edge computing explained

Tips and tricks for 5G and the network edge, Digital transformation: New data shows speed gains – and culture worries, Working from home after COVID-19: 6 ways to make your case, 5 ways cloud storage and data services enable the future of development in the AI age. Rosa Guntrip, senior principal marketing manager, cloud platforms at Red Hat: "Edge computing refers to the concept of bringing computing services closer to service consumers or data sources. An edge data center can help solve the problem of latency by being nearer geographically to the source of data that you need—basically running fewer processes from a cloud (where latency and security can be an issue) to more localized places. It does by using small power cell stations to enable data to travel at high speeds—without having to travel long distances to a cloud or data center. These are the urban cores, hospitals, factories, transportation hubs, and a wide range of spaces where we all work, play, and live as well as where we all want to use ‘smart’ things to deliver optimal digital experience.”, Jason Mann, Vice President of IoT at SAS: “Edge computing refers to the engagement and analysis of data at its point of origin with available computing and storage capabilities.”, Nima Negahban, CTO at Kinetica: “Technically, edge computing is a distributed paradigm that enables data to be processed locally across smart objects, mobile phones, and local networks. It needs a cloud to configure, deploy and manage IoT devices for analyzing large datasets from different data sources. Edge computing involves shifting processing power from the cloud to devices like smart refrigerators and automated manufacturing systems. Online Storage or Online Backup: What's The Difference? As many edge computing devices and edge data centers are connected to the network, there are least chances for one failure to shut down entire services. Edge computing networks can still connect to the cloud when necessary, but they don’t *need* the cloud to function. Edge computing operates in the conditions with the limited connectivity so business operations can be carried out without worrying about the data loss. Fueled by emerging use cases like IoT, AR/VR, robotics, machine learning, and telco network functions that require service provisioning closer to users, edge computing helps solve the key challenges of bandwidth, latency, resiliency, and data sovereignty. As edge technologies mature, the cloud will grow alongside them, establishing a continuum between the two domains. In between, there may be edge servers, edge gateways or micro data centers that help facilitate local processing and reduce round trip data times to the cloud. But have enough IT leaders prioritized dealing with the related culture change? In a nutshell, edge computing is an alternative to cloud computing where your data processing power is at the “edge” of your network. The power, cooling, space and such other functional costs make these clusters expensive. Moving the computer workload closer to the consumer reduces latency, bandwidth and overhead for the centralized data center, which is why it is a growing trend in big data. No wonder that edge computing is in virtually all IoT trend reports. Instead, it stays at its point of creation. Edge computing is an important emerging paradigm that can expand your operating model by virtualizing your cloud beyond a data center or cloud computing center. Let’s explain a few of the ground principles of edge computing to understand how this principle will apply across the technologies we know and use every day. Edge Computing and Natural Disasters One thing that doesn’t get mentioned enough when people talk about edge computing is the benefits it adds during natural disasters. So what exactly is edge computing? It could be a cell tower, a smartphone, an IoT device or a self-driving car. ], "For edge devices to be smart, they need to process the data they collect, share timely insights and if applicable, take appropriate action. With the advent of edge computing, decisions can be made at the collection point or at a location physically close to the collection point. In general, we can define three kinds of IoT Edge Computing: Local devices for accommodating a specific and well-defined purpose. Sure, if a data center gets knocked off during a disaster, then edge computers can pick up the load, but some say edge networks must be programmed to keep the internet alive during these times. Relying on edge computing allows the drones to transmit the data in real time and receive instructions in a timely fashion. Bringing computation to the network’s edge minimizes the amount of long-distance communication that has to happen between a client and server, thereby reducing latency and bandwidth use. Along that edge are edge devices. There’s also the IoT, which includes devices such as Nest thermostats or security cameras, electric appliances, voice assistants, such as Google Home or Alexa, and sensors. Edge computing enables data to be analysed, processed and transferred at the edge of a network. To learn more about all things cloud, follow our state of the cloud. Encryption and VPN tunneling will be increasingly important as edge computing grows. By enabling edge computing, crucial data can be transmitted from the ambulance to the hospital in real time, saving time and arming emergency department teams with the knowledge they need to save lives. The rise of edge computing is an iteration of a well-known technology cycle that begins with centralized processing and then evolves into more distributed architectures. That eases us into the edge conversation. That’s the only way we can improve. Like The Enterprisers Project on Facebook. So how do you know when you need to build those neighborhood pizza joints, er, use edge computing? That makes edge computing more efficient and scalable and reduces network load. Data processing happens at the source, far away from the cloud – or at the “edge”. The difference is in technologies such as machine learning, AI and a cloud backend. At the pitcher’s mound is the centralized cloud and, farther out, in the outfield, is where the “edge” resides. L' edge computing (informatique en périphérie ou informatique en périphérie de réseau) est une méthode d'optimisation employée dans le cloud computing qui consiste à traiter les données à la périphérie du réseau, près de la source des données. That said, we may see a decoupling of functions from the cloud. This can aid in avoiding server downtime, ensuring reliable operations in remote locations and avoiding unplanned downtime. Depending on the bottleneck of the system it was designed as a centralized or decentralized system. With VDI infrastructure, you need extremely low latency because you are sending your keystrokes and mouse movements to basically a remote desktop,” Satyanarayanan explained. Edge computing puts storage and servers where the data is, often requiring little more than a partial rack of gear to operate on the remote LAN to collect and process the data locally.In many cases, the computing gear is deployed in shielded or hardened enclosures to protect the gear from extremes of temperature, moisture and other environmental conditions. Edge computing is even the answer to most IoT security concerns. Twenty-one percent of IT leaders accelerated their digital transformation work during COVID-19, Red Hat's Global Tech Outlook 2021 research says. So, what exactly is edge computing, and how does it work? Digitalizing a factory. Cloud computing has revolutionised how people store and use their data. In healthcare, an edge computer could be an all-in-one solution or a box PC. Early on, it was perhaps most associated with the Internet of Things (IoT). Edge Computing: Explained (theverge.com) 159 Posted by BeauHD on Monday May 07, 2018 @10:30PM from the fancy-lingo dept. The origins of edge computing lie in content delivery networks that were created in the late 1990s to serve web and video content from edge servers that were deployed close to users. Edge computing and IoT – when intelligence moves to the edge Edge computing and the Internet of Thing are a perfect match for several reasons. Stephanie Overby is an award-winning reporter and editor with more than twenty years of professional journalism experience. Edge computing is a distributed computing paradigm bringing compute, storage, and applications closer to where users, facilities, and connected things generate, consume, and/or leverage data. This puts data, compute, storage, and applications nearer to the user or IoT device where the data needs processing, thus creating a fog outside the centralized cloud and reducing the data transfer times necessary to process data. In fact, edge is a key enabler for unlocking the full power of data in the cloud. A decentralized, distributed computing paradigm is also fundamental to torrenting and blockchain. A good analogy would be a popular pizza restaurant that opens smaller branches in more neighborhoods, since a pie baked at the main location would get cold on its way to a distant customer.”. Over the past decades we’ve seen different architectural patterns for systems. Like the edge, fog computing moves the workload closer to the network edge, reducing data travel, latency and bandwidth. It may be referred to as a distributed IT network architecture that enables mobile computing for data produced locally. Other examples include smart utility grid analysis, safety monitoring of oil rigs, streaming video optimization, and drone-enabled crop management. Edge computing is transforming the way data is being handled, processed, and delivered from millions of devices around the world. As such, rather than sending raw data back to a cloud or data center, the device generates action independently or sends only already refined data to the network, in effect storing, processing, analysing and reacting. “Edge computing” is a type of distributed architecture in which data processing occurs close to the source of data, i.e., at the “edge” of the system. Don’t worry, it’s actually pretty easy to understand. After months of grappling with the COVID-19 pandemic, what if your company wants you to return to the office – and you want to continue with remote work? Try this one out: Michael Clegg, Vice President and General Manager of IoT and Embedded at Supermicro: “By processing incoming data at the edge, less information needs to be sent to the cloud and back. The Edge Explained. Edge computing is the practice of capturing, storing, processing and analyzing data near the client, where the data is generated, instead of in a centralized data-processing warehouse. What is edge computing? Sometimes, nothing works like a food analogy. What Is Edge Computing? Rather than relying on the security of a hackable cloud, devices will use edge computing to encrypt and secure data at the source, meaning it passes through as few devices as possible. Yet, explaining edge computing to non-technical audiences can be tough – in part, because this type of data processing can take place in any number of ways and in such a variety of settings. Part of the issue is that the term “edge computing” is forced to cover a lot of territory. What is edge computing? Hence, the data is stored at intermediate points at the ‘edge’ of the network, rather than always at the central server or data center.”, Richard Villars, Vice President, Data Center and Cloud at IDC: “IT at the edge is about the consumption of IT resources in increasingly ‘smart’ edge locations. The move toward edge computing is driven by mobile computing, the decreasing cost of computer components and the sheer number of networked devices in the internet of things (IoT). How to Access the Deep Web and the Dark Net, How to Securely Store Passwords in the Cloud, MP4 Repair: How to Fix Corrupted Video Files in 2019, edge computing will replace cloud computing. Explained. Edge-computing gateway device/Industrial PC for the IIoT and Industry 4.0. The implications of edge computing are far-reaching, trickling down from software development and … Many consider such devices little more than expensive wire taps. [ Want to learn more about implementing edge computing? Despite an ever-increasing number of computing devices and key early-stage gains by companies like those in the Kinetic Edge Alliance, Satya said edge computing is still in a holding pattern. Another example is CDNs, such as Cloudflare and Akamai. Let's look at some examples: Stay on top of the latest thoughts, strategies and insights from enterprising peers. ], Ryan Martin, principal analyst at ABI Research: “Edge computing is the idea that processing should happen closer to where data is created, when it makes sense. This approach reduces the need to bounce data back and forth between the cloud and device while maintaining consistent performance. Edge & Fog Computing Explained. Edge computing allows those devices to learn behavior and react. Edge data centers give enterprises the power to support their end users with limited physical distance and latency. Subscribe to get the latest thoughts, strategies, and insights from enterprising peers. That said, there is concern about edge devices themselves being vulnerable. Time Machine vs Arq vs Duplicati vs Cloudberry Backup. An example use case is Internet of Things (IoT), whereby billions of devices deployed each year can produce lots of data. We’re going to explain edge computing as it relates to cloud computing, as well as the similar fog computing, and give a few examples. As usual, drop us a comment or tweet, and thanks for reading. Edge computing is the computational processing of sensor data away from the centralized nodes and close to the logical edge of the network, toward individual sources of data. Edge computing is transforming the way data is being handled, processed, and delivered from millions of devices around the world. Edge computing explained. One of the most reliable and widely used ways to manage assets is via an MICA RF-R500 RFID system. Edge computing is still considered a new paradigm, despite its history. It’s impractical and cost prohibitive. Even though edge computing hardware is defined by its location, and not its size, small but powerful platforms make for more convenient installations in a wider range of applications with lower power consumption. IoT, IIoT, Industry 4.0., I4.0: These terms are thrown around, often interchangeably, but they each have very definitive terms and uses.Knowing this is the first step to navigating the connected world. What’s more, industry giants, such as Intel, estimate that self-driving cars will produce 40TB of data a day by 2020. Your Nest thermostat adjusting the temperature when you come home from work is one example of that. Edge computing is already used in ample applications, mainly in combination with the Internet of Things (IoT). Edge computing becomes more and more common for each day both in the consumer market and in the manufacturing industry. In edge computing, data is processed by the device itself or by a local computer or server, rather than being transmitted to a … Less data in the cloud means there is less data to be in a breach or leak. Explained: From the cloud, computing moves to the edge By 2025, says the global research and advisory firm Gartner, companies will generate and process more than 75% of their data outside of traditional centralised data centres — that is, at the “edge” of the cloud. The Enterprisers Project aspires to publish all content under a Creative Commons license but may not be able to do so in all cases. Edge computing is more of a complement to cloud computing; it can’t replace the cloud computing because there will always be the need for central processing. Like the metaphorical cloud and the Internet of Things, the edge is a buzzword meaning everything and nothing. "If I post one of my videos online, and it starts to get hits, I have to cache it on more servers, way back in the cloud. It attracted particular attention in 2006.The year when Amazon first promoted its “Elastic Compute Cloud.” This opened up a raft of new opportunities in terms of computation, visualization, and storage capacity. Edge intelligence refers to the ability to intelligently distribute computing between edge and cloud resource.”, Todd Loeppke, Lead CTO Architect at Sungard Availability Services: “Prior to edge computing, data was collected from distributed locations outside the traditional data center. In this video, I explain what edge computing (the edge) is and why it will be important in the future when IoT becomes more mainstream. While edge computing could theoretically eclipse cloud computing, the cloud isn’t going anywhere. In simple words, Edge is the point from where the data will be delivered or processed.Edge computing in IoT will elevate traditional IoT.
