What´s Cloud Computing?

Cloud computing is an internet based computing which provides various applications and services like storage, servers, infrastructure, networking with low cost, on-demand self service, pay as you go model, location independent resource pooling, reasonable price , rapid elasticity etc. Cloud computing is one way to increase the capacity add capabilities without investing in new infrastructures like computer hardware involves storage memory, licensing for new software, training for a person and in a dynamic way.

Cloud computing is innovative which uses well advanced computational power resource and gigantic improvement in storage capabilities, Cloud is the long dreamed vision of computing utilities, which helps in enable ling the sharing of resources and services over the internet. Cloud is a huge group of interconnected systems, which is a major change in how we store the large information and run application in time.

Cloud computing is a shared pool of configurable and well advanced computing resources, on-demand network access and is provisioned by the cloud service provider. The main advantage of cloud computing is a cost effective, Cloud computing is used by many software IT industries.

Clouds have a large pool configured easily available resources which are well accessible and usable resources such as hardware like desktops, hard disks, platform and services. These resources in the cloud can dynamically reconfigured adjust to variable scale, allowing for optimum resource utilization.

Cloud computing is a new dimension information technology (IT) and paradigm, which main aims to provide cost effective, reliable, customized and well guaranteed dynamic computing environment on “Pay-per-use” basis for the clients or end users....

...equire fewer maintenance because there is no need to install or upgrade software or hardware each and every time. Cloud mainly improves compatibility between the operating systems. It requires always on and high-speed internet connectivity for a single accessing also each and every time.

In cloud sometimes the data stored in the cloud server is so important that the clients who store their important data must ensure that it is not lost or corrupted. While in cloud it is easy to check the data integrity that whether their data is correct or not after completely downloading the outsourced data to be checked, downloading huge amounts of data just for checking data integrity is a waste of time for the client communication bandwidth along with this it also brings new challenging security vulnerability threats towards users outsourced data in the cloud computing system
