IT as a Service (ITaaS)

Part of the Software management glossary:

IT as a Service (ITaaS) is a technology-delivery method that treats IT (information technology) as a commodity, providing an enterprise with exactly the amount of hardware, software, and support that it needs for an agreed-on monthly fee. In this context, IT encompasses all of the technologies for creating, storing, exchanging, and using business data.

According to its proponents, ITaaS has numerous and diverse benefits including:

  • Minimal upfront IT investment
  • Regular, predictable expenses
  • Financial transparency
  • Tax advantages
  • Continuous monitoring of services
  • Expert technical support
  • Scalability
  • Regular software upgrades and patches
  • Guarantee of up-to-date hardware
