Oracle GoldenGate Microservices Architecture

Oracle GoldenGate Microservices Architecture (MA) allows you to configure and manage data replication over homogeneous or heterogeneous database environments using RESTful services. These microservices can be accessed using various interfaces including a web interface, command line interface, REST API, or any other service that allows accessing REST-based microservices.

The following diagram illustrates the replication process cycle within a secure (HTTPS) or non-secure (HTTP) environment.

Features of Oracle GoldenGate Microservices Architecture

Oracle GoldenGate Microservices Architecture handles different tasks performed at different stages of the data replication cycle. Some of the product features include the following:

  • Oracle GoldenGate Microservices Architecture is bundled with utilities required to configure microservices associated with each deployment. See Components of Oracle GoldenGate Microservices Architecture.

  • It is designed with the industry-standard HTTPS communication protocol and the JavaScript Object Notation (JSON) data interchange format.

  • The architecture provides options to secure the data replication environment with a variety of security strategies including securing data at rest and in motion, TLS encryption, OAuth 2.0 authentication and authorization, integration with external user authentication services among others.

About Deployments

A deployment is a configuration to set up for Oracle GoldenGate Microservices to allow creating users, choose if you want to create a secure SSL environment, define the host and port for various microservices offered with Oracle GoldenGate Microservices Architecture. When you add a deployment for the first time, you can set up a new Service Manager and then add more deployments to the existing Service Manager.

What is a Deployment?

A deployment is a configuration package to set up Oracle GoldenGate Microservices for your choice of database. Deployments can be setup to be secure or non-secure and are added to a Service Manager.

Oracle GoldenGate Configuration Wizard (OGGCA) is a utility that allows you to configure your deployments. See the Add a Deployment topic to learn more about using OGGCA to configure various options associated with a deployment.

When you start the deployment configuration for the first time on the host server:

  • Decide if you need a secure or non-secure deployment. This is because you cannot change from secure to non-secure or non-secure to secure deployments after configuration.

  • Configure a new Service Manager on your host server. After the first time configuration, all new deployments should be added to the existing Service Manager available on the host server.

Note:

Oracle recommends that you have a single Service Manager per host server, to avoid redundant upgrade and maintenance tasks with Oracle GoldenGate releases.

Secure Deployment

If you decide to set up a secure deployment, then the deployment configuration provides you options to set up a secure SSL/TLS connection, using server and client certificates.

A secure deployment uses RESTful API calls over an SSL/TLS connection to transmit trail data between the Distribution Service and Receiver Service.

See Specify Security Options in the Add a Deployment topic, to learn about configuring security for source and target deployments.

Non-Secure Deployment

For a non-secure deployment, you don't need to apply server and client side certificates for the deployment. RESTful API calls occur over plain-text HTTP over the network.

Local and Remote Deployments

  • Local deployment: For a local deployment, the source database and Oracle GoldenGate are installed on the same server. No extra consideration is needed for local deployments.

  • Remote deployment: For a remote deployment, the source database and Oracle GoldenGate are installed on separate servers.
