How a data team migrated its analytics to AWS with no downtime

A company ran its analytics on one cloud but wanted to move to AWS for cost and flexibility, without disrupting the reports the business relied on every day. Our team re-engineered the data pipelines and migrated everything across with no downtime.

Challenge

Move analytics to a new cloud without breaking the reports the business depends on.

What we built

Pipelines re-engineered for the new platform and migrated with validation.

Result

A clean cutover with no downtime, on a faster, cheaper platform.

The challenge

The company wanted to move its analytics to a different cloud for cost and flexibility. The risk was the reporting the business depended on every day. A migration that broke it, even briefly, was not an option, and a straight lift-and-shift would have carried old problems across.

What we built

  • Re-engineered the data pipelines for the new platform instead of lifting them across as-is.
  • Migrated the analytical schemas and historical data, validating the reports against the originals.
  • Cut over with no downtime, so the business never lost access to its numbers.
