Amazon FreeRTOS **Rating:** 3.5/5.0 stars **Reviewed by:** Maricela D. | Accounting Techn, Government Administration, Small-Business (50 or fewer emp.) **Reviewed Date:** April 16, 2019 **What do you like best about Amazon FreeRTOS?** This software is easy for applications to connect to AWS IoT & AWS Greengrass, directly, and without having smart gateways acting as intermediaries. At start up you get components for basic MQTT communication, AWS endpoint discovery, over the air firmware updates, and others. As a great plus lightweight devices, sensors and actuators, can be implemented using this system as they will use MQTT to communicate with the Greengrass core, eliminating the need to integrate other communications protocols to the system. This is just the beginning of the system project. We will update further on as the project progresses. **What do you dislike about Amazon FreeRTOS?** There are security issues with the system that has added risk that could lead to information leaking, a denial of service attack and other threats. And another is that the CPU loads at 100 percent for some seconds. Don't know why this is necessary, and not sure as to what is going on to have that happen. But the security threats are the most important of my dislikes. Would like to see what they do with that regard. **Recommendations to others considering Amazon FreeRTOS:** There are other options such as CoreOS but just try it out. **What problems is Amazon FreeRTOS solving and how is that benefiting you?** So far, we are in the beginning stages of the trying the system against CoreOS. ### 5.
