Microsoft Launches SQL Server 2025, Fabric Databases, and Rebranded Azure DocumentDB

At today’s Ignite 2025 event, Microsoft announced one of the biggest Azure data updates in years. The company has announced the general availability of SQL Server 2025. That has come after a long preview period through 2024 and early 2025; the release is now production-ready. Microsoft, as expected, is relying heavily on AI-powered improvements within that cycle.

SQL Server 2025 adds native vector data types, approximate vector indexing for fast similarity search, and expanded JSON support. Copilot is also built directly into SQL Server Management Studio, which offers natural-language query help for developers working inside familiar tools.

It’s also worth noting that Azure Cosmos DB for MongoDB in vCore has also been rebranded as Azure DocumentDB, and it’s now generally available. The service includes AI-ready vector and hybrid search, autoscale capabilities, and independent compute-storage scaling. Microsoft continues to boast about its 99.995% SLA, paired with free 35-day backups for extra resilience.

Last but not least, Fabric databases are also generally available. SQL Database and Cosmos DB can now run inside Microsoft Fabric as a unified SaaS experience, combining real-time analytics, transactional workloads, and AI tasks in one governed environment.

Moreover, teams can keep their databases on existing systems can use Fabric’s database mirroring, which is also generally available, and supports SQL Server, Azure Cosmos DB, and Azure Database for PostgreSQL.
