GoldenGate for Real-Time Replication in Multi-Cloud Environments

Multi-cloud is the new normal. Analytics in one cloud, operational systems in another, and regulated data on-prem. But without real-time change data capture (CDC), you end up with stale dashboards, brittle ETL, and weekend cutovers that risk the business.

Oracle GoldenGate solves this with sub-second CDC replication and a managed service–OCI GoldenGate-so teams design and run pipelines without standing up infrastructure. It supports operational (HA/DR, active-active) and analytic use cases (streaming to lakes/warehouses) across Oracle and non-Oracle platforms.

Why GoldenGate for multi-cloud

• Heterogeneous, any-to-any: Replicate between Oracle DB and MySQL, PostgreSQL, SQL Server, Autonomous, plus modern targets like Snowflake, BigQuery, Azure Synapse, Databricks, object storage, and Kafka.
• Microservices + APIs: Web UI and REST for DevOps automation and policy-as-code deployments.
• Streaming integration: Native handlers to publish database changes directly into Kafka/Confluent/MSK/OCI Streaming.

Zero-downtime modernization

Migrate from legacy/on-prem to cloud (or cloud-to-cloud) with near-zero downtime. GoldenGate keeps source and target synchronized until cutover; you can even fail back. Oracle’s Zero Downtime Migration framework formalizes this pattern-incl. moves to Google Cloud.

Active-active, safely

For global apps that write in multiple regions, GoldenGate’s conflict detection and resolution (CDR) detects collisions and applies rules to resolve them (newest-wins, site-priority, custom). That keeps your records consistent without freezing innovation.

Real-world patterns we implement

• Cross-cloud analytics: Stream Oracle OLTP changes to Kafka → Snowflake/BigQuery for real-time dashboards.
• Blue-green upgrades: Upgrade databases or move to Exadata/Autonomous with continuous sync, then flip over.
• Hybrid intake: Capture edge/on-prem changes and land in OCI Object Storage, Synapse, or S3 for lakehouse consumption.
• HA/DR across clouds: Active-active between regions/providers with CDR to meet stringent RPO/RTO.

Bottom line: GoldenGate turns multi-cloud from “many copies, many problems” into one continuous, real-time fabric-for operations and analytics.
