Overview of Edge Computing

Edge Computing is a distributed computing paradigm in which processing and computation are performed mainly on classified device nodes known as smart devices or edge devices as opposed to processed in a centralized cloud environment or data centers. It helps to provide server resources, data analysis, and artificial intelligence to data collection sources and cyber-physical sources like smart sensors and actuators.Is edge computing seen as necessary? In the realization of physical computing, smart cities, computing, multimedia applications such as augmented reality and cloud gaming, and the Internet of Things (IoT). It is a way to streamline the movement of traffic from IoT devices and implement real-time local data analysis.

Data produced by the Internet of Things (IoT) devices to be processed where it is created instead of taking away to the routes to data centers with the help of edge computing. It also benefits Remote Office/Branch Office (ROBO) environments and organizations that have dispersed user base geographically. A significant benefit is that it improves time to action and reduces response time to milliseconds, while also conserving network resources. “Practice of processing data near the edge of your network locally or on own server produced by IoT(Internet of Things) instead of centralized data processing warehouse. ”

Internet of Things (IoT) and Edge Computing

In IoT, with the help of edge computing, intelligence moves to the edge. Like if you have massive amounts of data and for this, you have to leverage in such end to endways or highly sensor intensive or data-intensive environments where data is generated at the edge, which is due to IoT as data sensing at the edge. And also, with real-time information, the increasing unstructured data of which sensor and IoT data are part, traditional approaches don’t meet the requirements which are needed. There are various scenarios where speed and high-speed data are the main components for management, power issues, analytics, and real-time need, etc. helps to process data with edge computing in IoT.

It highly depends on the use cases. Like in telecommunication, it may be a cell phone or cell tower. Similarly, in the automotive example, it could be a car. In manufacturing, it could be a machine, and in the Information Technology field, it could be a laptop.

Edge Devices

Edge Gateway

It’s a buffer where edge computing processing is done. The gateway is the window into the environment beyond the edge of the network.

Fat Client

It’s a software that processes data in edge devices, which is opposite to thin client, which hardly transfers data.

Edge Computing Equipment

Mobile Edge Computing

It signifies the growth of edge computing systems in telecommunication systems like 5G scenarios.

What exactly is Edge Computing according to research firms

  • A network of micro data centers that store or process critical data locally and push received data to a centralized data center or repository of cloud storage.
  • Typically in IoT use cases, a massive chunk of data goes through the data center, but edge computing processes the data locally results in reduced traffic in the central repository.
  • This is done by Iot devices, transferring the data to the local device, which includes storage, compute, and network connectivity.
  • After that, data is processed at the edge while another portion is sent to storage repository or central processing in the data center.

The edge is an endpoint where data is generated through some type of interface, device, or sensor. The edge has become a major growth business. Source: The Edge- What Does It Mean For Artificial Intelligence?

Cloud Computing vs. Edge Computing vs. Fog Computing

Edge Computing and Fog Computing are the extensions of Cloud Networks, which are a collection of servers comprising a distributed network. Such networks allow organizations to exceed the resources that would be otherwise available to them. The main advantage of cloud networks is that they allowed data collection from multiple sources. Which is accessible anywhere over the internet.While Fog Computing and Edge Computing are almost similar, where the talk about intelligence and processing of data at the time of creation.

However there is a crucial difference between these two in terms of intelligence and computing power, where Fog Computing focus more on intelligence at local area network and this architecture transmits data from endpoints to a gateway where it is sent to sources for processing and return to transmission while Edge Computing focus more on computing power and processing of data locally at the edge of a network. It performs processing on embedded computing platforms interfacing to sensors and controllers.

Edge Computing is connected to dealing with persistent data near the data source, which is considered the 'edge' of the association. Click to explore about, Difference Between Cloud, Edge, and Fog Computing?

Laws Calling for Edge Computing

  • The first one is the law of physics, where you required latency sometimes, which is short, like triggering an alert and needed to react instantly, having no time to get back to the cloud, and for that, you need to able to act on data locally.
  • The second one is the law of economics, where you want to process data without much cost and traffic, so edge computing helps to process data locally at the edge of the network.
  • The last one is the law of the land, where a business might have particular requirements where certain data needs to stay local like regulation.

Security in Edge Computing

There are two sides of security in edge computing -
  1. One of them is that the security in edge computing is better than any other part of the data storage application because data is not traveling over the network.
  2. The flip side of it is that security in edge computing is less secure because the edge devices in themselves can be more vulnerable.
  3. In conclusion, data encryption, access control, and the use of virtual private networks are crucial elements to protect the edge computing system.

Use Cases where Edge Computing becomes Critical

  • Having low latency, e.g., Closed-loop interaction between machine insights.
  • For real-time analytics, access to temporal data.
  • Low connectivity, e.g., Remote Location.
  • The high cost of transferring data to the cloud.
  • Bandwidth.

  • Predictive Maintenance.
  • Energy Efficiency Management.
  • Flexible Device Replacement.

Why Edge Computing Matters?

  • When IoT devices have poor connectivity.
  • Not efficient for IoT devices to be in constant touch with the central cloud.
  • The latency factor reduces latency because data doesn’t have to traverse over a network to a central cloud for processing.
  • Where latencies are untenable like manufacturing or financial services.
  • As soon as data is produced, it doesn’t need to send over a network; instead, it compiles the data and sends daily reports to the cloud for long term storage, i.e., reduces the data traversing.
  • The buildout of the next-generation 5G cellular networks by telecommunication companies.
  • Direct access to gateway into the telecom provider’s network, which connects to a public IaaS cloud provider.

Role of Edge Computing in Healthcare

As we know, edge allows us to manage your connectivity and disperse processing closer to where data is, the advantage is a natural evolution when you optimize some part of your stack in the network with giving more localized services for your application. Moving the analysis of clinical information to edge computing is crucial for healthcare organizations that want to benefit from going digital and the key to digital healthcare Analytics. For example, in the hospital, we collect data from IoT devices, which is monitoring patients and transfer it to the trust’s electronic health record (EHR) from the bedside, with the authentication of staff to the IoT devices through proximity cards.

Role of Edge Computing in Social Good

Environmental factors like road traffic density, air quality, weather, school holidays, and other open data sets give better results by the processing of data with the help of edge computing and machine learning. The computing power will apply these factors to the data collected from healthcare at the point of admission, where data to be set where the patient expected to be discharged. There is also a movement from businesses in all sectors to use edge computing.
