The World’s Top Cloud Vendors


The Cloud Wars ranking of the 10 most-influential cloud vendors in the world. We adjust the rankings regularly, so check back for fresh insights and updates.

April 6, 2020

As the United States moves into a 2-week period that will reveal the full horror of the COVID-19 crisis, and as Italy and Spain begin to move through the worst of the pandemic, we’re witnessing a worldwide phenomenon of public-private cooperation unprecedented in my lifetime. Over and over, as incredibly valiant healthcare workers battle to save lives and reduce suffering, and as researchers look to blunt the global power of the pandemic, and as heroic police officers and food-service workers put themselves on the line for the rest of us, we hear discussions of data, analytics, real-time insights, molecular modeling, supply-chain wizardry, and flexible and nimble logistics. We can hear echoes of the tech industry’s capabilities and contributions across the world as people from all regions of the world and all walks of life fight back against a silent, invisible, and highly lethal enemy.

And as that fight goes on, I want to continue our tradition of recognizing some of the outstanding contributions the companies in the Cloud Wars Top 10 are making:

The other day I heard someone cite this appropriate line from Winston Churchill: “When you’re going through hell, keep going.”

Words to live by here in April 2020.

Stay safe, stay strong, stay generous.

The media and some analysts perpetuate the silly myth that the cloud begins and ends with public-cloud Iaas. While IaaS is certainly important, it’s the software layers farther up the stack—PaaS and SaaS—that are driving even greater business value, innovation and differentiation for business customers.


Here at Cloud Wars, our Top 10 rankings are created from the POV of business customers, not from inside the tech-industry bubble.
