Architecture and migration
Sizing, target environment, data transfer, cutover and recovery are resolved before production operations.

WZ-IT plans, installs and operates Node-RED as managed hosting, in your cloud or on premises. Depending on the target design, we also provide migration, secure network and identity integration, monitoring, backups, updates, integrations and further development.
The following are trademarks of their respective owners: Node-RED (the OpenJS Foundation). WZ-IT is an independent service provider and has no business, partnership, or contractual relationship with these companies. We offer independent migration, installation, hosting, and operations services.

Node-RED is a visual programming tool for wiring together hardware devices, APIs, and online services. With its browser-based flow editor, you can create complex logic by simply dragging and dropping nodes - perfect for IoT projects and home automation.
Built on Node.js's event-driven, non-blocking model, Node-RED is ideal for running at the network edge on low-cost hardware like Raspberry Pi as well as in the cloud. Its visual programming approach makes it accessible to users of any technical background.
We install, host and operate Node-RED for your company - either on our secure, privacy-focused infrastructure in Germany or other locations, as well as on-premise in your own environment.
We provide 24/7 monitoring, backups and maintenance for your Node-RED instance. Human response times and support coverage follow the selected service level.
Browser-based development environment for creating flows by simply connecting nodes without programming knowledge.
Over 5,000 pre-built nodes for various tasks - from input/output to complex data processing operations.
Embed JavaScript code in Function nodes for custom logic and data manipulation capabilities.
Efficient data storage and retrieval within flows using flow, global, and environment variables.
Robust error handling to ensure stable and reliable flow execution in production environments.
Comprehensive debug nodes for inspecting message payloads at various points throughout your flows.
Professional installation on your infrastructure - on-premise, cloud or hybrid
In your data center
AWS, Azure, Hetzner & more
Advanced architecture after technical and licence assessment
Secure access and access control for your installation
WireGuard, NetBird or Tailscale
Directly or through an upstream identity layer
Depends on application, edition and identity provider
Fail2Ban, Rate Limiting, IP Whitelisting
We set up secure VPN access to your installation - ideal for remote work and external employees.
Full-service installation with no hidden costs
Node-RED bridges visual programming and complex backend logic. The modular architecture allows us to develop custom nodes that seamlessly integrate into existing flows.
We control the Node-RED runtime programmatically: deploying flows, restarting instances, or dynamically adjusting credentials via API - ideal for multi-tenant systems.
Node-RED is natively asynchronous. We develop custom nodes that react to hardware events, MQTT messages, or database triggers and start complex logic chains.
When standard nodes aren't enough, we develop custom NPM modules. Packaged as native Node-RED nodes, with custom HTML configuration interface and performant JS logic in the backend.
How we implement Node-RED development in practice.
Old production machines speak proprietary protocols (S7, Modbus, serial interfaces) that modern cloud systems don't understand.
Node-RED as edge gateway translates local machine data, filters out noise, and sends only relevant metrics securely to the cloud via MQTT/HTTPS.
A frontend needs to query 5 different APIs, leading to load times and CORS issues.
A Node-RED flow aggregates all 5 requests in the backend, transforms JSON structures, and delivers a clean, consolidated response object to the frontend.
Non-technical employees should be able to modify automation rules (If X then Y) without calling the developer.
We integrate the Node-RED editor 'read-only' or restricted into your admin panel, so power users can visually adjust logic.
We do more than provide an application. WZ-IT designs the technical architecture, integrates network and identity, operates the agreed scope and develops integrations when the standard product is not enough.
Sizing, target environment, data transfer, cutover and recovery are resolved before production operations.
SSO, secure access, internal systems and existing security components are integrated appropriately.
Updates, backups, technical monitoring and response paths follow a transparent operational scope.
APIs, automation and custom extensions can be delivered beyond basic deployment.
The exact scope depends on the application, edition, infrastructure and criticality. Vendor licences and non-standard components are quoted separately.
Development and automation platforms need controlled execution, secrets, persistent data and clearly bounded connections to source and target systems.
Teams, repositories, webhooks, schedules and business systems initiate defined processes.
TLS, firewall rules, reverse proxies or private network paths are designed around the platform's exposure.
Local accounts, SSO, directories, service accounts and emergency access are connected through clear roles.
Editor, API, build or workflow runtimes are deployed reproducibly and isolated appropriately.
Metadata, configuration, source state, packages or execution history.
Queues, runners, containers, resource limits and separated execution environments.
Service accounts, secrets and controlled network paths to internal and external systems.
The diagram is a resilient target model. Its implementation depends on edition, data flows, load, availability objectives and existing infrastructure.
A clearly defined operating scope instead of an opaque hosting flat fee.
Compute, applications, storage and response are shown separately. You can see what ongoing operations include and which requirements need a technical assessment.
We also design custom Node-RED architectures, integrations and migrations. Contact us for a technical assessment.
One managed standard Node-RED application is included in the Starter workload. Every service level also includes flexible expert time for planned work during regular service hours. Select compute, additional applications, storage and the appropriate service level.
A workload is one compute instance with the applications agreed for it.
One standard app per workload is already included. Additional dedicated servers count as separate workloads.
€79.90 per started TB and month, including daily encrypted offsite backup with 7-day retention.
Briefly describe the current state and objective for Node-RED. We assess infrastructure, integration, and ongoing operations.
Whether you run Node-RED in-house or need to host confidentiality-professional data §203-ready - we build, operate and maintain Node-RED on an encrypted on-site server. Data never leaves the building in cleartext.

These solutions offer similar functionalities and can be evaluated together
These solutions are direct alternatives with similar use cases
No risk: worst case, you leave with a clearer understanding of your project than before.


“WZ-IT's advice on our Azure migration was technically sound and completely non-binding right from the intro call - we took away a great deal.”
Whether a specific IT challenge or just an idea - we look forward to the exchange. In a brief conversation, we'll evaluate together if and how your project fits with WZ-IT.
