Couchbase is a distributed NoSQL cloud database. It delivers versatility, performance, scalability, and financial value across cloud, on-premises, and hybrid deployments. It is available on the AWS Marketplace. However, it can be deployed on other clouds and on premise.
As a key-value and document database that’s memory first, Couchbase empowers developers to build responsive and flexible cloud and mobile applications that scale effortlessly.
• Flexible JSON schema for continuous delivery
• Easy, SQL-friendly query language for JSON
• Fully integrated SDKs for Java, .NET, Scala, Go, JavaScript, and Python
• Peer-to-peer-to-cloud syncing for mobile
Couchbase claims to be cheaper than DynamoDB at scale since the latter scales linearly and hence is more expensive at high volumes.
