Software-as-a-Service is software which is deployed over the internet and used by someone on a personal computer or local area network. Customers can often use software “pay-as-you-go” by using the cloud provider’s licences, rather than buying licences themselves – which is why Software-as-a-Service is sometimes called “software on demand”. As well as removing the need to buy, install and manage software at the user’s end, it also has the advantage of the software being accessible from anywhere with an internet connection.
