The history of cloud computing goes back a long way, to the 1960s, when time-sharing was first conceptualized in terms of remote job entry. The 'data center' model, by which users submitted jobs to operators for processing on mainframes, was mainly in use back then. This was the exploratory and experimental stage of finding various ways to make large-scale computing power available to more users through time-sharing, optimization of infrastructure, platform, and applications, and bringing about efficiency in services to end-users.

 Cloud computing refers to the on-demand availability of system resources-primarily data storage (cloud storage), computing power, without a direct active management by the user. Large clouds have their functions distributed over several locations, each location being a data center. Cloud computing relies on resource sharing, achieving coherence and often using a pay-as-you-go model, which can lead to reducing capital expenses but also to unexpected operating expenses for users.

IOT

Image
  Internet of things, abbreviated as IoT, refers to the network of interrelated devices which connect and exchange data with other related devices in addition to operating in the cloud. Typically embedded with sensors and software, it encompasses everything from mechanical and digital machines to consumer objects. It ranges from simple mundane household items to complex industrial equipment. Increasingly, organizations across sectors are using IoT to work smarter, enhance customer services, make better decisions, and add business value. Data in IoT is transferred over a network without human-to-human or human-to-computer interaction. A thing in the Internet of Things can be an entity with a heart monitor implant, a farm animal with a biochip transponder, an automobile with built-in sensors to alert the driver when its tyre is low or any other natural or man-made object that has an Internet Protocol address and can transfer data over a network.
