IoT Development Considerations
Framework suitability for IoT use cases
Resource Constraints
Consider the processing power, memory, and storage limitations of the target IoT devices (embedded systems, edge devices)
Choose frameworks and tools that are lightweight and optimized for constrained environments to ensure efficient operation
Scalability and Performance
Assess the expected scale of the IoT application in terms of the number of devices (hundreds, thousands) and data volume (gigabytes, terabytes)
Select frameworks and tools that can handle the required scalability and provide efficient data processing and storage mechanisms
Connectivity and Protocols
Determine the communication protocols (MQTT, , HTTP) needed for the IoT application based on factors like bandwidth, power consumption, and reliability
Ensure the chosen frameworks and tools support the required protocols and provide reliable connectivity options (Wi-Fi, Bluetooth, cellular)
Security and Privacy
Evaluate the security features and mechanisms provided by the frameworks and tools to protect against cyber threats
Consider (AES, RSA), (OAuth, JWT), and secure communication channels (TLS, DTLS) to protect sensitive data and devices
Ecosystem and Community Support
