About Viber and Couchbase

In late 2013, Viber, a fast-growing messaging platform, was pushed to scale at a rate their backend could no longer support. At the time, the company had deployed 300 nodes – mostly composed of NoSQL competitor MongoDB, in combination with Redis – to address their scaling issues. In 2014, Viber announced its switch to Couchbase given the massive growth and scale the platform was attaining. The company was drawn to Couchbase by its easy and transparent sharding and scaling model, ability to provide higher throughput, and reduced number of nodes required. Couchbase’s unique consolidation of caching and database tiers made the technology especially appealing to Viber. Today Viber continues to use Couchbase to serve 12% of the world’s mobile devices with always-available messaging.
