A core replacement with no cutover weekend

A policy administration system three decades old, replaced slice by slice while carrying full production traffic.

Challenge

Atlas ran policy administration on a system whose behaviour existed nowhere but in the running code.

Approach

We reconstructed real behaviour from production traffic and carved the system into eleven slices behind a façade.

Outcome

First slice in production in four months. Full replacement in twenty-two, with no cutover event.

“There was never a night where the business held its breath.”

Behind the work

Practices and platforms used

Replace the system nobody wants to touch.

Infrastructure your engineers stop thinking about.

Enterprise data management and collaborative intelligence at scale.

One place where every team, in any industry, does the work.

A first conversation is with the engineers who would do the work - not an account manager.
