Interlage

Interlage is a term used in information technology to describe a framework or approach for enabling interoperability across different system layers. In literature and practice, Interlage is not tied to a single product or company but denotes the architectural goal of connecting data, applications, and services that typically operate with distinct protocols, data models, and execution environments. The central idea is to create stable points of interaction that allow systems to exchange information and coordinate actions without requiring complete replacement or reengineering.

In an Interlage architecture, core components typically include middleware that mediates communication, application programming interfaces and API gateways that expose services, common data models or schemas that align disparate data representations, and event-driven messaging or service orchestration to coordinate workflows. Governance, security, and versioning practices are essential to manage interoperability at scale.

Applications of the Interlage approach appear in enterprise data integration, cross-cloud and hybrid environments, and Internet of Things ecosystems where devices and services from multiple vendors must work together. Benefits often cited include reduced integration costs, faster deployment of new capabilities, improved visibility across systems, and greater agility in responding to business needs. Challenges include ensuring data quality, maintaining consistent security posture, avoiding vendor lock-in, and managing evolving standards.

Interlage, as a concept, intersects with interoperability, middleware, API management, data governance, and architectural patterns such as service-oriented and event-driven architectures.
