In this paper evolution of IoT along with its intimacy with cloud is described. Application of IoT in various domains and the services are major research areas and can be enhanced further for more effectiveness and efficiency. Limitations associated with this technique are also addressed and appropriate solutions suggested. The future lies in the ‘Internet of Everything’. We have proposed a model which can be used in a wide collection of domains such as by Indian army, military, air-force, navy etc. The main focus of the proposed work is to evolve a combined approach (IoT + Cloud) into a single technology IoTC which will have the benefits of both the technologies and may overcome the shortcomings. It is beneficial in terms of space and time complexity, security, precision and accuracy of result. IoTC can further be applied to services of critically important services
