A new era begins for OpenESB
The Enterprise Edition by VICO OPEN Modeling powers the future of enterprise integration.
Orchestrate, monitor and automate your organization’s systems on a single platform.
Integration platform designed by engineers. For engineers.
VICO OpenESB ENTERPRISE
Driving the future of enterprise integration: the platform that connects, orchestrates and evolves business systems.
VICO OpenESB Enterprise is a service-oriented and microservices-based integration platform that enables you to expose and consume RESTful APIs, connect applications, and integrate legacy systems into a unified and scalable environment.
Based on BPEL 2.0, JBI (Java Business Integration), and WS- standards*, it provides native support for RESTful APIs (contract-first design with OpenAPI) and combines the classic Enterprise Service Bus model with modern orchestration capabilities for cloud-native, on-premise, or hybrid architectures.
An essential tool for engineering teams that need stability, performance, and full visibility across complex environments.

Full Interoperability
Native RESTful APIs, SOA to implement microservices architectures, OpenAPI support and a wide catalogue of connectors to integrate legacy and modern systems.

Hybrid and Container Deployments
Full compatibility with Docker and Kubernetes, enabling distributed and scalable execution in hybrid or cloud-native environments.

Advanced Observability
Elastic APM and OpenTelemetry provide complete traceability of microservices, APIs and BPEL processes to detect anomalies and optimize flows.

Modern IDE with Eclipse + Oxygen XML Editor
An advanced environment for editing, debugging and validating WSDL, XML, JSON, and OpenAPI, with intelligent code autocompletion and support for XSLT 3.0 transformations.

Centralized Service Directory
A centralized module for managing and consulting enterprise services, monitoring instances and accessing catalogues with WSDL, XSD and OpenAPI definitions.

Modular and Decoupled Architecture
Based on JBI (Java Business Integration) containers that allow services to be deployed, maintained and scaled independently without disrupting the main system.

Declarative and Flexible Configuration
Define and manage flows using BPEL 2.0 and BPMN, with low coupling between services and high component reusability.

Java 21 (LTS) Support
OpenESB is fully compatible with Java 21, delivering better performance, stronger security and long-term stability through LTS support until 2031.

Security Standards & Monitoring Ready
OpenESB supports WS-Security, OAuth2 and JWT for secure service implementation and includes out-of-the-box Business Monitoring with native ELK integration.
We know the real challenges behind keeping everything connected.
- Each new tool or application added to the ecosystem increases operational complexity and becomes a new challenge for the IT team.
- Legacy systems continue to run in isolation and every patch or script connecting them to newer tools adds another layer of fragility and unpredictability.
- Cloud migrations often arrive without planning, extra budget or additional staff.
- Everyone expects data to flow, services to remain available and everything to “just work.”
- But behind every shiny dashboard, there are dozens of manual integrations, maintained with effort and creativity.

Key features of VICO OpenESB Enterprise
Observability and APM Integration
Monitor distributed processes and services in real time through native integration with Elastic APM. OpenESB Enterprise provides complete visibility of every flow, correlating traces, logs and metrics in a single dashboard to ensure consistent performance and stability.
- Auto-instrumentation with OpenTelemetry (OTel) to automatically capture performance data.
- Unified traceability of microservices, APIs and BPEL processes with full correlation of traces, logs and metrics.
- Proactive anomaly and bottleneck detection in real time.
- Root cause analysis down to code level for precise trouble shooting.
- Hybrid ecosystem monitoring: external APIs,legacy services and containerized microservices.
- 100% visibility and zero downtime, with observability as a core value of the system.
Modern IDE and AI Assistance
OpenESB Enterprise includes an advanced development environment based on Eclipse with the official Oxygen XML Editor plugin, enhanced by built-in artificial intelligence engines that boost productivity, code quality and development experience. A perfect combination of technical power and intelligent assistance for building, debugging and optimizing complex integrations.
- Advanced editing and validation of WSDL, XML, JSON, Swagger/OpenAPI and XSD.
- Step-by-step debugging and optimization of XSLT, with graphical support for complex XML/JSON documents.
- Intelligent autocompletion for XML, JSON, XSD and OpenAPI.
- Complete data transformations (XML ↔ JSON).
- Native OpenESB plugins to assist with BPEL process coding.
- Guided tools for project creation and configuration.
- Automatic BPEL code generation powered by integrated AI.
- Native Maven archetype–based project generation, fully aligned with CI/CD pipelines.
- Assisted correction and optimization of processes and services.
Modern Connectivity and Advanced Orchestration
OpenESB Enterprise offers open connectivity and native support for SOA and microservices architectures, allowing applications, APIs and legacy systems to integrate in a unified environment. Its BPEL 2.0 orchestration engine coordinates complex processes with full BPMN traceability, ensuring interoperability, control and efficiency.
- Native RESTful APIs for microservices architectures.
- Advanced JSON manipulationwith XSLT 3.0 for sophisticated transformations.
- Import and managementof Swagger/OpenAPI definitions with contract-firstsupport.
- Large connector catalogue(JMS, SOAP, JDBC, File, FTP, etc.) for integrating legacy and modern systems.
- Advanced orchestration with BPEL 2.0, enabling the definition and execution of complex processes that coordinate services and microservices.
- Full traceability to BPMN models, providing end-to-end visibility.
Centralized Service Directory
A central module to manage, consult and document enterprise services within a single ecosystem. It provides a unified view of all active integrations and simplifies access to service catalogues and definitions.
- Centralized monitoring of multiple instances within the same environment.
- Direct access to the organization’s public catalogue of available services.
- Download of service definitions and schemas (WSDL, XSD, OpenAPI) for documentation and reuse.
- Comprehensive visibility and centralized control over deployed services.

The Journey of OpenESB: from a community project to a global enterprise solution
OpenESB was born in the early 2000s within the Sun Microsystems ecosystem as an open-source implementation of the ESB model for the JBI (JSR-208) specification. After Sun’s acquisition by Oracle, the community -led by engineers like Paul Pérez- kept the project alive for more than a decade.
Today, VICO OPEN Modeling leads its evolution with VICO OpenESB Enterprise, a professional version with active support and its own roadmap.
Why trust VICO OPEN Modeling?
With more than 30 years of experience, VICO OPEN Modeling supports companies and institutions in their evolution toward open, interoperable and sustainable architectures.
