CLOUD COMPUTING
In cloud computing, IT resources such as servers, storage and software are not operated in-house, but utilised via the internet as required. These flexible services are billed according to usage.
Rather than making significant investments in their own technology (capital expenditure, or CAPEX), companies typically only pay for the services they use (operating expenditure, or OPEX).
This enables them to reduce costs and respond more quickly to changes.
It also makes IT more efficient and easier to access.
