To ensure that an IoT device is valid and that the management platform it is communicating with is also valid, there should be an exchange of tokens to verify the client and platform. In other words, the device and the platform should both generate and exchange tokens that are unique and difficult to forge. These tokens can then be used to verify the identity of the device and the platform. DevOps is an important approach for ensuring the seamless and efficient delivery of software development, updates, and enhancements to IoT devices. By integrating IoT development into an established workflow, you’ll gain the improved collaboration, agility, assured delivery, control, and traceability that’s part of a modern DevOps process.
