Vendor Lock-In Risk Assessment

1. The team finds that 90% of the application's data pipeline uses AWS-specific services that have no direct equivalent in other cloud providers. What risk has the team identified?

2. The application uses a custom message queue implementation instead of a standard protocol like AMQP or MQTT. This means migrating away from the platform would require rewriting the entire messaging layer. What does this dependency represent?

3. The due diligence team estimates that migrating the application from its current cloud provider to a cloud-agnostic architecture would require 40 engineering weeks. This estimate is called:

4. A software company uses a proprietary AI API for all its NLP features. No open-source alternative provides equivalent quality. This dependency is flagged because:

5. The acquirer determines that the vendor lock-in risk is manageable because the proprietary dependencies are isolated in a single adapter layer, making a future migration feasible. What architectural pattern made this finding positive?
