Every one talking about the cloud computing and when evr we think about the cloud computing lot of questions are coming in the mind like – What is cloud computing? How the cloud computing works ? Who provides cloud computing services? What is a public and private cloud ?
So many question comes in mind. In this post we will understand about the cloud computing. We will cover very basic aspects about the cloud computing.
People say that one picture is can be equal to 1000 page of book. Same here. If you are able to understand the above picture we will be able to understand the cloud computing.
I am sure you use electricity in your house. Have you think that where its produced, how its reaching to your house. You and so many peoples are using electricity and paying the amount. Basically end-user consume power without needing to understand the component devices or infrastructure required to provide the service
Same concept, Cloud computing provides computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services.
Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT’s existing capabilities.
One more thing I will must say – The cloud is not really a technology by itself. Rather, it is an approach to building IT services that harnesses the rapidly increasing power of servers as well as virtualization technologies that combine many servers into large computing pools and divide single servers into multiple virtual machines that can be spun up and powered down at will.
Now these days there are so many companies who proves the cloud services. You can take advantage of cloud from any of these companies.
Public clouds are shared infrastructures with pay-as-you-go economics.
Private cloud is infrastructure operated solely for a single organization, whether managed internally or by a third-party and hosted internally or externally
