Couchbase is a distributed document database (JSON), with all the desired capabilities of a relational DBMS; SQL, distributed ACID transactions; and much more. It is a hosted service and a product for hybrid (on-prem and cloud) deployments of mission-critical applications.
Couchbase has strived to reimagine the database, to serve the modern needs of application developers, instead of debating about SQL, NoSQL, or NewSQL. It is a robust database, built for microservices and serverless consumption-based computing on the cloud on one end, and edge computing for occasionally and locally connected edge Mobile/IoT devices on the other.
Couchbase’s distributed streaming architecture is designed for no single point of failure. This enables elastic scaling, resource fencing as well as instantaneous data replication for high- availability, global geo-distribution and disaster recovery. The result is a database that is resilient, cost-efficient, and built for metered usage. This cloud-native architecture combined with Kubernetes (K8s) delivers a self-managed autonomous database.

Developers write the JSON once into this database and apply multiple data processing capabilities on it. In addition to the full SQL programmability, Couchbase offers Caching, Key-Value store, Search (information retrieval), Analytics (Ad-hoc querying), and Event-driven (reactive) programming on this single copy of data.

Couchbase is designed to interleave transactions with these high-performance operations at large scale. Developers are offered the freedom to pay the price of a transaction only when needed. Consequently, Couchbase can serve as a reliable system of record, while concurrently handling key-value operations of microseconds latency, SQL queries and text searches in milliseconds, and Ad-hoc analytical queries spanning tens of seconds, one not impeding the other.

These are all capabilities that traditional databases cannot offer out of the box.
