Software-as-a-Service (SaaS) has been a primary driver of the transition to the cloud. According to the Blissfully SaaS Trends 2020 report, spending on cloud-based applications increased 50 percent from 2018 to 2019. The number of unique applications in use also increased 30 percent year over year, to an average of 137.
This was, of course, before the COVID-19 pandemic. The need to transition to work-from-home strategies has only accelerated the adoption of SaaS.
