According to Synergy Research that monitors Cloud market share, the enterprise SaaS market generated well over $23 billion of revenue for software vendors in Q1 and will hit a $100 billion annual run rate in the current quarter.
Microsoft reported $10.1 billion in Productivity and Business Processes revenue with a global market share of 17 per cent.
Salesforce was second with $3.74 billion in revenue and garnering 12 per cent market share. Adobe came in third with 10 per cent market share and $2.74 billion in revenue.
SAP and Oracle came fourth and fifth, respectively.
"The SaaS vendor landscape essentially breaks out into three camps traditional enterprise software vendors, relatively newborn-in-the-cloud players and large IT vendors that are looking to expand more into software markets," said John Dinsdale, a chief analyst at Synergy Research Group.
In the first camp are companies like Microsoft, SAP, Oracle and IBM that have a huge base of on-premise software customers that they can convert to a SaaS-based consumption model.
Born-in-the-cloud vendors include Workday, Zendesk, ServiceNow, Atlassian and Splunk, who tend to have much higher growth rates.
"Meanwhile Google and Cisco are making an impact in the SaaS market, via Google's G Suite and Cisco's collaboration apps and multiple software vendor acquisitions," said Dinsdale.
The top five SaaS vendors now account for just over half of the total market.
The next 10 vendors account for another 26 per cent of the market. Among these 10, the vendors with the highest growth rates are Google, ServiceNow and Workday.
While Microsoft's growth rate is diminishing due the massive scale it has achieved, over the last four quarters it has averaged 34 per cent, comfortably higher than the overall market growth rate.
"While SaaS growth rate isn't as high as IaaS and PaaS, the SaaS market is substantially bigger and it will remain so until 2023," said the report.
