In 2022, Believe concluded that its legacy data centers were oversized and too costly. Following a call for tenders, a partnership was formed with Google Cloud. The idea was to start with a blank slate, breaking down the monoliths, and completely redesigning the technical stack to build a new, centralized system.

The cloud migration program was launched in January 2024. Accompanied by a Google integrator, the teams laid the cloud foundations. The migration to Google Cloud took place in three phases. The initial migration involved moving Believe's on-premises systems — applications, data, and services — to Google Cloud. This was followed by the gradual migration of its systems hosted on AWS (Amazon Web Services) to Google Cloud. Finally, the "all-in" migration was launched. This final phase finalized the transition by consolidating all of its activities and infrastructure into a single, centralized cloud environment.

"Moving to Google Cloud was a true clean slate that allowed us to rebuild a more efficient and faster system," explains Mona Roiff, VP at the CTO Office. The migration was accompanied by numerous transformations, including the introduction of a new coding language within Believe (Java), in addition to the existing one (PHP). This deep technological transformation also led to a redesign of the group's work methods. "The move to Google Cloud truly transformed our vision of tech," adds Mona Roiff. "Our CTO even wrote the manifesto for our new work method."

Believe considers the cloud migration a complete success. "We were supported with flexibility, kindness, and professionalism," emphasizes Mona Roiff. "We really see the difference; we now work much more efficiently and much faster."

Relying on a single provider generated significant economies of scale and productivity gains for Believe. Another benefit is that the group, which was already working closely with YouTube, saw its relationships strengthened, particularly through the simplification of data transfers.
