“It’s an honour to join Google Cloud at such a pivotal time in its journey,” Costello said.
“We have a tremendous opportunity to help businesses across the UKI and Sub-Saharan Africa harness the full potential of the cloud, from AI and data analytics to cybersecurity and sustainability. I am eager to build on the strong foundation already in place.”
The appointment comes as Google Cloud continues to expand its footprint in these regions.

In Sub-Saharan Africa, Google Cloud opened its first region in Johannesburg, South Africa, in January 2024, complementing its $1 billion commitment to supporting digital transformation initiatives across the continent.
