Providing a New Model for Partially Cloud Computing- based SCADA Systems. Case: Tehran's SCADA system

Cloud computing provides the ability to share a set of configurable computer resources, including networks, servers, storage applications, and services in a simple way through the network. By entering into a cloud environment, SCADA providers can reduce costs significantly and yet increase SCADA’s functionality, reliability, and performance. Nowadays, SCADA systems play an important role in the control of key facilities of every metropolis. Regarding the implementation of these systems in various sectors such as water, electricity, gas, etc., their malfunction will face their users with serious and irreversible risks. Thus, the proper designing for this type of systems, in order to provide optimal reliability will be vital and expensive. This study examines the SCADA system in Tehran, which in the proposed model, the transfer of all or parts of the SCADA backup center in the cloud can cause the dramatic increase of reliability and reduce costs, and ensure the security of SCADA systems.
