Easily ensure high availability, protect data integrity, and meet the security and compliance standards for your mission-critical workloads. An integrated suite of cloud database services that allow you to address a wide variety of use cases, from transactional to analytical, from search to data visualizations. Launch secure mobile apps with native, edge-to-cloud sync and automatic conflict resolution. Run MongoDB anywhere, from your laptop to your data center.

Build flexible, distributed systems that can leverage the entire history of your critical data, not just the most current state. Build them on your existing infrastructure or jump straight to the cloud. Critical insights come from knowing the full story of your data, not just the most recent state. Datomic stores a record of immutable facts, which gives your applications strong consistency combined with horizontal read scalability, plus built-in caching. Since facts are never updated in place and all data is retained by default, you get built-in auditing and the ability to query history. All of this with fully ACID-compliant transactions. Datomic's information model scales to a wide variety of different use cases. With the Datomic Peer library, you can distribute immutable data to your application nodes to provide in-memory access to your data. Or, take advantage of the client library to create lightweight nodes for your microservice architectures.
