They’re like the middle managers – ensuring everything runs smoothly at the ground level. In other words, they act as intermediaries between edge devices and the broader network. They typically feature:
- More powerful processors than edge devices
- Larger storage capacities
- Advanced networking capabilities
- Security features
Edge Servers: These are more robust computing resources closer to the network’s edge than traditional cloud data centres. They can handle more complex processing tasks that edge devices might not be capable of. If edge devices are the foot soldiers, edge servers are the generals coordinating the big picture. They often include:
- High-performance CPUs
- GPUs for parallel processing
- Large amounts of RAM and storage
- Advanced cooling systems
Network Technologies: Several networking technologies enable edge computing:
- 5G: Provides high-speed, low-latency connectivity crucial for the technology
- Wi-Fi 6 (802.11ax): Offers improved performance in dense device environments
- LoRaWAN: Ideal for long-range, low-power IoT applications
