• There is no “single” edge
– Depending on the application, the edge architecture will be different
– Manufacturing plant [Edge servers and gateways aggregate multiple
servers and devices in a distributed location]
– Telecommunications provider [architectures break down into a provider far
edge, a provider access edge, and a provider aggregation edge]
• Edge computing doesn’t need to be connected
– An edge device running autonomously in a hard-to-reach place like a rural
mining site can keep running when a connection drops
– When connection resumes, the system can sync and transfer data

- 5. Sponsored by: Architecture of Edge Computing • Edge computing is at the outermost edge of network • Sensor data is collected, filtered, compressed, and encrypted locally and a small quantity is sent to the cloud • Network transfer can be done in batch or offline • Increases the number of processing layers • Server location is critical • Tracking and diagnostic is critical and adds layers 5
- 6. Sponsored by: Trends • Edge gateway separates the processing and end-point – Increases the battery life of the connected devices – Add more sensors and trackers at the device • Example – Smart electricity meters generate lots of measurements at short intervals – Using data from temperature, light and other sensors, Edge Computing can respond to environment changes quickly, reducing operational cost and increasing comfort • Filtering edge data reduces cloud transfers, which increases battery life • Example – Mercedes AMG F1 team filters less valuable telemetry and transfers relevant data for offline processing 6
