While both the foundational cloud services market and the SaaS – Applications market are led by a small number of companies, there continues to be a healthy long tail of companies delivering cloud services around the globe. In the foundational cloud services market, these leading companies account for nearly three quarters of the market's revenues with targeted use case-specific PaaS services or cross-cloud compute, data, or network governance services. The long tail is more pronounced in the SaaS– Applications market, where customers' growing focus on specific outcomes ensures that over two thirds of the spending is captured outside the top 5.
