Oracle GoldenGate Cloud Service

Even on Amazon AWS, for the migration of Oracle databases from on-prem to Cloud, my tool of choice is GoldenGate. The general steps I took for this migration was to create extract on source in on-prem, which sent data to replicat running in AWS Cloud in EC2 server, which in turn applied data to cloud database in RDS.




I was intrigued to see this new product from Oracle which is Oracle GoldenGate Cloud Service (GGCS).

So in this GGCS, we have extract, extract trail, and data pump running in the on-prem, which sends data to a Replication VM node in Oracle Cloud. This Replication VM node has a process called as Collector which collects incoming data from the on-prem. Collector then writes this data to a trail file from which data is consumed by a Replicat process and then applied to the cloud database.

This product looks good as it leverages existing robust technologies and should become default way to migrate or replicate data between oracle databases between on-prem and cloud.
