The terms IoT and M2M are often talked about synonymously, however, they are far from identical, and when you’re looking to implement a solution, it’s important to know the differences between the two -- or rather, when you should use one over the other.
M2M stands for "machine to machine," a technology that is similar to IoT, or the "Internet of Things," but which also has some key differences. It’s these differences that make it important to know whether your project is better suited to an M2M or an IoT solution – and, ideally, this is something you’ll define in the early stages.
