ETSI Open Source MANO Announces Release EIGHTEEN, Continuing to Advance Declarative Infrastructure and Application Management

Sophia Antipolis, France, 09 September 2025

The ETSI Open Source MANO community is proud to announce OSM Release EIGHTEEN, a Long-Term-Support (LTS) release of OSM, meeting the established cadence of two releases per year and incorporating the latest innovations produced by the OSM Community.

OSM Release EIGHTEEN builds upon the architectural evolution of previous releases, further consolidating OSM as a cloud-native orchestrator for infrastructure, platforms, and services. This release introduces significant advancements in declarative operations, cluster management, and modular installation, reinforcing OSM’s position as a leading open-source orchestration solution.

OSM Release EIGHTEEN Highlights:

• Advanced Application Modelling: Introduces Applications as first-class entities using declarative, intent-driven models. Enhancements include:
  • Structured OKA blueprints for components, traits, and transformations.
  • Unified Argo Workflow for all App operations.
  • Support for multiple, optional KSUs per App.
  • New SDK for high-level, type-safe transformation scripting.
• Enhanced Cluster Management: Adds OpenShift cluster support and multi-node group management for AWS clusters, improving flexibility and scalability.
• New VIM Connectors: Includes a VMware vCenter plugin with VM console access, expanding IaaS support.
• Modular Installation: OSM installation is now modular and customizable. Airflow and MongoDB are integrated into a unified Helm chart, creating a single all-in-one OSM helm chart that includes all components.
• Service Assurance Framework Updates: Legacy POL and PLA modules removed; MON module simplified to retain only the dashboarder, aligning with long-term Service Assurance (SA) strategy.

OSM Release EIGHTEEN will be showcased in a dedicated webinar on Tuesday 16 September at 3:00 pm CET. Register here!
