Architectural Layers of Edge Computing

As you see, edge computing is utilized in lots of spheres of our everyday life. This technology is extremely helpful for lots of industries, and now you clearly understand why. So, let’s now review the actual architectural layers behind this technology.

Standard edge computing can be divided into 3 layers such as cloud layer, the edge layer, and the device layer. Let’s reach each of these layers in detail to get a broader picture.

Cloud Infrastructure Layer

Although this technology was initially created to minimize latency issues in cloud computing, cloud computing is extremely important for this technology. Generally, these 2 technologies complement one another. In some situations, information should be processed in the cloud layer. If that is the case, edge servers pass information to the cloud for deeper processing. Some critical information can be stored on the cloud.  

Intermediate Edge Computing Layer

Edge layer usually includes only edge servers, which are widely deployed in the needed locations. This layer processes information that is closer to the source and deals with the common latency issues that are correlated with the cloud. This part is considered to be the base of the entire architecture. The information from the device is processed in this layer and then, if needed, transmitted to the cloud layer. There might be some type of data that cannot be processed in the edge layer. That’s why, cloud is still important in this architecture.  

Connected Device Layer

This layer consists of the largest number of devices. The devices can be various - usual computers, mobile phones, and even as large as factories. In this layer, devices capture and collect information. For instance, hospital equipment collects patients’ vital signs. Sure, most of the information is usually processed in the cloud and edge layer, but some tasks can be analyzed at the device level as well.  

Power Supply and Edge Hardware: A Critical Connection

The power consumption depends on the number of functions used. The more functions there are, the higher the power consumption will be. As for the electricity demand, unreliable power sources can be everywhere, so in some situations, there will be a necessity for alternative power sources and energy storage systems. The wattage of the PSU fully depends on the equipment size. That’s why, for better efficiency, unit design should be simpler to minimize the response time.

How Power Supplies Impact Edge Device Efficiency

Every industry and sector has specific requirements regarding certifications and standards to guarantee a proper protection level and safety. In the usual data centers, the environment and functioning are rather stable. However, in any approach, electricity is the key factor for the proper functioning of the technology. There are lots of problems that can be provoked by the power leakage, high load, or when there is no power supply stability. The cloud environment can compensate for some of the problems, but you should also pay attention to the hardware quality. For better performance and the minimization of some security risks, high-quality PSUs are a must.
