New: IBM Cloudant on Transaction Engine

The best of NoSQL and SQL — strong consistency and hyperscale querying and storage

What is IBM Cloudant?

IBM Cloudant® is a fully managed, distributed database that is optimized for handling heavy workloads that are typical of large, fast-growing web and mobile apps. Available as an SLA-backed, IBM Cloud® service, Cloudant elastically scales throughput and storage independently. Our expertise takes away the pain of hardware and software provisioning, patching and upgrades, while offering a 99.99% SLA.

Cloudant's API and powerful replication protocol are compatible with Apache CouchDB to pair for hybrid or multicloud architectures.

Cloudant features


Instantly deploy an instance, create databases and independently scale throughput capacity and data storage to meet your application requirements.


ISO27001, SOC 2 Type 2 compliant and HIPAA ready. All data encrypted over the wire and at rest, with fine-grained access controls using IAM. BYOK and private service endpoints available.

Global availability

Cloudant is available worldwide and easily distributes data across availability zones, regions and continents for global application performance and disaster recovery requirements.

Zero vendor lock-in

Cloudant is the only fully managed cloud database service with an open source drop-in replacement in Apache CouchDB. Deploy them both in tandem for full hybrid and/or multicloud architectures.

Powerful API

Store JSON documents with an HTTP API. Enhance your applications with built-in key-value, MapReduce, full-text search and geospatial querying.
