However, today, there is a dire need for reduced latency in specific applications, such as smart home appliances or self-driving cars. As mentioned, the terms “cloud,” “edge,” and “fog” represent three layers of computing: 1. This trend has made it more challenging to consolidate data and processing in a single data center, giving rise to the use of “edge computing.” This architecture performs computations near the edge of the network, which is closer to the data source. It establishes a missing link between cloud computing … Below are the most important Differences Between Cloud Computing and Fog Computing: 1. Mung Chiang, one of United States’ lead researchers on fog and edge computing ga… “The key difference between the two architectures is exactly where that intelligence and computing power is placed,” … However, there is a key difference between the two concepts. Computers which connects with all the devices in the cloud are called fog computing or edge computing. Fog Computing vs. If a part of data processing can be done at the Edge of the network, only crucial information can be passed to the cloud server that would help in reducing costs by a significant margin. We’ve asked industry experts for insight. While Edge computing is widely preferred by middle-ware companies and telecoms that work with backbone network and radio networks, Fog computing is more desired by data processing companies and service providers. Internet of Things (IoT) has transformed the way businesses work, and the industry has seen a massive shift from on-premise software to cloud computing. Fog and edge computing systems both shift processing of data towards the source of data generation. The internet has transformed from a mere source of information to the data feeding mechanism aiding high-end computational power. As a distributed environment, the concept "Edge computing" applies to computing. Edge computing addresses the drawbacks of the cloud by reducing latency. So, for Edge computing, the data is processed on the sensor or device itself without shifting to anywhere else. Most enterprises are now migrating towards a fog or edge infrastructure to increase the utilization of their end-user and IIoT devices. Cloud, fog, and edge computing may look very similar terms, but they have some differences, functioning as different layers on the IIoT horizon that complement each other. The terms edge and fog computing seem to be more or less interchangeable, and they do share several key similarities. The main difference between edge computing and cloud computing is that edge computing offers a flexible, decentralized architecture, which means that everything is processed on the devices itself. On the other hand, Fog computing shifts the Edge computing tasks to processors that are connected to the LAN hardware or the LAN directly so that they may be physically more distant from the actuators and the sensors. It carries storage and computational power nearer to the computer where it is really essential for the information sources. In Fog, the data remains distributed among nodes. These computations are then passed back down the computation stack so that it can be used by human operators and to facilitate machine-to-machine (M2M) communications and machine learning. However, the key difference between the two lies in where the location of intelligence and compute power is placed. Shifting computing power closer to the Edge of the network will help in reducing cost as well as improving security. The processors used in edge computing devices offer improved hardware security with a low power requirement. Both the technologies leverage the power of computing capabilities within a local network to perform computation tasks that may have been carried out in the cloud easily. Thus, it is difficult to manipulate data as compared to the centralized structure of Cloud computing. Cloud computing is best suited for long term in-depth analysis of data, while fog and edge computing are more suitable for the quick analysis required for real-time response. Data on customer behavior is now collected through diverse and innovative ways. This is the key distinction between fog computing vs cloud computing, where all the intelligence and computing are performed on remote servers. Comparisons between Edge Computing and Cloud Computing. Today, the technology has evolved multifold, so much so you can live stream your videos in 4K to the world. The growth of the IIoT has increased the need for edge, fog, and cloud platforms. The fundamental idea of adapting these two architectures is not to replace the Cloud completely but to segregate crucial information from the generic one. Within the broad topic of edge computing, MEC is the widely accepted standardthat must be met for a technology to be considered edge computing. However, this distinction isn’t always clear, since organizations can be highly variable in their approach to data processing. These architectures allow organizations to take advantage of a variety of computing and data storage resources, including the Industrial Internet of Things (IIoT). Fog Computing. The term Edge computing and Fog computing seem interchangeable, and for a fact, they do share some key similarities.

Fog computing was first created by Cisco with a goal to extend cloud computing to the edge of a company’s network. Fog Layer: Local network assets, micro-data centres 3. Again, since the data is distributed among nodes in Fog computing, the downtime is minimal as compared to cloud computing, where everything is stored in one place and if anything goes wrong with it, it takes down the whole system. They are the same. Edge computing is used to process time-sensitive data, while cloud computing is used to process time-dependent data. Along with cloud computing, fog and edge computing are becoming popular as well. Organizations often achieve superior results by integrating a cloud platform with on-site fog networks or edge devices. The fog probably has the most “fog” around its meaning. It is going from centralized to distributed architectures, with videos streaming, augmented & virtual reality, and going beyond that which has enabled many advanced features for the end-users. The main focus of doing so is to reduce the amount of data sent to the cloud. The main difference between edge computing and fog computing lies in where the processing takes place. But these are overly simplified concepts which rehash ideas from the past. Edge Computing Edge computing processes data away from centralized storage, keeping information on the local parts of the network — edge devices. The considerable processing power of edge nodes allows them to perform the computation of a great amount of … Smart applications and IoT based devices require instant decision-making tools, and while companies are adding new, enhanced, much better features that help in quick decisions, there’s still a latency or lack of decisive nature, which calls for the implementation of Fog and Edge computing.
