IoT)
IoT architecture building blocks
While every IoT system is different, the foundation for each Internet of Things architecture as well as its general data process flow is roughly the same.
First, it consists of the Things, which are objects connected to the Internet which by means of their embedded sensors and actuators can sense the environment around them and gather information that is then passed on to IoT gateways.
The next stage consists of IoT data acquisition systems and gateways that collect the great mass of unprocessed data, convert it into digital streams, filter and pre-process it so that it is ready for analysis.
The third layer is represented by edge devices responsible for further processing and enhanced analysis of data.
This layer is also where visualization and machine learning technologies may step in.
After that, the data is transferred to data centers which can be either cloud-based or installed locally.
This is where the data is stored, managed and analyzed in depth for actionable insights.

/59
UoNA-ST560-SUM-2022, Internet of Things (IoT)
The Different Layers Of IoT Architecture
The three different layers are, namely, the perception, network, and application layers.
The perception layer is the physical layer, which incorporates sensors for sensing and gathering information about the environment. It senses some physical parameters or recognizes other smart objects in the environment.
The network layer is accountable for correlating to other smart things, network devices, and servers. Its characteristics are also used for transmitting and processing sensor data.
The application layer is effective for delivering application-specific services to the user. It defines various applications in which the IoT services can be deployed, for example, smart homes, smart cities, and smart health.

End to End Complete IoT Architecture
Before we go to end-to-end complete IoT architecture, it is needed to understand the IoT terminology!
Terminology refers to; sensors, actuators, microcontrollers, gateways, networking, platforms, protocols, App’s, data base, frameworks.
These terminologies are used for IoT applications.
An end-to-end IoT solution consists of multiple layers not just an online platform for viewing information in a grid or a chart.
These layers include device and connectivity layer, application layer, analytics layer and lastly visualization layer.

Why is IoT architecture important?
Imagine a variety of smart IoT systems from sensors and actuators to internet getaways and Data Acquisition Systems all under the centralized control of one “brain”!
The brain here can be referred to as the IoT architecture, whose effectiveness and applicability directly correlate with the quality of its building blocks.
The way a system interacts and the different functions an IoT device performs are various approaches to IoT architecture.
Since we can call the architecture the brain, it’s also possible to say that the key causes of poor integration in IoT systems are the shortage of intelligent, connection-aware architecture to support interaction in IoT systems.

Need for a robust Internet of Things architecture?
When talking about the Internet of Things, much attention is paid to its potential.
News about what IoT will be able to do and how it will empower our lives keeps flooding in, but for many it may seem that these uplifting visions don’t translate into reality as fast as we wish they could.
Nevertheless, the big change does happen, yet it happens in dribs and drabs rather than in giant leaps.
The reason for this is quite simple, but it tends to stay out of the public eye: it is the inherent diversity of IoT systems that stifles the progress and often stands in the way to make all things connected.
