SaaS

• SaaS lets users try before they sign up for long-term contracts
• The pay as you go (PAYG) model proves very attractive
• Businesses can scale up or down based on operational and seasonal demand
• This model offers low risks but many benefits

Software-as-a-Service (Saas) is deployed over the internet and used by individuals or groups on a personal machine or local area network. Customers can often use software on a  “pay-as-you-go” basis by using the cloud provider’s licences, rather than buying licences themselves. This is why SaaS is sometimes called “software on demand”. In addition to  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.
