Edge Servers

In this section you will read about :

1. How does an edge server work?

2. What is edge server architecture?

3. What are the components of edge servers?

An edge server is a hardware that executes data computation at the network's end or "edge." The edge server is capable enough to provide computation, networking, and storage like a regular server.

So, they process the data physically faster than the centralized server close to the end-users and the on-site applications. Moreover, they do not send unprocessed data to and from the data center.

How do these servers work? These interact with two separate network points, operating between the data consumers and the producers. But there is no set definition of how close these servers must be to the endpoints. So, here are the four types of edges:

• Device edge is the server which is a component within the end-user devices
• On-prem edge where the nodes are physically located within the local network or the facility
• Network edge consists of the network-specific nodes, including the telco data centers or base stations
• The regional edge where the server remains in the traditional local data center

Let’s check an example to understand how the edge server sitting between the IoT devices within a factory and enterprise data center delivers its functions:

• Different IoT devices like thermometers, cameras, sensors, etc. that are present on the factory floor interact and send the data to the local edge computing servers
• The servers can offer local processing, storage, and real-time data analysis to give appropriate visibility into production
• If the IoT sensor registers a risky increase in the machine’s temperature, the edge server can immediately identify the issue and stop the production before the machine overheats
• The edge server then sends the relevant processed data to any pre-selected corporate data center, where the authorities can devise a maintenance plan

Edge architecture refers to the distributed computing architecture that encompasses every component that actively functions within edge computing, including the clouds, sensors, devices, servers, etc. The key elements of the edge server architecture include:

• Edge devices refer to the special-purpose piece which is available with limited computing capacity
• Edge node refers to any server, device, or gateway capable of performing the edge computing
• Edge server refers to the computer located within a facility lying close to the edge device. The machines here run shared services and the application workloads, requiring greater computing power than the edge devices.
• Cloud, private or public, acts as the repository for containerized workloads like machine learning models. The cloud can also host and run the applications responsible for managing the edge nodes.
• Edge gateway refers to the edge server performing network functions like firewall management, tunneling, wireless connections, protocol translation, etc. In addition, it is the gateway that can host application workloads.

So, edge computing comprises three primary nodes: the device edge, the cloud, and the local edge. Get in touch with DC Gears to find the best brands for edge servers in the market. Then, invest in premium-quality ones to enjoy functionality at its best.

Edge computing functions with three main components in sync. These three components are:

• Internet of things (IoT) is the driving force of edge computing that enables one to store data at remote locations, far from the central data server
• Communication networks consist of edge computing and 5G communication networks that enable businesses to adopt massively decentralized computer infrastructure to use the power of comprehensive data analysis
• Cloud computing is the tool ideal for processing computer resources in the central data center, while edge computing offers quick responses, key insights, and real-time data processing
