A look at open-source, high availability database replication
The End of the Reign of Oracle RAC: Postgres-BDR Always On
“Always on” is a hallmark of digital transformation, as digital businesses never sleep and mobile apps, websites, IoT systems, social media, and financial services are operating 24x7.
Databases are foundational for all these services, which means that high availability services are constrained by what the database can support, through data replication.
Access this white paper to explore a discussion of what it means to be “always on,” learn what the obstacles to high availability are, and discover how bidirectional replication and Postgres-BDR compare to proprietary replication software, like as Oracle® Real Application Cluster (RAC).
