Microsoft Learn is Microsoft's own free training platform, with structured learning paths mapped directly to AZ-204 and every other Microsoft certification. Since it's produced by Microsoft itself, content alignment with the exam is about as authoritative as it gets, and the price — free — is hard to beat.
What Microsoft Learn doesn't do is track your individual readiness or adapt to your specific gaps. Modules are organized in a fixed sequence with knowledge checks at the end of each unit, but there's no diagnostic upfront and no evolving prediction of your pass likelihood as you progress.
Edureify's curriculum is built on the same Microsoft documentation and exam skills outline, but the Diagnostic identifies specifically which of Azure application development — compute, storage, security, and monitoring you're weakest on, and the roadmap keeps you there until your Readiness Score improves — which working through Learn modules in order doesn't measure.
