FlowMaster - Intelligent Job Orchestration Platform

Enterprise-grade batch job scheduling, orchestrated visually.

Inspired by BMC Control-M

BMC Control-M is BMC Software's flagship workload orchestration platform used in large enterprises to coordinate complex batch workflows across systems. FlowMaster recreates the same core concepts in a focused demo platform:

• DAG-based dependency orchestration and topological execution
• Cron-based enterprise scheduling
• Real-time operational visibility and execution telemetry
• Mainframe-style JCL import workflow

BMC Relevance

• Control-M alignment: FlowMaster models dependency-aware scheduling, cron triggers, and ordered batch execution exactly like Control-M planning/execution concepts.
• AMI alignment: live status feed + metrics timeline demonstrates the same operational observability mindset used in BMC AMI monitoring products.
• AMI DevX alignment: CI pipeline, containerized runtime, and API-first integration mirror DevOps workflows expected in modern enterprise mainframe delivery.
