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.

July 26, 2021
Just how vibrant is the enterprise-cloud market? We’re in the middle of earnings season and so far the numbers look mighty good:
  • Oracle reported huge gains across its Fusion cloud applications, OCI Gen2 infrastructure, and Autonomous Database;
  • SAP posted impressive gains across its cloud businesses, led by S/4HANA Cloud’s revenue increase of 39%; and
  • IBM said its last-12-months cloud revenue grew 13% to $27 billion.

This week we’ll hear from Microsoft, Amazon, Google Cloud and ServiceNow, and all indications point to each of those companies posting impressive results for Q2. In particular, Microsoft will be reporting its fiscal Q4 results, and for the past few years Nadella’s company has overachieved in the final period of its fiscal year—I certainly expect them to do so when their numbers come out on July 27.

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.
