Cloud computing provides an innovation platform beyond just cost savings. New technologies like containers, microservices, and APIs enable collaboration and mobility. Applications are designed to be stateless, transactional, and deployed atomically. This paradigm shift supports real-time scalability, insights from big data, and interconnected devices and people. Use cases include neighborhood watch, emergency response, and open data platforms. Cloud is impacted by mobility, social media, and the internet of things, moving away from silos towards collaboration across applications, data, and people.
