Cloud refers to computing and storage capacity as a service. The name clouds derived from the shape of the complex infrastructure it contained including application, platform and infrastructure. The cloud providers maintain infrastructure and platforms which runs the end user’s application. Laptops, servers, desktops, tablets and phones can easily access clouds.
Cloud is considered to be a cheaper alternative for big data users who are looking for cheaper and efficient alternative to manage data. Cloud is replacing the need to maintain expensive and costly hardware on site to store data. Data is still stored somewhere but not at your place. If you a heavy user of storage capacity measured in petabyte and Exabyte, clouds is the way to store that data without buying and maintaining those expensive and labor and space intensive machines. The management of the content, sharing and access to data is given to a third party for efficient handling.
Cloud’s origin dates back to 1950s and still are in the early stages of content management and collaboration. Most of us are still using 25 to 30 year old e-mail system to communicate. Clouds allow all those involved to access and share information at the same time cutting the delay and increasing efficiency with heightened security.
