The short version

A ten-year-old monolith moved to containers with zero downtime.

Outcome

42%

Lower monthly infrastructure cost

SC 01

The brief

Atlas ran on hand-built servers that one engineer fully understood. Deploys were monthly, stressful and done at midnight, and the cloud bill grew every quarter.

We were asked to move the platform onto modern infrastructure without a rewrite, without downtime and without the product team losing a sprint.

SC 02

What we did

01Mapped every service, scheduled job and secret on the old servers
02Containerised the monolith and described the whole stack in Terraform
03Set up CI/CD so every merge deploys to staging and production is one click
04Rehearsed the cut-over three times, then moved traffic gradually with no downtime
05Right-sized the infrastructure and added monitoring the team actually reads

SC 03

Design → code

One crew on both sides. The frame on the left is the Figma file; the panel on the right is the code that shipped. Type, spacing and colour carry straight across, and nothing gets lost in a handoff.
