Introduction to Edge Computing: Everything you need to know

Edge computing is a distributed information technology (IT) project where client data is processed as close to the actual source as possible in a network environment.

Modern businesses rely on data to provide significant insight and real-time management over crucial business processes and operations. Large amounts of data may be routinely acquired from sensors and IoT devices running in real-time from remote places and harsh working environments practically anywhere globally, and today’s organizations are immersed in an ocean of data.

However, the way organizations handle computing is changing due to this virtual flow of data. The traditional computer architecture, which is based on a centralized data center and the internet as we know it, isn’t well adapted to transferring continuously flowing rivers of real-world data. Bandwidth constraints, latency concerns, and unpredictably disrupted networks can all sabotage such initiatives. Edge computing architecture is being used by businesses to address these data concerns.

In its most basic form, Edge computing moves certain storage and compute resources out from the central data center and closer to the data source. Instead of sending raw data to a central data center for processing and analysis, this work is done where the data is created, whether that’s in a retail store, a factory floor, a large utility, or throughout a smart city. Only the results of that computer effort at the edge are sent back to the primary data center for evaluation and other human interactions, such as real-time business insights, equipment maintenance predictions, or other actionable solutions.

As a result, edge computing is changing the face of IT and corporate computing. Examine edge computing, how it works, the cloud’s impact, edge use cases, tradeoffs, and implementation issues in depth.

How does edge computing work?

Data is produced in traditional enterprise computing at a client endpoint, such as a user’s computer. That data is transferred through a wide area network (WAN), such as the internet, to the corporate LAN, where it is stored and processed by an enterprise application. According to Gartner, 75% of enterprise-generated data will be created outside centralized data centers by 2025. Edge computing places storage and servers where the data is, often requiring only a partial rack of equipment to gather and analyze data. In many cases, computing equipment is housed in shielded or hardened enclosures to protect it from temperature, humidity, and other external factors. Processing usually entails normalizing and analyzing the data stream in search of business intelligence, with only the analysis’ conclusions being sent back to the main data center.

What is the significance of edge computing?

Edge computing allows computation and storage resources to be deployed closer to the data source, ideally in the same physical area. As a result, edge computing has gained traction as a viable solution to the growing network issues in transporting massive amounts of data. Edge — and fog—computing addresses three major network limits: bandwidth, latency, and congestion or reliability. The sheer volume of data generated by tens of billions of devices can overwhelm the internet, causing high congestion levels and forcing time-consuming data retransmissions. In other circumstances, network interruptions can worsen congestion and cut off communication to some internet users completely, rendering the internet of things unusable. Edge computing operates several devices over a much smaller and more efficient LAN where abundant bandwidth is used entirely by local data-generating devices, virtually eliminating delay and congestion.

What are some of the advantages of edge computing?

Edge computing addresses critical infrastructure issues such as bandwidth constraints, excessive latency, and network congestion. Examples are oil rigs, ships at sea, rural farms, and other remote settings, such as a rainforest or desert. In addition, edge computing can be used to retain data close to its source while being compliant with current data sovereignty regulations.

Edge computing in the future

According to the Gartner Hype Cycle, edge computing is approaching the Peak of Inflated Expectations and will likely reach the Plateau of Productivity in 2-to 5 years. However, edge Computing may mature sooner than expected, given continued research and improvements in AI and 5G networking technologies and the expanding demands of smart industrial IoT applications.
