September 17, 2021: -Google Cloud CEO Thomas Kurian is shaking up the unit’s engineering organization in hopes of gaining market share more quickly.

Kurian announced several changes among its technical leadership in an email to staff Friday viewed by CNBC. According to the email, this includes replacing Eyal Manor, who has led engineering and essential Cloud products, including Anthos, for five years.

The email said that Manor, who has been at Google for nearly 15 years, will be looking for another role within the company.

Brad Calder will take over Manor’s responsibilities. A Google Cloud spokesperson told CNBC that Calder would also oversee security and data analytics in a more expansive role than Manor held. Calder will report to Kurian in a change that Kurian said will allow the technical teams to “work more closely with me and the Cloud leadership team, and Sundar and the Google leadership team” on longer-term strategy.

“With 15+ years of experience in Cloud, Brad has the proven expertise to take on a broader role to shape and drive the entire strategy” for Google Cloud, Kurian wrote.

ZDNet previously reported some aspects of Calder’s new role.

Pali Bhat, design and product vice president, will assist Calder with the transition, Kurian writes.

The shakeup is meant to help keep to grow Google Cloud’s market share while streamlining an organization that has ballooned in the previous several years since Kurian took over.

According to Synergy, with a 10% market share in the second quarter, the company trails well behind market leader Amazon, with 33%, and Microsoft, with 20%. It has made progress, though, since Kurian took over in late 2018. Google had about a 7% share as of the fourth quarter of 2018, Synergy estimated.

“We have an enormous opportunity to keep growing the business by expanding our total addressable market in new ways,” Kurian said in his email. “As the market changes, the needs of our products continue to evolve, and we must evolve our organization to support this growth.”

Kurian also said that Google Cloud Platform and technical infrastructure organization have more than doubled in the previous few years, and the “demands of shaping long-term strategy while focusing on the day on day operations have continued to accelerate.”

“As a result, we felt that it was the right time to unify the broad portfolio under Brad Calder,” his email said.
