This is the first part of a two-part series explaining how Vitrifi leverages NATS.io to build its Workflow Automation Platform. Some Background for Perspective At Vitrifi , we embarked on building a Workflow Automation Platform after discovering that existing solutions couldn’t meet our specific requirements. Our vision was clear - we needed a platform that would: Be fully BPMN 2.0 compatible Provide an intuitive interface for visually designing and simulating workflows Maintain a minimal footprint for deployment flexibility Dynamically scale task workers based on workload Support multi-cloud deployments with high resilience and scalability Process thousands of workflow states per minute with real-time status updates When existing open-source workflow solutions fell short, we took action.
