The embeddable, high-performance database built for the edge and beyond

What is Informix?

IBM Informix is an embeddable, high-performance database for integrating SQL, NoSQL, JSON, time-series and spatial data. It powers your applications at the edge and beyond with:

  • High performance transactional processing: It processes +2M transactions per second with full consistency, concurrency, and resource utilization to support hundreds of thousands of users.
  • Always-on availability, clustering, and replication: Ensure advanced availability, active clustering, and cross-region replication for applications across the hybrid cloud.  
  • Seamless, embedded integrations: Run in the smallest capacity across devices and gateways, perfect for edge computing.
  • Hybrid cloud deployments: With a containerized version of Informix on the IBM Cloud Pak® for Data platform, you can more easily deploy on public, private or hybrid clouds.
