Overview

What this service delivers

Some core systems will be around for years. Platforms in banking, insurance and government often still use SOAP, fixed-width files and other older formats. We place a gateway in front of them that converts protocols, renames cryptic fields into clear ones, and adds caching and circuit breakers so a slow backend cannot bring down your website. When the old system is eventually replaced, only the gateway needs to change rather than every application that depends on it.

FAQ

Questions about this service

No. The gateway works with the system as it is, using whatever interfaces it already offers.

On your infrastructure or a managed cloud provider, close to the legacy system to keep response times low.

This is a remote technology service, so nothing is shipped physically. Work is delivered into systems you control. Read delivery and handover and refunds and cancellation for the full terms.
