"what is cloud computing exactly? why it is more popular today?" in Computer Software Classes
Hi Internet and Cloud are two terms that can be used interchangeably. Sharing resources like software, infrastructure (hardware) and platform (set of facilities required to develop and host applications or solutions) on pay-as-you-use basis like a service is called Cloud Computing. Hence the terms Software-as-a-Service (SaaS), PaaS and IaaS. Internet is the backbone of the delivery system. Since one doesn't have to own up things, investments in acquisition of services for personal or commercial purposes are just fraction of regular total ownership costs. Additionally, one doesn't have to worry about the maintenance, safety and security of the deliverables. Therefore, cloud computing is cheap, convenient and worry-free. That makes it popular too.
