AI-200 Blog
Guides, comparisons, and exam strategy for the Microsoft AI-200 (Azure AI Cloud Developer Associate) certification. 13 articles.
Curriculum Roadmap & Engineering Research Notes
The Microsoft AI-200 (Developing AI Cloud Solutions on Azure) exam represents a generational pivot from legacy developer exams. Rather than testing generic compute operations, AI-200 focuses heavily on modern container orchestration (Azure Container Apps with KEDA, Azure Kubernetes Service with Workload Identity), AI data platforms (Azure Cosmos DB NoSQL vector search, PostgreSQL Flexible Server with pgvector, Azure Managed Redis semantic caching), and distributed cloud observability via OpenTelemetry and KQL.
Our technical guides are engineered directly from verified laboratory deployments aligned with Microsoft Course AI-200T00-A. Each post explores the architectural trade-offs, configuration Gotchas, latency benchmarks, and scenario-based decision trees required to pass the exam and deploy production-grade enterprise AI backends on Microsoft Azure.
