At present, we are all used to computing for some purpose or the other. In fact, all companies, businesses, organizations etc. no matter how large or, small are heavily dependent on computing to get their work done in a simpler and effective way. This is mostly about, storing, updating and sharing data among people within the organization and outside as well. Computing, for all the benefits that it offers, requires resources that can support the functions it performs. In the contemporary forms of computing, the user usually has to buy and store these resources which are mainly software, shared information / resource etc. Be it for short term utilization or long term, purchase and installation of necessary software is a must. Computing resources however, don’t come cheap. The users usually have to shell out a lot of money to avail the best of these, and storage of course, requires space which could otherwise be used for something more beneficial.
Cloud computing ensures that the user will no longer have to purchase the resource that he/she wishes to use for the sake of computing. They will also not have to store or, take the pain of installing and maintaining it all by themselves. Cloud computing is a service that people can hire. A user is required to contact a cloud computing service provider and ask for the particular resources that may be necessary for the job and leave the rest to them. The resource will be delivered to the user in exchange for a small fee (sometimes, it may not be required also), over some network. The most commonly used network to avail the delivered resources is the internet. Once the setup is complete, the service provider will be responsible for managing the resources on the user’s behalf. They will be of help and support any time and for any obstacle that the user may face. This can include maintenance, updating etc.
For the very reason that one can be free of making unnecessary purchase of software (that may be needed once and never again) the cost cutting factor comes into effect. This is liked by most companies, and small or large organizations tend to capitalize on the same. Besides this, enhancement of storage space is another substantial aspect of cloud computing. If availability of storage space is your concern, could computing can be an effective solution. The high level of automation is another factor that justifies the adoption of cloud computing by one and all. Computing in the cloud offers flexibility that many others will not be able to provide. The contemporary computing methods fall short when it comes to this characteristic. With all the main concerns about computing resource management taken care of, the IT professionals can actually put in time and focus on the work that they are meant to do (thus increasing job efficiency).
