Most people have a good handle on “The Cloud” and what it can do, but newer terms like edge computing or fog computing aren’t as well understood, even though they are helping drive innovation in many areas. So we wanted to help define these three terms and show how they are being used to power IIoT architectures. Adopting edge computing is a high priority for many telecommunications service providers, as they move workloads and services toward the network’s edge.

After this gained a little popularity, IBM, in 2015, coined a similar term called “Edge Computing”. The use of automated guided vehicles on industrial shop floors provide an excellent scenario that explains how fog computing functions. In this scenario, a real-time geolocation application using MQTT will provide the edge compute needed to track the AGVs movement across the shop floor. Intel estimates that the average automated vehicle produces approximately 40TB of data every 8 hours it is used. In this case, fog computing infrastructure is generally provisioned to use only the data relevant for specific processes or tasks. Other large data sets that are not timely for the specified task are pushed to the cloud.

How Do Companies Use Edge Computing With Datacenters And Public Cloud?

An infrastructure and application development platform that is flexible, adaptable, and elastic is required to fulfill these different needs and provide the connection between these various stages. By treating each incoming data point as an event, organizations can apply decision management and AI/ML inference techniques to filter, process, qualify, and combine events to deduce higher-order information. One way to view edge computing is as a series of circles radiating out from the code data center.

  • But in fog computing, data is transmitted from the point of collection to a gateway for processing, then sent back to the edge for action.
  • Edge computing can reduce network costs, avoid bandwidth constraints, reduce transmission delays, limit service failures, and provide better control over the movement of sensitive data.
  • Your Red Hat account gives you access to your member profile, preferences, and other services depending on your customer status.
  • It generates a huge amount of data and it is inefficient to store all data into the cloud for analysis.
  • So that spaces can be utilise as much as possible for better responses and fast processes.

Then it’s back to the edge for the runtime inference stage, when those machine learning models are served and monitored. A fog computing framework can have a variety of components and functions depending on its application. It could include computing gateways that accept data from data sources or diverse collection endpoints such as routers and switches connecting assets within a network. With the ever-evolving technology landscape, it can be hard to keep up with new terminology and capabilities.

Distributing the data at the edge so that the result will be sent to the cloud not the raw data itself. A portfolio of enterprise software optimized for lightweight deployment at the edge. A related concept, Industrial Internet of Things , describes industrial equipment that’s connected to the internet, such as machinery that’s part of a manufacturing plant, agriculture facility, or supply chain.

Fog Computing Vs Edge Computing

For enterprises and service providers, edge means low-latency, highly available apps with real-time monitoring. Edge computing is computing that takes place at or near the physical location of either the user or the source of the data. By placing computing services closer to these locations, users benefit from faster, more reliable services while companies benefit from the flexibility of hybrid cloud computing. Edge computing is one way that a company can use and distribute a common pool of resources across a large number of locations. Many use the terms fog computing and edge computing interchangeably, as both involve bringing intelligence and processing closer to where the data is created.

Preventive And Predictive Maintenance And Edge Computing

Red Hat offers a powerful portfolio of technologies that extends and complements its open hybrid cloud platforms to manage and scale your hybrid cloud environments. There is no difference between fog computing and edge computing other than terminology. Radio access networks are connection points between end-user devices and the rest of an operator’s network.

Fog Computing definition

To achieve real-time automation, data capture and analysis has to be done in real-time without having to deal with the high latency and low bandwidth issues that occur during the processing of network data. Although the cloud provided a scalable and flexible ecosystem for data analytics, communication and security challenges between local assets and the cloud lead to downtime and other risk factors. Fog computing may seem very similar to edge computing because both involve moving processing closer to where data is collected.

Make it easier to place your compute power closer to the data source with this consistent, centralized management solution for your core datacenters and extending to the edge. Automating edge workloads can simplify IT tasks, lower operational expenses, and deliver smoother customer experiences across highly distributed edge architectures. Red Hat® Ansible® Automation Platform scales automation to the edge and provides the flexibility to meet the often limited physical space and power requirements of edge deployments. It offers a single, consistent view—from edge locations to core datacenters and cloud environments—that allows operations teams to reliably manage hundreds to thousands of sites, network devices, and clusters.

Edge Delivery

As the growth of sensor network is increased, the demand to control and process the data on IOT devices is also increasing. Proponents of edge computing tout its reduction of points of failure, as each device independently operates and determines which data to store locally and which data to send to the cloud for further analysis. Proponents of fog computing over edge computing say it is more scalable and gives a better big-picture view of the network as multiple data points feed data into it. Fog computing was coined by Cisco and it enables uniformity when applying edge computing across diverse industrial niches or activities. This makes them comparable to two sides of a coin, as they function together to reduce processing latency by bringing compute closer to data sources.

To mitigate these risks, fog computing and edge computing were developed. Edge Computing is a distributed computing model that collects data at the edge of the network, like on a plant floor, and processes that data in real time. Edge computing addresses the drawbacks of the cloud by reducing latency. To break it down to the simplest terms, cloud computing means that data is processed and accessed via the Internet, rather than on a hard drive or local server. For businesses, cloud computing reduces cost through metered services and the ability to scale as needed to meet demand. It also allows employees to access documents from wherever they happen to be, as long as they have network access via the Internet.

Fog Computing definition

An edge platform can help deliver consistency of operations and app development. It should support interoperability to account for a greater mix of hardware and software environments, as opposed to a datacenter. An effective edge strategy also allows products from multiple vendors to work together in an open ecosystem.

Fog computing is bringing data processing, networking, storage and analytics closer to devices and applications that are working at the network’s edge. That’s why Fog Computing today’s trending technology mostly for IoT Devices. Thus, the option of processing data close to the edge decreases latency and brings up diverse use cases where fog computing can be used to manage resources. Here, a real-time energy consumption application deployed across multiple devices can track the individual energy consumption rate of each device. For every new technological concept, standards are created and they exist to provide users with regulations or directions when making use of these concepts.

In the case of the edge and fog computing, while edge computing refers to bringing compute closer to data sources, fog computing is a standard that defines its operation and application in diverse scenarios. Milliseconds count when serving high-demand network applications, like voice Cloud Computing and video calls. Data is transmitted from endpoints to a gateway where it is then transmitted to sources for processing and return transmission. In edge computing, intelligence and power of the edge gateway or appliance are in devices such as programmable automation controllers.

Address the needs of different edge tiers that have different requirements, including the size of the hardware footprint, challenging environments, and cost. Data management becomes tedious as along with the data stored and computed, the transmission of data involves encryption-decryption too which in turn release data. It improves the overall security of the system as the data resides close to the host.

How Edge Relates To Cloud Computing

This selected data is chosen for long-term storage and is less frequently accessed by the host. The devices comprising the fog infrastructure are known as fog nodes. We bring 10+ years of global software delivery experience to every partnership.

Red Hat’s broad portfolio provides the connectivity, integration, and infrastructure as the basis for the platform, application, and developer services. These powerful building blocks enable customers to solve their most challenging use cases. Physical security of edge sites is often much lower than that of core sites. An edge strategy has to account for a greater risk of malicious or accidental situations.

Edge computing can reduce network costs, avoid bandwidth constraints, reduce transmission delays, limit service failures, and provide better control over the movement of sensitive data. Load times are cut and online services deployed closer to users enable both dynamic and static caching capabilities. A step further is autonomous vehicles—another example of edge computing that involves processing a large amount of real-time data in a situation where connectivity may be inconsistent.


Once a device is consuming excessive energy, the notification triggers the app to offload some of the overloaded device’s tasks to other devices consuming less energy. The controller executes the system program needed to automate the IoT devices.

What Is Iot, And What Are Edge Devices?

Another example of edge computing is happening in a nearby 5G cell tower. Telecom providers increasingly run their networks with network functions virtualization , using virtual machines running on standard hardware at the network edge. An edge computing strategy enables the providers to keep the software at tens of thousands of remote locations all running consistently and with uniform security standards. Applications running close to the end user in a mobile network also reduce latency and allow providers to offer new services. In highly distributed environments, communication between services running on edge sites and cloud needs special consideration. The messaging and data streaming capabilities of Red Hat AMQ support different communication patterns needed for edge computing use cases.

Can be managed using the same tools and processes as their centralized infrastructure. This includes automated provisioning, management, and orchestration of hundreds, and sometimes tens of thousands, of sites that have minimal IT staff. Edge computing can simplify a distributed IT environment, but edge infrastructure isn’t always simple to implement and manage. Network functions virtualization is a strategy that applies IT virtualization to the use case of network functions. NFV allows standard servers to be used for functions that once required expensive proprietary hardware.

Also it makes cloud computing concepts clear which helps to maintain the relevant and crucial data in the network. As the Fog Computing filters the data at the edge of the smart devices before sending to the Cloud. So that spaces can be utilise as much as possible for better responses and fast processes. In the Field of Internet of Things the devices by themselves can recognise the environment and conduct a certain functions by itself. Cloud Computing which is based in sensor networks manages huge amount of data which includes transferring and processing which takes delayed in service response time.

It’s a container-centric, high-performance, enterprise-grade Kubernetes environment. Data-intensive applications can be broken down into a series of stages, each performed at different parts of the IT landscape. Edge comes into play at the data ingestion stage—when data is gathered, pre-processed and transported. The data then goes through engineering and analytics stages—typically in a public or private cloud environment―to be stored and transformed, and then used for machine learning model training.

For an example of edge computing driven by the need for real-time data processing, think of a modern manufacturing plant. On the factory floor, Internet of Things sensors generate a steady stream of data that can be used to prevent breakdowns and improve operations. By one estimate, a modern plant with 2,000 pieces of equipment can generate 2,200 terabytes of data a month. It’s faster—and less costly—to process that trove of data close to the equipment, rather than transmit it to a remote datacenter first. But it’s still desirable for the equipment to be linked through a centralized data platform. That way, for example, equipment can receive standardized software updates and share filtered data that can help improve operations in other factory locations.
