In order to facilitate testing and speed up verification, we have provisioned an Ansible Playbook that runs the steps directly on the clusters and validates that the deployment meets the requirements. Check below the execution of the playbook on our test environment.

Don't forget to configure the playbook variables with your test environment information (Figure 28).

Conclusion

We hope that this article has demonstrated that through the use of a distributed grid, it is possible to achieve quite satisfactory levels of heterogeneous data replication. We demonstrated that in addition to supporting clients that use the Hot Rod protocol, the Data Grid also offers a rich REST API that allows virtually any technology to connect to it and use many of its features. We also demonstrated one of the ways to configure a Data Grid cluster with high availability and real-time data replication, even in geographically distributed locations.
