As Europe’s leading entertainment provider, Sky has to stay a step ahead of constant technology challenges like streaming content, which put ever-increasing demands on their database. Frustrated with the scalability and performance limitations of their legacy Oracle RDBMS, Sky knew it was time to begin the transition to NoSQL and Couchbase when their data center reached capacity. They started by moving their identity platform, which provides full sign-up and sign-in functionality for all Sky’s online products. As part of their transformation, Sky embraced the use of distributed databases to cope with growing demand and spiky traffic patterns. Couchbase’s cross datacenter replication (XDCR) worked flawlessly for the data transfer to multiple data centers. In fact XDCR worked so well that Sky decided to use it to migrate all their data stores to Couchbase. The moves reduced sign-in response time by 50% and had huge implications for disaster recovery, dropping the recovery time from hours to minutes. Sky is now actively growing the Couchbase community within their company and looking for more ways to switch from Oracle to Couchbase.
