Aiven for PostgreSQL vs CUBRID

Aiven for PostgreSQL is a managed, hosted relational database service built on open-source PostgreSQL. It automates setup, maintenance, patching, and scaling, and includes automatic failover and point-in-time recovery. The cloud service can run across providers including AWS, Google Cloud, and Azure. Aiven lists more than 50 PostgreSQL extensions, including PostGIS, pgvector, TimescaleDB, and pg_cron, and describes uses in vector search and AI applications. It can integrate with Aiven for Grafana and send metrics to external endpoints such as Datadog. The free tier has a single node, 1 CPU, 1 GB RAM, and 1 GB storage; it has no integrations or connection pooling and a max_connections limit of 20. That tier is excluded from the advertised 99.99% uptime SLA and receives no support services. The Free plan is free; Developer is $5 a month, Startup starts at $75 a month, and Business starts at $180 a month. Paid services include Basic support.

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.
