Cloud computing is a concept that is internet based and enables information, software, and other resources to be shared on demand. The way in which the sharing works can be likened to the way a public utility works. A client leases what they require from a third party provider. Therefore they get only what is needed for the completion of their individual work projects.
One big advantage to a small business of accessing only what is needed at the time that it is needed is that initial capital outlay for end user licenses, individual work stations, and the like is considerably reduced. Thus there is little reason to outright purchase something that is merely required for special circumstances, monthly, or year end reports.
A further expense that is reduced by a business using the method of cloud computing is the need to acquire hardware for storing their database. Salaries for employing people to maintain that database and keep its hardware running are also reduced. The vendor that is chosen is the one who takes on that expense instead. It is the one who purchases and maintains the cloud of servers that stores what is required by its subscribers. Which often includes information that is necessary to maintaining operations of the business that is the customer.
What the user sees when he, or she, connects to the network they have their subscription with is often referred to as the front end. It consists of the client’s computer and the application needed to access the cloud computing system. Interestingly enough the kind of application used varies between providers. Some have separate applications altogether and others run through the web browser currently installed on the client’s computer.
The various computers, data storage devices, and servers are what is known as the back end of the cloud computing system. In theory those servers that are a part of the system could store for use any imaginable application. For example drafting programs, games, data processors, and a graphics application or two. Each program offered by a vendor is typically housed on its own dedicated server.
Backup data storage is also a typical and necessary redundancy that is built in to a cloud computing system. The reason for this feature is in the case of failure of the primary data storage system. Thus at least double the amount of storage used by a vendor’s clients is needed to store an exact duplicate of the data that is entrusted to them. Which allows clients to be as certain as possible that their precious information is secured from loss.
One advantage that cloud computing offers that is especially appreciated by those who are frequently mobile in their jobs is that their company’s data can be accessed from nearly everywhere there is an internet connection. So by its very nature computing through a cloud enables a project to be worked on almost without interruption.
Though privacy issues may concern some be aware that most of the incidences of data that has been stolen is the result of accident or carelessness on the part of a client. Cloud computing providers have a kind of pride in their reputations in keeping their customer’s information safe and secure and will work religiously to maintain them.
