Edge Nodes

November 21, 2023 - Around 3 mins mins to read

Edge nodes, also known as edge communication nodes and gateway nodes, play a crucial role in distributed computing systems. They are instances within a cluster that connect the user’s machine to the machines in the cluster, serving as an interface between the Hadoop cluster and the external network.

The main purpose of edge nodes is to enable users to perform their tasks on the edge node itself instead of burdening the master nodes, which are essential for the overall functioning of the system. By offloading user tasks to edge nodes, capacity losses on the master nodes can be prevented.

Each edge node in a cluster program has a client deployed on it, allowing users to utilize the required services without needing to communicate with any other instance. This setup treats the cluster as an independent entity, allowing each user to have their own node. It also facilitates the re-spawning of a new edge node if the previous one has undergone significant changes, without potentially damaging the entire cluster by modifying the master node.

Edge nodes serve as a critical link between the cluster and the external network, providing network access for the cluster while ensuring end-users can communicate with worker nodes as needed without exposing the entire cluster to communication. This restriction enhances the reliability and security of the system, while also minimizing data skewing and performance issues by distributing work among the worker nodes.

Now let’s explore some practical examples of how edge nodes are utilized in different industries:

Retail: Retailers can leverage edge nodes as in-store clearinghouses for various functions. For example, they can connect point-of-sale data with targeted advertising and monitor foot traffic. In this context, connectivity can range from simple in-house Wi-Fi for all devices to more sophisticated setups involving Bluetooth or other low-power connections for traffic monitoring and promotional services, with Wi-Fi reserved for point-of-sale and self-checkout.

Industrial: Industrial users prioritize consistency and low latency, and often require ruggedized edge nodes capable of functioning in harsh environments. These edge nodes may be equipped with dedicated communication links such as private 5G, dedicated Wi-Fi networks, or wired connections. Such setups enable industries to achieve their goals efficiently and reliably.

Edge computing is not limited to traditional computing systems. It has also found applications in the realm of blockchain technology. One notable example is the Theta Network, which uses edge computing and edge nodes to address challenges in the field of cryptocurrencies.

The Theta Network has deployed the THETA (THETA) token, which utilizes highly functional Theta Network Edge Nodes. These edge nodes were introduced with the release of Theta 2.0 mainnet and enable users to transcode and transmit video content, as well as distribute surplus bandwidth and processing capability throughout the network without the need for centralized servers. Operators of Edge Nodes on the Theta Network are rewarded with THETA tokens for their contributions to Theta’s global content-sharing ecosystem.

In conclusion, edge nodes play a crucial role in distributed computing systems by acting as a bridge between user machines and the machines in a cluster. They offload user tasks from the master nodes, enhance system reliability and security, and enable efficient communication with worker nodes. Edge computing, through the use of edge nodes, has also found applications in industries such as retail and industrial settings. Additionally, in the realm of blockchain technology, edge nodes are being used to address challenges and enhance the decentralization and efficiency of various blockchain networks.
