What is meant by cloud computing

Hello sir, I am Vishal. I am from Mumbai. Can you tell me what is meant by cloud computing? Provide me some details about it.

[Raman Vij]

Cloud computing is a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications.

It is comparable to grid computing, a type of computing where unused processing cycles of all computers in a network are harnesses to solve problems too intensive for any stand-alone machine.

It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources

It relies on sharing of resources to achieve consistency and economies of scale, similar to a utility (like the electricity grid) over a network. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services

Working:

The aim of cloud computing is to spread over traditional supercomputing, or high-performance computing power, normally used by military and research facilities, to perform tens of trillions of computations per second, in consumer-oriented applications such as financial portfolios, to deliver personalized information, to provide data storage or to power large, immersive online computer games.

Cloud computing use networks of large groups of servers typically running low-cost consumer PC technology with specialized connections to spread data-processing chores across them.
This shared IT infrastructure contains large pools of systems that are linked together. Often, virtualization techniques are used to maximize the power of cloud computing.

Characteristics

Cloud computing exhibits the following key characteristics:

Agility
Cost reductions
Device and location i
Maintenance of cloud computing applications is easier
Multitenancy enables sharing of resources and costs across a large pool of users

Performance is monitored, and consistent and loosely coupled architectures are constructed using web services as the system interface.
Productivity may be increased
Reliability improves
Scalability and elasticity
Security can improve
