A working demo is only one part of the journey. Production introduces architecture, integration, security, reliability, deployment, operating cost, and ownership questions.
Will it scale when real usage begins?
Is the architecture secure and maintainable?
Can it integrate with existing systems and data?
Can we operate it reliably in production?
What happens when traffic and data volume grow?
Are cloud and infrastructure costs under control?
Who owns deployment, monitoring, and operations?
Do we have enough senior technical capacity internally?
