A Reference Architecture for Hybrid Integration

Kim Clark Integration Architect Offering Management

Digital Applications

Common use cases for hybrid integration within digital transformation

APIs

1

A. Join the API Economy B. Productivity C. Refactor for innovation

Automa,on

Enable new channels for revenue by monetizing

existing data via the API economy

Enable line of business to automate their own work across SaaS and existing

systems of record

Make a fundamental shift to a composable application

architecture, and cloud-based partners, to enable innovation.

Business projects are driving the “hybrid” agenda

Hybrid Integration Styles Combining app integration, api integration and data integration

Hybrid Deployment Software can be flexibly deployed on cloud and on-premises to optimize solution architecture

Hybrid Connectivity Reach across secure connections to get to data where it is from wherever you need

In a perfect world…

•  Application teams self-administer exposure of their own APIs

•  Access to external APIs is governed using the same mechanisms used to govern access to internal APIs.

•  Application teams handle their own integration needs using a productive subset of the tools available

•  Application logic is firmly seated with the application teams

•  API monitoring/diagnostics are gathered consistently across the organisation

•  Security models are implemented more consistently
