According to Gartner, SaaS (software as a service) remains the largest sector of the cloud computing market and is expected to grow to $117.7 billion in 2021 (a 16 percent increase). This is pretty impressive growth, which largely has been driven by the pandemic and the need for SaaS systems to support remote work.
SaaS has long been the red-headed stepchild of the cloud computing world. Most don’t consider SaaS as part of the cloud, focusing instead on IaaS providers, including AWS, Google, and Microsoft. This is largely because the SaaS world is widely distributed, with more than 5,000 SaaS applications out there, from bail bonds management to full-blown ERP systems on demand.
