Riak

Developed in partnership with Basho Technologies and inspired by Dynamo, Riak SmartMachines are scalable, fault-tolerant, open source key/value database servers intended to be the primary data storage mechanism in production applications.

Riak images scale elastically and horizontally, allowing you grow your cluster from 3 nodes to 10 nodes to 100 nodes and beyond -- while your cluster is running. In addition to more storage space with added nodes, Riak images deliver a linear increase in processing power.

Riak images are:

• Built to operate in highly distributed environments, such as the cloud.

• Master-less - no single point of failure.

• Automatic data replication and read/write across all live nodes.

• Highly fault-tolerant due to its distributed nature

• Highly available for use in read and write-intensive web applications.

• Instantly scalable by adding a node to a cluster - with no downtime.

• Incredibly stable and trusted by some of the world’s largest companies

• Built-in, robust MapReduce engine for deep, complex queries

• Delivered with full-featured client libraries for, Java, PHP, Python, Erlang, and Ruby
