Azure SQL Database vs CUBRID

Azure SQL Database is a cloud-native relational database service built on the SQL Server engine and delivered as a fully managed PaaS. Microsoft manages provisioning, patching, backups, monitoring, and high availability. The service supports standard T-SQL and can be accessed through the Azure portal, SQL Server Management Studio, Visual Studio Code's MSSQL extension, and compatible application frameworks. It supports native JSON and REST and GraphQL APIs through Data API builder. Hyperscale independently scales compute and storage and supports scale-out with up to 30 named replicas. For AI application development, it offers native vector search and connections to Azure OpenAI and Azure AI Search. It can connect to Azure Functions and replicate SQL data into Microsoft Fabric for near-real-time querying and analysis. Security and governance include a multilayered approach with Microsoft Defender for SQL; recovery features include disaster recovery and snapshot-based backups. The free offer allows up to 10 General Purpose databases per subscription, each with 100,000 vCore seconds, 32 GB of data, and 32 GB of backup storage monthly. Once limits are reached, a database can auto-pause or remain online with excess use billed at standard rates.

CUBRID is a free, self-hosted object-relational database management system for Internet data services. Its architecture combines a database server, a broker, and CUBRID Manager. Transactions support commit, rollback, and savepoints, with locking and logging for consistency. Backup methods include online, offline, and incremental options, while recovery can be partial or full. CUBRID HA synchronizes data between servers and can fail over when a master node fails, although the HA feature supports Linux only. The database supports read replicas and JSON data. Security documentation covers TLS-encrypted client connections, access control, authorization, and transparent data encryption. Interfaces listed include CCI, JDBC, PHP, ODBC, OLE DB, ADO.NET, Ruby, Python, and Node.js. Downloads include CUBRID Manager and the CUBRID Migration Toolkit. Installation documentation lists Windows and 64-bit Linux, requiring at least 1 GB of memory and 2 GB of disk space. The engine is listed at free.
