What n8n is and what role it plays in integration architecture
n8n is a workflow automation platform that enables flexible integrations, process orchestration and data flows between business systems. Unlike SaaS-only tools, n8n can be self-hosted in the organization’s own infrastructure, which provides full control over data and inference costs in AI scenarios.
In our delivery work, n8n most often acts as a second-level integration layer — used where the standard connectors of Power Platform are not sufficient and where the process needs custom logic, scripts or multi-step orchestration.
Self-hosted vs cloud
n8n can run self-hosted (Docker, Kubernetes, on-prem) or in the n8n.cloud version. The choice impacts data control, costs and regulatory alignment. In enterprise projects we more often recommend a self-hosted variant in Azure or in a private cloud.
Workflows as code and versioning
n8n treats workflows as objects that can be exported, versioned and deployed across environments. This matters for DevOps teams and organizations that need full control over the automation lifecycle.
Practical use of n8n in organizations
We most often use n8n to integrate scattered systems, automate end-to-end processes, orchestrate AI agents and run data flows between source systems and analytical platforms.
Scattered system integration
n8n provides practical flexibility where the organization uses many tools: CRM, ERP, ticketing, forms, marketing tools and external APIs. It allows building a connecting layer without rolling out heavy iPaaS-class solutions.
AI agent orchestration
In projects in the private AI and open-source AI agents area, n8n often becomes the orchestration layer for multiple agents. It calls LLMs, combines their outputs, escalates to a human and reports status. n8n is very well suited for this role.
Data flows and ETL
n8n is also used for simple ETL flows: pulling data from source systems, validation, transformation and loading into the data warehouse or into Power BI dashboards.
n8n vs Power Automate, Make and other tools
In practice n8n does not directly compete with Power Automate — it plays a complementary role. Power Automate dominates where the organization is anchored in Microsoft 365 and processes should run inside one consistent ecosystem. n8n becomes the choice where more flexibility, self-hosted control and non-standard integration logic are needed.
When to choose n8n over Power Automate
The most common situations are: the need to run custom scripts, missing connectors in Power Automate, integrations with legacy systems and orchestration of multiple AI agents in a hybrid model (cloud + self-hosted).
Combining n8n with Power Platform
In many projects a hybrid model works best: Power Platform handles the front of the process (forms, Teams approvals, Power Apps) and n8n becomes the integration engine on the side of source systems and AI.
When n8n is the right choice
n8n makes the most sense where the process requires flexibility, control and work with many systems.
when the process requires non-standard logic, custom scripts or legacy system integrations,
when the organization wants to run a self-hosted automation environment,
when n8n should orchestrate AI agents or hybrid flows,
when the DevOps team requires workflow versioning and full lifecycle control.
