Edge computing processes data near its source, reducing latency and bandwidth in IoT systems. From smart cities to autonomous vehicles, it’s transforming IoT applications. This article covers edge computing use cases, practical deployments, and challenges.
Why Edge Computing?
- Low Latency: Processes data locally for real-time responses.
- Bandwidth Savings: Reduces data sent to the cloud.
- Resilience: Operates offline during network disruptions.
Practical Example: AWS IoT Greengrass
Deploy a smart home system with AWS IoT Greengrass:
- Configure edge devices to process sensor data.
- Sync with AWS cloud for analytics.
