EDB Postgres Distributed Always On: The End of the Reign of Oracle RAC
‘Always On’ is a hallmark of digital transformation. Digital businesses never sleep. Mobile apps, websites, IoT systems, social media, telcos, and financial services are operating 24x7. Hour-long maintenance windows are a thing of the past.
Databases are foundational for all of these services. Their High availability (HA) is constrained by what the database can support, through data replication. This whitepaper takes the reader through a discussion of what it means to be ‘Always On,’ what the obstacles are, and how bidirectional replication and EDB Postgres Distributed creates a PostgreSQL replication alternative to proprietary replication software, such as Oracle® Real Application Cluster (RAC).
