Today, the Internet of Things (IoT) is very pervasive and is an integral part of human life. Subsequently, using various IoT platforms, a platy range of IoT devices have been deployed and developed. Although one of the most exciting IoT technology innovations gains interest, there are still concerns about its security. This paper gives the glance of different cycle of platforms and evaluate six of the most widely used IoT platforms (Azure, AWS, IBM, Google Cloud IoT, ThingSpeak, Thinger.io). Various sketches have been applied and tested in similar conditions and environments, as well as we evaluated how the platforms perform regarding the current criteria. Besides, problems and gaps in IoT platforms are discussed.
