Elastic announced new capabilities and updates across Elasticsearch, Kibana, and Elastic Cloud in the 7.12 release. The new frozen data tier makes object stores like Amazon S3, Microsoft Azure Storage, and Google Cloud Storage fully searchable. The frozen tier decouples storage from compute, allowing customers to retain and search their data at a fraction of the cost while also reducing the number of dedicated resources needed for search. Users can also take advantage of autoscaling, available in technical preview, in Elastic Cloud on Kubernetes.
