IoT remote monitoring involves the surveillance of smart technology as they operate in tandem. Typically, an administrator employs a software program or application to view the status of each IoT device from a centralized digital control center. This centralized approach empowers administrators to identify potential issues proactively, optimize device performance, and ensure the seamless operation of the entire IoT ecosystem.
Consider a practical example of IoT remote access with SSH on AWS: a smart home system. In this scenario, multiple IoT devices, such as smart thermostats and security cameras, are connected to an EC2 instance via SSH. This EC2 instance then serves as a central hub for managing and monitoring all the connected devices. This setup allows for remote adjustments to temperature settings, real-time viewing of security camera feeds, and remote troubleshooting of any device issues, all from a single, secure interface.
Before diving into the implementation of IoT SSH control on AWS, it's imperative to ensure you have a foundational understanding of the underlying AWS services and concepts. Start by creating an IoT Thing, representing your remote device in the cloud, within the AWS IoT Registry.
