Embedded Systems & Edge Computing
Understand WASM's role in resource-constrained environments, enabling secure and efficient execution on IoT devices and edge nodes.
Welcome to the Edge
Imagine tiny computers doing big tasks! This is the world of embedded systems and edge computing.
Embedded systems are specialized computer systems designed for specific functions within a larger mechanical or electrical system, like in smart appliances or industrial sensors.
Edge computing brings computation and data storage closer to the data source, reducing latency and bandwidth use. Think smart cameras analyzing video on-device, not in the cloud.
Challenges at the Edge
Edge and embedded environments come with unique challenges:
- Resource Constraints: Limited CPU, memory, and storage.
- Power Efficiency: Often battery-powered, requiring minimal energy use.
- Intermittent Connectivity: Devices might not always have a stable internet connection.
- Security: Devices can be physically exposed, making them targets for tampering.
Traditional software can struggle in these demanding conditions.
