Training Agenda

OpenSearch

OpenSearch is the open-source fork of Elasticsearch maintained by AWS — API-compatible with the Elasticsearch 7.x ecosystem but with its own development roadmap, AWS-native integrations, and an Apache 2.0 license. Teams running on AWS often choose OpenSearch Service (managed) over self-hosted Elasticsearch. This training covers OpenSearch architecture, query capabilities, and the differences that matter when migrating from or choosing between Elasticsearch and OpenSearch.

What We Cover
Search and analytics on the AWS-native Elasticsearch fork
Module 1

OpenSearch Architecture & Query

  • OpenSearch vs Elasticsearch: what changed, what is compatible, where they diverge
  • OpenSearch Service (managed): domain configuration, instance types, UltraWarm, Cold storage
  • Index management: ISM (Index State Management) — the OpenSearch equivalent of ILM
  • Query DSL: compatible with Elasticsearch — differences and additions
  • OpenSearch Dashboards: Kibana fork — discover, visualize, dashboards
  • Security plugin: fine-grained access control, encryption in transit and at rest
  • k-NN search: vector similarity search for ML embeddings
  • Anomaly detection plugin: real-time anomaly detection on time-series data
  • Alerting plugin: monitor definitions, triggers, destinations
  • Observability: trace analytics, log analytics, piped processing language (PPL)
Module 2

Migration, Ingestion & Production

  • Migrating from Elasticsearch to OpenSearch: API compatibility, breaking changes checklist
  • Data ingestion: Logstash OpenSearch output plugin, Fluent Bit, Firehose
  • OpenSearch Ingestion (managed Logstash): pipeline configuration
  • Integration with AWS services: CloudWatch Logs, S3, Lambda, Kinesis
  • OpenSearch cross-cluster replication
  • Snapshot management: manual and automated snapshots to S3
  • Sizing and performance tuning for OpenSearch Service
  • Cost optimization: UltraWarm and Cold storage for long-term log retention
Learning Outcomes
What your team walks away with

Teams who can operate OpenSearch confidently — whether migrating from Elasticsearch or building new on AWS — understanding the plugin ecosystem and AWS-native integration points.
