The Informix service provides an Informix database on IBM Cloud Pak for Data, so you can use the rich features of an on-premises Informix deployment without the cost, complexity, and risk of managing your own infrastructure. Informix provides a high-performance engine that integrates TimeSeries, Spatial, NoSQL, and SQL data together with easy access via MQTT, REST, and MongoDB APIs.

Integrating an Informix database into Cloud Pak for Data can be useful in the following situations:

• You need an operational database that supports a rapidly changing data model.
• You want lightweight, low-latency analytics integrated into your operational database.
• You need to store large amounts of data from Internet of Things devices or sensors.
• You need to store and serve many different types of content.
