integreringslager

Integreringslager is a term used in Nordic IT architecture to describe a dedicated layer or platform that enables integration of data and services across applications, systems, and external partners. It acts as middleware, focusing on data mapping, transformation, routing, orchestration, and governance. It typically includes components such as an enterprise service bus or message broker, API gateway, adapters or connectors to ERP and CRM systems, and a data transformation engine (ETL/ELT).

Functions of an integreringslager include supporting both real-time and batch integration, maintaining a canonical data model, and handling security, error handling, monitoring, and versioning. It provides a centralized environment for integration logic, enabling reuse of adapters and mappings across projects. Patterns commonly used are service orchestration, event-driven integration, publish/subscribe messaging, and schema mapping.

Implementation may be on-premises, in the cloud, or in a hybrid setup. It is often part of an integration platform as a service (iPaaS) or implemented with a combination of ESB, API management, and data integration tools. The layer sits between source systems and consuming applications, decoupling backend systems from user interfaces and analytics workloads, and it supports both operational and analytical data flows.

Role and benefits: an integreringslager improves interoperability, accelerates the addition of new systems, and supports standardized governance and data quality. It also enables scalability and reuse across projects. Challenges include complexity, cost, potential latency, security considerations, and the need for skilled governance and maintenance.

Related concepts include integration middleware, ESB, API management, and iPaaS. In practice, it is used to connect enterprise applications such as SAP, Oracle, and Salesforce with custom in-house systems, providing a cohesive integration backbone for large organizations.
