Machine-to-Machine (M2M) means connecting many machines with a management center via wide-area mobile or satellite networks in order to monitor and control them.M2M has been used in various fields before.However, M2M is now undergoing a dramatic revolution.This is because we can more easily gather and analyze many pieces of information using recent improvements in telecommunication techniques and services and the appearance of cloud computing.Connecting real-world machines with the cloud and gathering much information will produce many new business opportunities through not only improving products and customer services, but also through selling that information.On the other hand, the requirements that M2M infrastructure needs to meet have also been changing with the appearance of the cloud.This paper will explain these new requirements and problems, introduce the solutions proposed by Fujitsu, and give some examples.
