Document intelligence on AWS, integrated with an existing Azure estate

The organisation gained an AI capability without disruption to its core platform. The engagement produced a complete statement of work, cost model and target architecture for the production build.

Multi-cloudno disruption to the existing estate
Net-newcapability without forced migration

Customer background

A US healthcare services organisation providing patient access, prior authorisation and pharmacy support services to manufacturers and providers. The organisation's core platform is hosted on Microsoft Azure and was not a candidate for migration.

Challenge

An Azure-native organisation required AI document processing for patient access workflows. A full platform migration was neither required nor desirable, but the AI capability needed to operate on AWS.

Solution

Rather than proposing a platform migration, Rabbit Cloud scoped a net-new document intelligence layer on AWS using Amazon Textract and Amazon Bedrock, connected to the existing estate over private connectivity, with Amazon Macie monitoring the data landing zone.

Solution architecture

The engagement was delivered on the Document Intelligence Pipeline reference architecture, adapted to the client's data, security and operating requirements.
