Thank you for sharing some key differences between the fog, edge and cloud computing. Edge computing places intelligence and processing power in devices such as embedded automation controllers. It would also be worthwhile to mention here that cloud computing requires 24×7 internet access, while the other two can work even without the internet. Cloud Layer: Industrial big data, business logic and analytics databases and data “warehousing” 2. As the edge computing market is growing and getting tractions, there is an important term related to edge that is catching on is fog computing. In cloud computing, data is processed on a central cloud server, which is usually located far away from the source of information. Fog computing is the concept of a network infrastructure that stretches from the outer edges of where data is created to where it will eventually be stored, whether it be in the cloud or in a customer’s data center. However, today, there is a dire need for reduced latency in specific applications, such as smart home appliances or self-driving cars. Fog refers to the network connections between edge devices and the cloud. Fog Computing vs. The growth of the IIoT has increased the need for edge, fog, and cloud platforms. Control is very important for edge computing in industrial environments because it requires a bidirectional process for handling data. Is it even necessary to send everything to the cloud? Edge computing is an extension of older technologies such as peer-to-peer networking, distributed data, self-healing network technology and remote cloud services. Fog and cloud both the computing platforms offer the company to manage their communication effectively and efficiently. Fog computing … To me, the difference between Fog Computing and Cloud Computing is where and why processing is being done. The cloud also performs high-order computations such as predictive analysis and business control, which involves the processing of large amounts of data from multiple sources. Required fields are marked *, © Copyright 2020 - WINSYSTEMS Inc. Company, Policies • Disclaimer • Press Releases • Careers. However, this distinction isn’t always clear, since organizations can be highly variable in their approach to data processing. Edge computing addresses the drawbacks of the cloud by reducing latency. They attempt to reduce the amount of data sent to the cloud. It carries storage and computational power nearer to the computer where it is really essential for the information sources. Let’s compare these three forms of data technologies, examine their differences and benefits. However, in doing so, organizations are now skeptical if cloud alone can keep up with the high influx of data? Edge We’ve heard a lot about cloud computing as the most prominent form of IoT data management. The main difference between the IoT device or application communicating with a cloud versus a node is that the bi-directional communication with a cloud server can take up to several minutes, while it may only take up to a few milliseconds when interacting with ‘nodes’ placed near the device. Your email address will not be published. Smart applications that make use of AI or ML usually deal with vast amounts of data, which becomes costly to send or store in a central cloud service. Does Tesla now have to contend with Wile E. Coyote? The main focus of doing so is to reduce the amount of data sent to the cloud. Comparisons between Edge Computing and Cloud Computing. From smart voice assistants to smart homes, brands are expanding their range of services and experimenting with different ideas to enhance the customer experience. Contrarily, in Fog computing, the data is processed within an IoT gateway or Fog nodes that are located in the LAN network.

By storing and processing data using cloud technology, we have liberated ourselves from the relentless trouble of accessing data in a limited manner. Fog and edge computing are both extensions of cloud networks, which are a collection of servers comprising a distributed network. Edge computing also improves security by encrypting data closer to the network core, while optimizing data that’s further from the core for performance. But these are overly simplified concepts which rehash ideas from the past. Thus, they are more apt for the use cases where the IoT sensors may not have seamless connectivity to the internet. The real opportunity is related to configuring nodes and optimizing performance. 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. The fundamental idea of adapting these two architectures is not to replace the Cloud completely but to segregate crucial information from the generic one. 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. “The key difference between the two architectures is exactly where that intelligence and computing power is placed,” … The fog probably has the most “fog” around its meaning. Data Communication Both Edge computing and Fog computing offer similar functionalities in terms of pushing both intelligence and data to nearby analytic platforms that are located either on, or near to the source of origination of the data, be it be cars, motors, speakers, screens, sensors or pumps. Edge Computing The world of information technology is one where grandiose sounding names often mask just how simple the underlying technologies actually are. So, for Edge computing, the data is processed on the sensor or device itself without shifting to anywhere else. For example, a jet engine test produces a large amount of data about the engine’s performance and condition very quickly. 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. It takes place on cloud services such as Amazon E2C instances. 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. Fog computing, or “fogging,” is a term used to described a decentralized computing infrastructure that extends the cloud to the edge of the network. Pertinent data is then passed to the cloud layer, which is typically in a different geographical location. They can help companies reduce their dependence on cloud-based platforms for data processing and storage, which often leads to latency issues, and are able to generate data-driven decisions faster. Industrial gateways are often used in this application to collect data from edge devices, which is then sent to the LAN for processing. This is the key distinction between fog computing vs cloud computing, where all the intelligence and computing are performed on remote servers. The main difference between edge computing and fog computing lies in where the processing takes place. Data on customer behavior is now collected through diverse and innovative ways. Your email address will not be published.

The increased distribution of data processing and storage made possible by these systems reduces network traffic, thus improving operational efficiency. Edge computing may be the better option under certain conditions, such as in the following situations: • There is not enough or reliable network bandwidth to send the data to the cloud. Such a network can allow an organization to greatly exceed the resources that would otherwise b… However, there is a key difference between the two concepts. Both Edge and Fog computing are meant to deal with one problem — optimization of performance. Fog computing – a decentralized computing infrastructure in which all data, storage, and computing applications are distributed in the most efficient way between the cloud and end devices Mobile edge computing (MEC) – an architecture that brings computational and storage capacities of the cloud closer to the edge … Organizations often achieve superior results by integrating a cloud platform with on-site fog networks or edge devices. The processors used in edge computing devices offer improved hardware security with a low power requirement. Fog computing is a term created by Cisco in 2014 describing the decentralization of computing infrastructure, or bringing the cloud to the ground. Performing computations at the edge of the network reduces network traffic, which reduces the risk of a data bottleneck. However, there is a key difference between the two concepts. Location of Data Processing The primary difference between cloud computing, Fog computing, and Edge computing is the location where data processing occurs. Note that the emergence of edge computing is not advised to be a total replacement for cloud computing. The internet has transformed from a mere source of information to the data feeding mechanism aiding high-end computational power. Fog computing uses a centralized system that interacts with industrial gateways and embedded computer systems on a local area network, whereas edge computing performs much of the processing on embedded computing platforms directly interfacing to sensors and controllers. - Fog Computing applies its principles horizontally across different types of domains, i.e., IoT verticals like industrial automation, smart cities, oil and gas, transportation of men, Today, the technology has evolved multifold, so much so you can live stream your videos in 4K to the world. However, the need for collecting huge amounts of data, especially in the age of 5G network and consumers watching 4K or at least HD quality data online, companies might have to push their boundaries to adopt Fog or Edge computing. The benefits of edge computing include reduced bandwidth use, which saves money and avoids bottlenecks, increased security via encryption at source, and optimizing data performance by dividing workloads between the edge and the cloud. Fog Computing: Fog computing is a decentralized computing infrastructure or process in which computing resources are located between the data source and the cloud or any other data center. Cloud computing architecture has different components such as storage, databases, servers, networks, etc. Most enterprises are familiar with cloud computing since it’s now a de facto standard in many industries. Filed Under: Knowledge Hub, Tech Library, WINSights Blog. The IIoT is composed of edge, fog and cloud architectural layers, such that the edge and fog layers complement each other. 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. Most enterprises are familiar with cloud computing since it’s now a de facto standard in many industries. Living on the Edge — All You Need to Know About Edge Computing, Understanding Software Architecture Frameworks — Microservices, Monoliths, SOA, and APIs. - Fog Computing extends cloud into Fog domain at the edge and performs cloud functions in a single continuum.
