The Hidden Side of Cloud Migrations: FinOps at Scale

At Telkomsel, scaling cloud adoption across hundreds of workloads revealed a challenge that went far beyond technical execution: without visibility, governance, and alignment, cloud costs quickly became chaotic. As Indonesia’s largest mobile operator, they quickly realized that migrating to the cloud wasn’t just a matter of infrastructure: it demanded a cultural and structural shift in accountability, efficiency, and collaboration.

This session will explore what really happens after the migration, when the real transformation begins. We’ll share how Telkomsel embedded FinOps principles across engineering, operations, and application teams to create a culture of continuous optimization. From rethinking compute strategy to shifting team mindsets away from fixed-cost infrastructure, the journey shows that building cloud maturity isn’t just about scaling workloads, it’s about aligning people, processes, and financial discipline. Whether you’re early in your migration or deep in optimization mode, this talk will offer practical insight into turning cloud costs into a strategic advantage.
