Elastic Cloud

Elastic Cloud charges based on deployment size, cloud provider region, and availability level, with costs layered on top of underlying infrastructure. Self-hosting on raw EC2 or Azure VMs can be cheaper at scale but requires your team to handle upgrades, security patching, backups, and cluster management.

Elastic Cloud is the official hosted offering from Elastic, the company behind Elasticsearch, while AWS OpenSearch is Amazon's fork created after Elastic changed its license in 2021. Elastic Cloud provides access to the latest proprietary Elastic features and full-stack integrations, whereas OpenSearch has its own separate roadmap and community.

Yes, Elastic Cloud supports vector search through its k-nearest neighbor (kNN) search capabilities, which are used for semantic search, recommendation systems, and retrieval-augmented generation (RAG) with large language models. Machine learning features such as anomaly detection and text embeddings are also available within the managed platform.

Elastic Cloud can be deployed on AWS, Microsoft Azure, and Google Cloud Platform, with the ability to choose specific regions within each provider. This lets organizations align their Elasticsearch clusters with existing cloud infrastructure and meet data residency requirements.
