In order to use Cloud computing, a company or user would have to connect to the internet, and that is not a problem since almost everyone can gain access to it.
However the problem is that the sometimes the internet can become interrupted or disconnected; meaning that the companies and people using Cloud computing could not work unless the internet was working and that would sometimes require technicians to become used to help solve the problem.
For companies this means that they are losing money and they would be wasting time for projects with deadlines.
Also, the speed of the internet can delay people working meaning that the company productivity could drop, and the company could be losing money when that happens. However the money that the company has saved can be used to get a better and faster internet service making cloud computing more efficient.
However, this will also happen to servers and this seems less likely to happen when you compare it to a server network.
Cloud computing may not be good for a lot of the companies, however it a great way for most companies to become productive and save a lot of money along the way.
