We live in a world A connected world is something that we have wished for and it is turning into a reality with more and more devices and systems getting connected to the internet. However, as more and more systems get connected to the internet and the usage increases, do we still get the systems working at their optimum speed? IoT systems comprise of multiple layers and testing IoT is a challenge in itself. Add to it the scalability factor. IoT devices need to be high performing. always available, with minimum latency and high efficiency. In order to ascertain these you need to be able to continuously test the performance of the system and monitor it throughout. This talk focuses on the performance testing in the IoT ecosystem. Through this talk I will also share my experience with testing such systems and how I got around them. We will also look at the tools and latest trends.
