Digital Transformation (DT or DX[1]) is the use of new, fast and frequently changing digital technology to solve problems.

One of the examples of digital transformation is cloud computing. It reduces reliance on user owned hardware and increases reliance on subscription based cloud services. Some of these digital solutions enhance capabilities of traditional software products (e.g. Microsoft Office compared to Office 365) whilst others are entirely cloud based (e.g. Google Docs).
