Single-container deployments of n8n face issues like unresponsiveness and data loss under heavy workloads, prompting the need for a more robust architecture. The recommended solution involves using PostgreSQL for data persistence, Redis for job queuing, and dedicated n8n workers for parallel processing, all of which can be deployed efficiently using infrastructure as code with a render.yaml file. This setup provides benefits such as autoscaling, built-in security, and persistence, making it suitable for enterprise-scale operations while ensuring compliance with data sovereignty requirements. The architecture decouples workflow execution from the main UI, improving performance and reliability by introducing a queue-based system that allows for concurrent processing. The guide emphasizes managing critical components like encryption keys and binary data effectively and suggests using environment variables for credential management. It also highlights the importance of observability, recommending the use of native health checks to ensure uptime. Overall, this approach transforms n8n into a scalable, production-ready system, reducing the overhead typical of traditional VPS deployments and allowing users to focus more on building automations rather than managing infrastructure.
