MS Fabric is a data orchestration platform developed by Microsoft, but it has been criticized for its immaturity and lack of fundamental features such as source control integration. The platform has been plagued by issues including no recovery options, being locked into the Microsoft ecosystem, and a built-for-analysts-first developer experience. In contrast, Dagster is a unified control plane designed to address these concerns with an asset-based approach that provides end-to-end lineage, local testing, and a modern Python-based framework. Effective data platform architecture means prioritizing developer productivity, observability, self-service capability, resource optimization, and data quality assurance. Organizations should consider the true cost of choosing a platform beyond licensing and infrastructure, including lost engineering time, delayed business initiatives, reduced team morale, technical debt accumulation, opportunity cost, and career impact. Ultimately, architecture choices matter, and organizations should choose wisely between platforms like Fabric that are still figuring out their basics or one like Dagster designed from first principles to address the actual needs of modern data platforms.
