The concept that right now we are experiencing yet-another industry revolution was developed in the beginning of this decade in Germany. It tells the story that after steam revolution, electricity revolution and computer revolution we are experiencing the revolution of production digitalization with the help of Cyber-Physical Systems (CPS), Internet of Things (IoT) and the cloud. The new revolution was named Industry 4.0. Through on of our clients we are the apt of that revolution. Our client is a manufacturer of control equipment for the wide industry. Our task is to integrate the interfaces of the physical machines with the cloud. With help of such interfaces it is possible gather the data from the physical objects and even steer the machines in the production or at the construction site. It is also possible to control and secure the machines over the interfaces we provide. In future it will be possible to optimize the planning to reduce the costs.
