Consultants map data flows across SaaS applications, build reusable integration templates with error handling and retry logic, and implement monitoring that alerts teams before broken integrations impact downstream processes.

Consultants inventory existing ESB flows, design a migration path to lightweight API-led or event-driven patterns, execute a phased cutover with parallel running, and decommission legacy middleware to reduce licensing and maintenance costs.
