What is cloud computing?: So many times you may have heard of cloud computing and yet till now you are yet to know what exactly it’s all about. Imagine you are the CEO of a large firm and every time you hire a new worker, you will have to buy a new computer, and of course new software applications to install on the computer bearing in mind the number of licenses for each software. Cloud computing is simply a way out of this, because not only will it cost you money to buy and install software applications in every computer, it will also require technical capacities to maintain it. Imagine having a super computer somewhere with all this applications and even more installed in it and all you need to do is only to have access to it via an interface software which could simply be a web browser. This is the simplest explanation of the concept of cloud computing.
Cloud computing consists of two ends, the front end and the back end. The front end could simply be said to be the side of the computer user or client which includes the client’s computers and the application required to access the cloud computing system while the back end is the cloud section of the system. The back end includes the servers, data storage systems.
I know you may be wondering why will anyone want to rely on another computer to run his programs and store data? I will give you quite some reasons why:
– Clients can access their applications and data from anywhere in the world.
– Hardware costs will go down as there may be less needs for that. You wouldn’t have to bother much on repairs and maintenances of your computers, upgrade of hardwares and software applications .
– Companies will save more money on IT costs
– Work can even get easier as more people can now work on one project at the same time since they all can have access to the project.
There could be some challenges facing cloud computing as some are worried about the safety of the data they store in another computer. Cloud computing companies run backup always as no data can be lost. They ensure security system that will ensure that only authenticated users can access their services.
