In this module, we learn about cloud and IoT technologies and their security issues.  Cloud Computing allows the use of hardware and software as a service over the Internet. With the cloud, users can access files and use applications from any device that can access the Internet network. An example of a Cloud Computing provider is Google's Gmail and Amazon Web services. The IoT is simply the network of interconnected devices that are embedded with sensors, software, network connectivity, and necessary electronics that enables them to collect and exchange data making them responsive. AN example of IoT devices is Nest/Ring cameras or sensors.
