Visionary: Google

Google barely remains confined to the Visionaries quadrant, just a hair to low on the Ability to Execute axis to break into Leaders territory. Gartner estimates Google a distant third in market share, behind its two rivals in the Leaders quadrant: AWS and Microsoft.

Google Cloud Platform excels for big data applications, batch computing and cloud-native applications, according to Gartner.

The internet giant's strategy for growing its market share remains commercializing its well-known consumer technologies by delivering them as services. That's an enticing offer for cloud-native companies that want to "run like Google," said Gartner.
