Cloud Computing

Cloud computing is a technology which provides information resources and capacities to multiple customers through internet. It allows storing, accessing data and programs using the internet. Cloud computing provide users to store and process data in their privately owned space( called as cloud). There are broadly two types of clouds one can access :

* Public Cloud and
* Private Cloud.

Public Cloud

It is defined as a public or common cloud service provided to multiple users on a network. In a public cloud resources such as memory, hardware devices and network devices are shared by all the clients(called subscribers) and are called “tenants”.
Examples : Google Drive, Microsoft Onedrive, icloud etc.

Private Cloud

It is virtual private interface provided by an individual or owned by an organization. In this cloud all resources are dedicated solely to an organistaion. For example VPN( Virtual Private Network) is a private cloud that manages the security of the data during communication in the cloud environment.

IoT(Internet of Things)

Internet of things is a network of physical object or “things” embedded with electronics, software, sensors and network connectivity, which enables these objects to collect and exchange data. A thing is an entity or physical object that has a unique identifier, an embedded system and the ability to transfer data over a network. For example heart monitoring system, biochip transponders on farm animals, automobiles with built in sensors, DNA analysis device and other wearables, etc.

Components of IoT

Smart systems and Internet of things are driven by a combination of

1. Sensors
2. Connectivity
3. People and Processes

Internet of Things can connect devices embedded in various systems to the internet. When a device or object can represent themselves digitally they can be controlled from anywhere.
