Oracle Global Data Services (Oracle GDS) provide dynamic load balancing, failover, and centralized service management for a set of replicated databases that offer common services. The set of replicated databases can use Oracle Distributed Database architecture, Oracle Real Application Clusters (Oracle RAC) and non-cluster Oracle Databases interconnected through Oracle Data Guard and Oracle GoldenGate.
Reduce or eliminate downtime and ensure business continuity.
Optimize database performance and resource utilization.
Simplify database management and reduce administrative overhead.
Enable global scalability and data sovereignty compliance.
Gain a competitive advantage with a highly available and resilient database infrastructure.
Global Data Services simplify database connections for applications. The services sit between your application and database tiers and helps direct application connections to the most appropriate destination.
Instead of connecting directly to a specific database, applications connect to an Oracle GDS, which then intelligently routes the connection to the optimal database instance based on factors such as:
Global Data Services manages this routing through two main components:
Active-Active Multi-Region Deployment with Oracle GoldenGate and Active Data Guard
Global Data Services is a highly effective solution for automatic workload management across a set of replicated databases. It consists of browser/mobile apps that work as an application tier. A Global Data Services configuration looks like a virtual multi-instance database to applications.
Applications within application tier reference a connection table which includes details on connection pools connecting to various databases.
A Global Services manager coordinates the application connections to databases. The service manager services database workloads and ensures that client requests are routed to the optimal instance that offers a service. It ensures high availability by transparently failing client connections over to surviving instances when a planned or unplanned instance outage occurs.
The databases in the database tier can be replicated and synchronized using Oracle Active Data Guard, Oracle GoldenGate, or Oracle True Cache.
Ensure business continuity during outages.
Utilize standby and replica infrastructure for serving workloads with intelligent workload routing and dynamic load balancing.
Deploy applications across multiple regions for optimal performance and data sovereignty compliance.
Simplify and de-risk cloud migrations with seamless database relocation and workload management.
