Elastic, the company behind Elasticsearch, announced enhancements to its cross-cluster search and cross-cluster replication capabilities with interoperability between self-managed deployments and Elastic Cloud, now generally available. Customers can seamlessly search data across multiple Elasticsearch clusters deployed on-premises, on Kubernetes, and in the cloud.

Cross-cluster search enables users to search across multiple clusters and visualize data in one coherent view for deeper insights. Cross-cluster replication allows customers to replicate data between clusters regardless of their physical location (cloud or on-premises) and deployment model. Features include:

  • Streamlining workflows with a single user interface to search and replicate data between Elasticsearch clusters regardless of environment—on-premises, public cloud, hybrid, and multi-cloud.
  • Enabling customers to minimize risk and increase operational efficiency while retaining complete visibility of their data throughout the gradual migration of on-premises workloads to the cloud.
  • Optimizing customers’ ability to troubleshoot production applications, analyze security events, and manage where their sensitive data resides.
  • Improving disaster recovery scenarios where data redundancy and business continuity are critical, while increasing service resilience and lowering latency.
