Hi Learners! From this article, we will illustrate you about what is edge computing architecture with its diagram; involving with working of edge computing with ease. At the end of this article, you will get to know completely about Edge Computing Architecture without getting any hindrance.
Overview of Edge Computing
Edge computing is a distributed computing concept that brings computation and data storage closer to the location where it is needed, reducing the latency and bandwidth requirements needed to access the data. This is achieved by moving computing tasks and data storage from centralized data centers to the edge of the network, closer to the devices and sensors generating the data.
The term “edge” refers to the outer perimeter of a network, where the devices and sensors are located, and where the data is generated. Edge computing is designed to complement and enhance traditional cloud computing by allowing data processing to take place closer to the source of the data, reducing the amount of data that needs to be sent back to the cloud for processing.

3-Tier Architecture in Edge Computing:
Edge Devices Layer: The edge devices layer consists of the various devices and sensors that generate data, such as smartphones, smart appliances, wearables, and IoT devices. These devices are often equipped with sensors, cameras, and other data collection mechanisms that generate large amounts of data that need to be processed and analysed in real-time.
Edge Computing Layer: The edge computing layer is the layer between the edge devices and the cloud, and it is responsible for processing and analysing the data generated by the edge devices. This layer includes edge servers and gateways that perform computing and storage functions, as well as network routers and switches that connect the devices to the edge computing layer.
Cloud Layer: The cloud layer is the layer that provides centralized storage and processing power for data that cannot be processed at the edge. This layer includes data centers that store and process large amounts of data, as well as cloud-based applications that can be accessed from anywhere.
The architecture of edge computing is designed to address the challenges of latency, bandwidth, and reliability that are inherent in traditional cloud computing models. By bringing computation and data storage closer to the edge devices, edge computing enables real-time processing of data and reduces the need for data transmission over long distances, which can be slow and unreliable. This architecture is particularly useful for applications that require low-latency processing, such as autonomous vehicles, smart factories, and augmented reality/virtual reality (AR/VR) applications.
In addition to the three main layers, edge computing architectures can also include other components such as edge analytics, machine learning models, and security mechanisms.
- Edge analytics refers to the ability to perform data analysis and processing at the edge, without the need for data to be sent to the cloud. This allows for faster decision-making and reduces the need for expensive data transfer.
- Machine learning models can also be deployed at the edge, allowing for real-time analysis of data and the ability to make predictions or take actions based on that analysis. This is particularly useful in applications such as predictive maintenance in industrial settings or personalized healthcare monitoring.
- Security is also an important consideration in edge computing architectures. Because edge devices are often located in unsecured environments, such as public spaces or remote locations, they are more vulnerable to attacks. To mitigate this risk, edge computing architectures can include security measures such as firewalls, encryption, and access control mechanisms.

Data Processing: Edge devices perform data processing and analysis on the collected data, using algorithms and models that are deployed locally on the device. This processing can include filtering, aggregation, transformation, and analysis of the data.
Data Storage: Edge devices store the processed data locally or transmit it to a centralized cloud or data center for further storage and processing.
Communication: Edge devices communicate with other devices and cloud resources through wired or wireless networks. This communication can include data transmission, receiving updates and instructions, and performing control actions.
Security: Edge computing systems have built-in security mechanisms to protect data privacy and integrity. This includes encryption, access control, authentication, and other security measures.
Overall, edge computing enables faster processing of data, reduced latency, improved reliability, and enhanced privacy and security. It is increasingly being used in various domains, including healthcare, transportation, manufacturing, and smart cities, to enable real-time decision-making and support new applications and services.
Edge Computing Security Concerns
There are some security concerns associated with edge computing that need to be considered. Here are some of the most important security concerns related to edge computing:
Device Security: Edge computing devices such as routers, switches, and sensors are vulnerable to hacking and other attacks. These devices must be secured with the latest security patches and updates to prevent unauthorized access and protect against malware.
Data Security: Edge computing involves processing and storing data at the edge of the network, which increases the risk of data breaches. The data must be encrypted during transmission and at rest to protect against interception and unauthorized access.
Physical Security: Edge computing devices are often located in remote or unsecured locations, which increase the risk of theft, tampering, and sabotage. Physical security measures such as locking cabinets, surveillance cameras, and alarms must be implemented to prevent unauthorized access to edge devices.
Network Security: Edge computing requires a robust and secure network to prevent unauthorized access and protect against cyber-attacks. Network security measures such as firewalls, intrusion detection and prevention systems, and virtual private networks (VPNs) must be implemented to secure the network.
Compliance and Regulation: Edge computing involves processing and storing sensitive data, which must comply with relevant regulations such as GDPR, HIPAA, and PCI DSS. Compliance and regulation must be considered during the design and implementation of edge computing systems.
To address these concerns, organizations must implement a comprehensive edge computing security strategy that includes device security, data security, physical security, network security, and compliance and regulation. They must also stay up-to-date with the latest security trends and best practices to protect against emerging threats and vulnerabilities.

So, implementing edge computing involves a range of activities, from selecting the hardware and software to deploying the edge device and analysing data. The key is to ensure that the edge device is configured properly, securely connected to the network, and delivering the expected performance.
Edge Computing Vs Cloud Computing
Edge computing and cloud computing are two distinct computing models, each with its own strengths and weaknesses.
Edge computing involves processing data at or near the source of the data, rather than sending it all the way to the cloud for processing. This can be especially useful in situations where low latency is critical, such as in autonomous vehicles or industrial IoT applications. By processing data closer to the source, edge computing can reduce network latency and improve overall system performance. Edge computing is also useful in situations where there may be limited or intermittent connectivity to the cloud.
Cloud computing, on the other hand, involves using remote servers hosted on the internet to store, manage, and process data. Cloud computing is useful for a wide range of applications, including data storage, data processing, and software development. Cloud computing can also be more cost-effective than edge computing, as it allows organizations to pay only for the computing resources they need, rather than investing in expensive hardware and infrastructure.
Ultimately, the choice between edge computing and cloud computing will depend on the specific needs of the application. For applications that require low latency, edge computing may be the better choice, while for applications that require scalability and cost-effectiveness, cloud computing may be the better choice. In many cases, a combination of both edge and cloud computing may be the best approach, leveraging the strengths of each model to create a hybrid solution that meets the needs of the application.
