Cloud computing is an approach to use a network of remote servers which is hosted on the internet to control, store and process data and not on a local server or a personal computer. It refers to sharing resources, information, and software through the internet.
With cloud storage, the user doesn’t have to store data on a physical hard drive, and this allows to access the data from anywhere, from any device laptop/tablet/smartphone and at any time. It also makes it easy for users who can parallelly work on the same document or presentation and make changes which streamline to get the work even when they are away from the office.
How do Cloud Computing Works?
Cloud computing services come in different types designed to fit different needs to suit different business/individual user’s needs. Some types of cloud computing services are designed exclusively for individual users to store documents, photos, and videos while there are other types of computing services that cater for companies to deliver infrastructure to develop IT applications. Cloud computing services are offered at a price. Fees can be paid on a monthly or yearly basis and price vary depending on the type of services you choose from the provider.
