AWS Quick Notes — Elastisearch

Elastisearch is used to build applications that need search functionality. Search queries can be executed on various fields, partial keywords are also supported.

Typically data is loaded through built-in integrations from RDS/Dynamo/CloudWatch or Kinesis Data Firehose into ElastiSearch. Full text search capability can be then utilized to search for the data needed.

Scalability can be achieved by clustering.Multi-AZ is supported.

ElastiSearch, Kibana for data visualization and Logstash for ingestion of logs (ELK stack) can be used to analyze application logs.

Cognito based security is supported for authenticated users to be able to search directly.

Note : Amazon OpenSearch Service (successor to Amazon Elasticsearch Service) is a managed open-source search and analytics engine for use cases such as log analytics, real-time application monitoring, and clickstream analysis.
