I am a Power Platform specialist and one of the things I do regularly is tell clients that Power Platform is not the right choice for what they are trying to build. Honest fit assessment builds more trust than always recommending your preferred tool.
When Power Platform is not the right answer
High-volume, high-throughput transaction processing: Power Automate has throughput limits appropriate for business process automation but not for processing ten thousand records per minute. Azure Functions is the right answer.
Complex custom business logic: there is a point where the complexity of what you need to express in Power Fx exceeds what the platform is designed for. Custom application development is sometimes right.
Consumer-facing applications at scale: truly high-volume public-facing applications serving millions of anonymous users belong on Azure App Service or similar infrastructure.
When the organisation is not ready for the governance it requires: Power Platform deployed without the governance it needs creates real risks that accumulate quickly.
Sometimes the right recommendation is: not yet. Get the governance foundation in place. Build the CoE. Then expand. Doing it in that order produces better long-term outcomes.
The best technical advisors recommend the right tool for the problem. Honest fit assessment is worth more long-term than always advocating for your primary platform.
