Case Study: Voxer achieves meteoric scalability and continuous write availability with Riak KV

Voxer Drives Meteoric Growth Powered By Riak Kv

Voxer, a San Francisco–based startup that combines walkie-talkie style voice messaging with group chat, experienced a viral surge after its Android launch—subscribership and usage jumped over 10,000%, and infrastructure grew from about 10 machines to well over 100—overwhelming their CouchDB backend. To meet the need for extreme scalability and continuous write availability, Voxer turned to Riak and its Riak KV key-value database.

Riak KV was migrated in under a week and scaled linearly to support between one and two billion transactions per day without losing a byte, keeping writes available even when many nodes failed. The Riak solution delivered the required high availability and operational simplicity—four people now manage the environment—and Voxer credits Riak (and its team) with reliable performance and strong support.
