With the rise of internet of things (IoT) devices, edge computing has become increasingly important. Edge computing processes data close to the source of data generation at the edge of the network, rather than sending all the data to centralised cloud data centers for processing. This distributed model of computing allows for faster response times, greater reliability, improved security and lower latency.
Let’s take a closer look at 13 key benefits that make edge computing such a game changer for businesses across various industries.
1. Low Latency
Edge computing helps address latency issues by processing data locally before sending it to the cloud. For applications like autonomous vehicles, industrial robotics and remote medical procedures, latency needs to be as low as a few milliseconds to operate safely and effectively. Locating computation and storage closer to the endpoints helps drastically reduce lag times compared to traditional cloud models.
An autonomous vehicle travelling at highway speeds needs to respond instantly to unexpected obstacles or changes in the environment to avoid accidents. Even fractions of a second in latency could mean the difference between a smooth evasive maneuver and a collision. With the edge facilitating most onboard processing and decision-making, autonomous cars can react in near real-time without depending on laggy wireless uplinks to distant data centers.
2. Increased Reliability
With localized processing and storage at the edge, connectivity to a centralized cloud is not mandatory for basic edge functions. If the WAN connection fails, edge devices can continue autonomous operations based on local decisions. This makes edge computing highly reliable even in disaster scenarios or when backhaul networks get congested or disrupted.
3. Better User Experience
Reduced latency translates to faster response times and an improved user experience for latency-sensitive applications. Edge computing allows data processing to happen in real-time at user locations, enabling immersive experiences for AR/VR, autonomous vehicles, gaming, telemedicine and more with minimal perceptible lags. The improved user experience increases customer satisfaction and retention.
4. Distributed Load Balancing
Edge nodes are able to share some of the data processing load of centralized cloud systems. Since computation occurs near endpoints across a distributed network of edge devices, the load gets balanced significantly compared to overloading a few centralized cloud data centers. This improves overall system efficiency and scalability.
5. Privacy and Security
With edge computing, sensitive user and IoT device data need not leave organizational perimeters or local environments unless necessary. This strengthens data privacy and reduces the risk of breaches since fewer access points exist for hackers compared to centralized cloud models. Edge nodes also offer better control over data through localized storage and processing.
When data is processed and stored locally on edge nodes situated within organizational networks rather than transmitted off-premise to distant cloud facilities, it significantly reduces exposure to privacy and security threats during transmission. By minimizing external data flows, there are simply fewer potential points of vulnerability for hackers to intercept sensitive information as it moves across the open internet and multiple public network hops.
6. Lower Operational Costs
Running applications and processing data at the edge reduces cloud infrastructure and backhaul bandwidth requirements. It lowers operational expenditure on centralized cloud services, networking equipment and bandwidth fees. Edge computing is also inexpensive to deploy since existing on-premise devices can take on local edge roles. Overall operational expenditures decrease significantly.
7. Reduced Congestion
Edge nodes help filter irrelevant or unnecessary data at the source before transmitting it to the cloud. This avoids congesting costly backhaul networks with raw sensor streams and other large volumes of real-time IoT data. Filtering and preprocessing data locally reduces upstream bandwidth utilization and overall network congestion levels.
8. Mobility Support
Edge nodes provide local cloud access even when offline or on the move. This makes Edge extremely useful for applications involving location mobility through vehicles like cars, drones and robots. Edge functions continue seamlessly during transit across geographical boundaries without relying on backhaul.
For autonomous vehicles navigating busy streets, it is critical to have uninterrupted situational awareness and fast onboard decision-making regardless of network availability. With edge computing capabilities embedded directly onto vehicles, cars can seamlessly process live traffic camera feeds, sensor integrations and on-board AI systems while on the go without intermittent cloud connections hampering responsiveness. This ensures smooth autonomous operations even in network dead zones.
9. Context-Awareness
Processing data at or near endpoints allows accessing fine-grained localized context like location, time of day, environmental conditions, etc. This context-awareness enables highly optimized real-time decisions and behaviors based on proximity rather than generic cloud commands. Context helps improve outcomes in industrial automation, smart cities and other localized applications.
10. Responsiveness
Edge nodes can respond instantly to endpoint events and user requests with minimal dependencies. This makes edge deployment critically effective for time-sensitive operational technology environments involving automated vehicular control, industrial process regulation, emergency response and mission-critical systems. Edge ensures control loops remain fast and responsive at local levels.
11. Predictive Maintenance
Real-time processing of IoT sensor data streams at edge sites allows predictive detection of equipment performance anomalies and failures. Edge computing facilitates proactive maintenance by raising localized alerts for repair well before downtimes occur. This improves asset utilization through preventive maintenance across industries like manufacturing, energy, transportation and infrastructure monitoring.
12. Data Sovereignty
Sensitive operational data doesn’t need to leave regulated environments like factories, utilities, healthcare facilities, etc. Edge supports data sovereignty and compliance through regional or localized processing and storage. Organizations retain full control over confidential and regulated data within jurisdictions.
13. Legacy System Integration
Edge nodes provide an incremental modernization path for legacy systems and protocols through translation capabilities at network edges. They help bridge isolated legacy equipment and formats to newer digital ecosystems in a standards-agnostic manner. Edge ensures the smooth coexistence of old and new infrastructures during digital transformations.
Conclusion
In summary, edge computing unlocks tremendous potential through its localized capabilities. By distributing intelligent functions to network edges, edge improves latency, reliability, costs, security, user experience and system responsiveness across a wide range of consumer and industrial applications. As both 5G and IoT continue to scale, edge computing will become increasingly indispensable for realizing their full transformative impacts.
