Edge computing is the platform for future-proofed and next generation software. A necessary complement to the cloud, it wraps around it like a sensory cortex bringing computing, storage and information closer to the user.
Edge computing’s main goal is to minimize latency by moving the “computation” closer to the information where it's being created and reducing network connections, thereby improving the performance in terms of latency, jitter, and bandwidth. As a result, user data is not sent to the cloud but processed at the edge of the network.
In today’s hyperconnected world, data is being created in more locations than ever before, and it is ubiquitous, from smart devices to oil rigs and factories. A remarkable growth requires real-time data processing. Edge computing is a necessity for today, tomorrow and the future!
“Edge computing has the potential to transform industries ranging from agriculture to industrial manufacturing and health care with its ability to offer real-time data analysis and insight from billions of devices in the field”, says Microsoft Corp. Chief Technology Officer Kevin Scott.
Why Edge Computing for (I)IoT?
IoT deployments can benefit from edge computing in three ways:
1. Reduced Network Latency
For (I)IoT use cases where latency is an issue, relying on the cloud is not an option. The workaround is to move “the cloud” closer to them (i.e., to the Edge)! Minimizing energy use is crucial for an (I)IoT device operating on battery, for example. Let’s assume it can conduct a transaction in 20ms round trip time (RTT) to the Edge vs. 200ms RTT to the cloud. The result, it can use 10 times less battery!
2. Lower Bandwidth Requirements
Because some services will be handled at the edge, companies will no longer need bandwidth for moving large amounts of data to the core of the network and back. They will see a reduction in their overall bandwidth requirements, thus saving millions of dollars in “backhaul” and/or “cloud transfer” cost.
3. Enhanced Security
Data is more prone to attacks and breaches while in transit than when not in transit. Processing data at the edge can therefore reduce security vulnerabilities. Edge computing offers the opportunity to provide a more secure environment regardless of how one would deploy.
In summary, as the computing pendulum swings from the cloud to it’s edge, opportunities abound, particularly in the (I)IoT market. Understanding the impact of edge computing will allow you to provide seamless customer experiences, test new markets, and act on insights in real-time.
