Cloudant NoSQL DBaaS Adds On-Premises Version

Cloudant, an IBM company, has introduced an on-premises version of Cloudant software that companies can install in their own data centers to run their own DBaaS.

The Cloudant database as a service (DBaaS) is a data management platform that leverages the availability, elasticity, and reach of the cloud to create a global data delivery network that enables applications to scale and remain available to users wherever they are.

According to the company, the addition of Cloudant Local (IBM Cloudant Data Layer Local Edition), provides customers with a strategy for managing application data with any mix of infrastructure and deployment strategy.

Launched in 2009, Cloudant designed its NoSQL database-as-a-service from the ground up to run in the cloud, using Apache CouchDB as the storage engine, with additional open source technologies layered on, and has developed monitoring and operations systems to ensure high availability and performance.

In 2014 Cloudant open-sourced the Cloudant Sync native mobile software libraries for Android and iOS, and this summer launched Cloudant Query, providing a declarative querying system that borrows syntax from MongoDB’s query system, and also introduced its first language-specific software library, Node.js for Cloudant. With Cloudant on the device and in the cloud, the company says, it is now completing the picture by bringing its service on-premises in the form of Cloudant Local.

Cloudant DBaaS and Cloudant Local are designed to run across a cluster of commodity server nodes. Nodes can be added and repartitioned as an application grows.

A typical Cloudant Local cluster requires four nodes to get started, for one load balancer and three database servers.The three DB servers are a default because Cloudant stores three copies of all records across different physical infrastructure. All writes are immediately committed to disk.

Cloudant is also providing tools and training for users on how to run their own DBaaS operation. More information is available at
