SaaS stands for Software as a Service, also known as On Demand Software. It is a software distribution model where a provider hosts applications and makes them available to a client over the internet. It is most commonly a subscription-based model, meaning that the client does not need to develop the software or purchase any perpetual licences. You cannot be non-compliant as you need only pay for the access you require.

SaaS delivers centrally hosted applications, requiring no maintenance or installation of the software by the client. A key or a login ID is usually all that is required to use the application. Costs are based on a pay-as-you-go type model linking to the profile of the user to set the access type and functionality available. Ideally, these flexible subscriptions mean that they can be cancelled when the application is no longer required. Ideal if you keep on top of who needs access and who no longer does. Applications come with a selection of modules, allowing you to tailor the profile of your users to subscribing only to the functionality required.

Examples of SaaS are:

  • Office 365
  • Google Apps
  • Salesforce
  • Skype for Business
  • Cisco Webex
  • Netflix

SaaS has changed the software industry. Vendors are no longer building on-prem software, they are either building new SaaS products or acquiring SaaS companies. The 3 most important factors for the move are cost, security and ease of use; with 38% of companies now running almost entirely on SaaS.

There is no doubt that using SaaS applications will have a fundamental impact on your company that will need to be embraced. Companies report a reduction in emails, fewer scheduled meetings and an increase in customer satisfaction. However, with its ease of use and purchasing, comes the issue of controlling costs.
