The app is only part of the job. Here are the tools and connections Retter builds and looks after for this customer.
What Retter brings together.
| Part of the business | What we build and look after |
|---|---|
| Purchase-limit control | Backend enforcement of duty-free purchase limits, deployed on on-premises Kubernetes. |
| Stock control | Stock services running on AWS on Rio, connected to the retail operation. |
| Hybrid deployment | One backend team across on-premises and cloud, chosen per workload rather than one stack for everything. |
