Edge computing: A comprehensive guide

Data processing is being revolutionized by edge computing. Utilizing local computing devices such as computers, tablets, smartphones, and special-purpose edge computing devices, enables data to be processed near the source of data generation rather than in the cloud. Several advantages of this technology include increased data security, improved user experience, and reduced latency. Edge computing will be explained and discussed in this article. This article will help you understand edge computing and how it can benefit your business.

The Edge Computing concept: what is it?

Let’s start by understanding what edge computing is. Data is processed near the point of data generation in edge computing, which is a type of distributed computing. Therefore, data is processed as close to its source as possible at the “edge” of the network. This is in contrast to centralized computing, in which data is gathered and processed at a central location. Network edges can be the network’s fringes or boundaries, or the data sources that make up the network. “Edge” is a term commonly used in distributed computing to refer to data sources. Data is created at the edge, where sensors collect data, images are captured, transactions are performed, etc. Network “cores” are responsible for processing, aggregating, and distributing data.

Edge Computing’s Benefits

It is possible to reduce network congestion, enhance data security, and enhance user experience by processing data close to the source. An overview of edge computing’s benefits can be found here.

1. Enhanced data security

All data is collected and processed in a single location in the centralized computing model. In the event of a data center outage, the entire system will be unavailable. Data is processed close to the source in an edge computing model, reducing the risk of a data breach. Additionally, when the data is generated, it is encrypted. 

2. Latency is reduced 

Network delays often affect performance and user experience when data travels from a source to a central data center. A local network is used for communication in an edge computing environment. The user experience is enhanced as a result of this decrease in latency.

3. An increase in network capacity 

During centralized computing, all computation takes place at a single location. It is common for this location to experience high traffic, resulting in a slowdown in the entire system. The edge computing model performs analysis at each network node, resulting in a reduction in network congestion and an increase in network capacity.

4. Experiences that are better for users

Edge computing improves the user experience of connected data-driven environments by processing data close to the source of data generation. Due to the fact that data is processed near the user, it takes less time for it to travel to a central location and back. Edge computing devices can process data related to a shirt’s price, for example, and send it to the user immediately rather than waiting for the data to be transferred to the cloud and then delivered back to the user if a user is shopping for shirts and wants to know how much each shirt costs.

Applications of Edge Computing

A few examples of edge computing implementation can be found here.

1. The retail store

A retail store’s inventory system reads the barcode of each product when it is scanned in a retail store. Integrated computing would send store data to a centralized database, which would store and process it. Using edge computing, the data would be sent to the store’s computer and processed there.

2. A manufacturing facility

The operation of a machine in a manufacturing plant is measured by data generated by the machine. The data is transmitted into a centralized database, which is processed and stored in a centralized computing environment. In an edge computing environment, the data would be sent directly to the computer of the manufacturing company and processed on site.

3. Smart Cities

Edge computing is also being deployed in smart cities, where it can be used to monitor air quality, traffic density, and other environmental factors. All these use cases demonstrate the immense potential of edge computing and how it can be used to revolutionize the way we do things in the 21st century.

Edge computing challenges

The promise of edge computing is enormous, but it also faces several challenges. The challenges of edge computing can be summarized as follows.

1. Upfront costs are high 

Many users share computing resources in a centralized computing environment. Therefore, there is a relatively low cost per user. A dedicated computer is provided to each user in an edge computing environment. Therefore, the price per user is higher. The benefits of edge computing must outweigh the upfront costs in order to make it cost-effective. 

2. Scalability is limited 

As demand increases, you can scale the computing resources quickly in a centralized environment. The number of edge computing devices you can have in the field is limited in an edge computing environment. You may need more devices to collect and send data to the cloud if you have a large volume of data coming from sensors. In the event of a spike in demand, scaling up the system can be challenging.

3. Safeguards

Edge computing poses one of the biggest challenges in terms of data security. It is important to encrypt data as soon as it is generated, manage access, and store it securely to minimize the chances of a data breach. Additionally, edge computing can be implemented in a hybrid model, in which some data is processed at the edge while others are centralized. By using a hybrid model, the risks of edge computing can be mitigated and the technology’s benefits can be maximized.
