What is Amazon Elasticsearch Service called now?

Amazon Elasticsearch Service is now called Amazon OpenSearch Service, with the latest change on 8 September 2021 (Product Rebrand). Managed search, analytics, observability, and vector database service for deploying and operating OpenSearch and legacy Elasticsearch OSS clusters at scale. Only the customer-facing name changed; the underlying technical identifiers remain backward compatible.

Also known as

  • Amazon ES
  • OpenSearch Service

Technical identifiers

Technical identifiers unchanged. Only the customer-facing product name changed; the APIs, CLI commands, IAM roles and Terraform resources below keep their legacy identifiers for backward compatibility.

AWS Service APIs / SDKsopensearch es
AWS CLI Commandsaws opensearch aws es
IAM Actions & Policieses:*
Terraform Resources (aws_*)aws_opensearch_domain aws_elasticsearch_domain

IAM actions and domain ARNs retain the es:* namespace; AWS CLI and SDKs support both opensearch and legacy es clients for backward compatibility.

Notes & disambiguation

  • On September 8, 2021, AWS renamed Amazon Elasticsearch Service to Amazon OpenSearch Service alongside the launch of OpenSearch 1.0 (an Apache 2.0-licensed community fork of Elasticsearch 7.10.2 and Kibana 7.10.2).
  • For backward compatibility, IAM policy actions retain the legacy es:* prefix (such as es:ESHttpGet, es:ESHttpPost, and es:DescribeDomains) and domain ARNs continue to use arn:aws:es:region:account-id:domain/domain-name.
  • AWS CLI supports both the newer aws opensearch command namespace and legacy aws es commands, while the Terraform AWS Provider offers aws_opensearch_domain alongside legacy aws_elasticsearch_domain.
