The Gartner Magic Quadrant ranks cloud vendors on two criteria: Ability to Execute and Completeness of Vision.
Execution is represented on the Y-axis of Gartner's chart, and vision on the X-axis. That lands competitors into one of four quadrants on the chart: Niche Players (low in both criteria), Visionaries (complete vision but lacking execution), Challengers (good execution but lacking vision) and Leaders (excelling in both vision and execution).
Among the 15 providers evaluated this year, none fell into the Challengers quadrant. And only industry powerhouses Amazon Web Services and Microsoft landed in the Leaders quadrant, leaving all others as Niche Players or Visionaries.
