After three years at the helm of Google's Cloud business, Diane Greene announced Friday that she's stepping down from the role. She'll be replaced by Thomas Kurian, a longtime Oracle executive who recently left after reported disagreements with Oracle co-founder and CTO Larry Ellison.
In the second quarter of 2018, Google Cloud held an 8 percent share of the cloud infrastructure market, according to research firm Canalys. While it still trails AWS and Microsoft Azure, Google Cloud grew faster than both of its bigger competitors at 108 percent year-over-year.
"In a few short years, under Diane's leadership, Cloud has become an incredible business built on Google's decades of investment in infrastructure, data security, and AI," Google CEO Sundar Pichai said in a statement. "Today, those investments are available to everyone and truly changing the way people work."
Kurian, Pichai added, brings "product vision, customer focus, and deep expertise" to Google Cloud.
Kurian resigned from Oracle in September, after working there since 1996. He most recently served as president of product development and reportedly directly to Larry Ellison.
In that role, Kurian was responsible for leading software development and transitioning the company's technology to the cloud. However, his departure was reportedly preceded by disagreements with Ellison over the company's cloud strategy. Kurian reportedly wanted to let more of Oracle's software run on AWS and Azure, while Ellison opposed that in favor of promoting Oracle's own infrastructure.
In her blog post, Greene said she is stepping down as CEO "turn to the passions I've long had around mentoring and education."
Specifically, her work in education will focus on initiatives that combine technology with in-person teaching. The mentoring will include helping female founder CEOs who have engineering or science backgrounds.
