One of EnterpriseDB’s largest customers is a major Asian mobile phone provider with tens of millions of subscribers. In 2010 the company evaluated the aging data infrastructure that supported subscriber information and determined it required a major upgrade. 

Key agents of change were explosive growth in mobile phone use and the company's subscriber base, as well as the urgent need for backup and recovery should systems fail. The company required a more geographically dispersed system and examined replication solutions for distant backup centers that could be on active standby. 

The company’s systems were based on Oracle® and it first calculated an upgrade plan using the same solution. After careful analysis, the company determined a new, expanded system on Oracle was cost-prohibitive. Telecommunications companies are very cost conscious, as they are experiencing price pressures in a very competitive market. With cost control top of mind, the company explored open source alternatives. That led the database team to EnterpriseDB® (EDB™) and EDB Postgres Enterprise. The solution from EDB cost 75% less than Oracle estimates. 

Thus began a journey to liberate its system from their expensive Oracle DBMS platform -- a three-year project that included a hardware refresh, database implementation, and a backup and recovery configuration with a new off-site data center using EDB Postgres Failover Manager. The rollout of the disaster recovery architecture contributed to the lengthy time frame. 

Key also in choosing EDB Postgres Enterprise was database compatibility for Oracle, which enabled the company to migrate existing workloads to EDB Postgres Enterprise with minimal application refactoring. The company could continue to use their existing tools and DBAs, and developers could continue to use their Oracle skills, further saving the company in resources and training costs.
