Bob Evans sits down with John Siefert to unveil major shifts in the Cloud Wars Top 10 rankings in this first of a two-episode series. The discussion centers on why Google Cloud now claims the number-one position, Oracle surges to number two, and Microsoft slides to number three after a historic run. Evans explains how customer empathy, ecosystem strength, security posture, leadership vision, and forward-looking execution — not just financial performance — drive the rankings.

The Big Themes:

• The Cloud Wars Top 10 Is Holistic: The Cloud Wars Top 10 is intentionally designed to move beyond narrow metrics like revenue or technical benchmarks. As Bob Evans explains, the rankings reflect an amalgam of financial performance, innovation velocity, ecosystem maturity, leadership vision, and customer impact. This outside-in methodology evaluates how well vendors understand where customers are today and how effectively they help them move forward.
• Google Cloud’s Rise Reflects Customer Empathy: Google Cloud’s move from number two to number one reflects a long-term transformation rather than a sudden spike. Evans highlights how Google Cloud evolved from a technology-first organization disconnected from enterprise realities into a customer-centric platform under Thomas Kurian’s leadership. Empathy for customers’ existing environments, focus on sovereignty, security, compliance, and open ecosystems enabled Google Cloud to convert its technical strengths into market leadership and sustained growth.
• Oracle’s Momentum Is About the Future: Oracle’s move into the number two spot is driven by its success winning new, forward-looking business — particularly AI-driven workloads. Evans points to Oracle’s Remaining Performance Obligation (RPO) growth and aggressive go-to-market innovation. Oracle’s willingness to finance cloud expansion differently is framed not as weakness, but as strategic differentiation. Leadership continuity, operational experience, and a clear vision for AI infrastructure and data-centric cloud services are fueling Oracle’s ascent.

The Big Quote: “Nobody owns first place. You just rent it, and that lease can be pulled at any time if somebody else is doing a better job.”
