In their own words
Microsoft SQL Server
Microsoft SQL Server is a database platform for storing, processing, and securing data, offered with both deployment models and a free plan. Its Database Engine includes replication, full-text search, relational, XML, and JSON data management, as well as Python and R machine-learning services. Integration Services provides graphical tools and programmable objects for moving and transforming data, while PolyBase can query Azure Storage, S3, and ODBC sources. SQL Server 2025 adds vector search, vector embedding generation, text chunking, and DiskANN vector indexing, and integrates with LangChain, Semantic Kernel, Entity Framework Core, Microsoft Azure, and Microsoft Fabric. Microsoft provides downloads for Windows and Linux and a SQL Server container image for Docker. Express is a free entry-level edition for learning and desktop or small server applications; its single Database Engine instance is limited to the lesser of one socket or four cores. Developer editions provide Enterprise or Standard functionality for development and testing, not production. SQL Server 2025 does not support SUSE Linux Enterprise Server.
TiDB Cloud
TiDB Cloud is a managed cloud database service built around an open-source distributed SQL database with MySQL compatibility. It supports transactional and analytical workloads, horizontal scaling, multi-region deployment, and geo-partitioning across Starter, Essential, Premium, and Dedicated plans. Starter includes up to 25 GiB of row storage, 25 GiB of column storage, and 250 million Request Units per month per organization, for up to the first five instances. Its on-demand compute scales to zero when idle, and vector storage and search are in public preview. CSV, Parquet, and SQL file imports are supported across the listed plans. Email and password login, SSO options, private and public endpoints, and console audit logging are listed across all four plans. Prometheus, Grafana, and Datadog integrations are listed for Essential, Premium, and Dedicated in public preview. All users can submit billing and account support tickets; guaranteed technical-ticket response times require paid support plans. The service is available through web and API platforms. Starter is free; the Dedicated plan is listed as starting at $0.22 a month and from $1376 / month.
