A move to AWS the customers never noticed

An accounting company moved its platform to AWS, built from scratch as code, and switched public traffic over without its customers noticing.

What we delivered

Step by step

1

Data gathering and design

We mapped what ran where and designed the target platform before building anything.

2

AWS infrastructure

A robust and scalable foundation built from scratch with ECS, RDS and Terraform.

3

CI/CD pipeline

A simplified, multi-stage pipeline on our own runners, connected to both environments.

4

Migration

Data mirrored between databases; after testing and validation, public traffic moved to AWS without customers noticing.

5

Secure connectivity

Non-production environments and all production admin services behind a VPN.
