Course Outline
Day 1: Foundations, Architecture, and Key Distinctions (ELK vs. OpenSearch)
Morning Session: Core Concepts & Architecture Review
- Introduction & History:
- Understanding the origins of the ELK Stack (Elasticsearch, Logstash, Kibana)
- The 2021 fork: Reasons behind OpenSearch (AWS vs. Elastic licensing changes, Apache 2.0 vs. SSPL/Elastic License) - Under the Hood (Shared DNA):
- Apache Lucene core engine: Shards, segments, inverted indices, and document storage
- Distributed cluster architecture: Nodes (Master, Data, Coordinator), clusters, and cluster state management
- Fundamentals of Data Ingestion and Processing:
- Logstash pipelines, Beats, and modern alternatives (Fluentbit, OpenTelemetry/Data Prepper)
Afternoon Session: Feature Divergence & Ecosystem Differences
- Security & Enterprise Features Comparison:
- Elasticsearch: Limitations of the free tier security vs. Paid features (SSO, advanced alerting, machine learning, cross-cluster replication tiers)
- OpenSearch: Out-of-the-box free fine-grained access control, internal user database, SAML/LDAP integration, and security plugins - UI & Query Languages:
- Kibana vs. OpenSearch Dashboards: Interface layouts, management tools, and developer experience
- Query Languages: Elasticsearch's ES|QL vs. OpenSearch's PPL (Piped Processing Language) and SQL support - Advanced Workloads (Vector Search & AI):
- HNSW implementations, k-NN search performance, and approaches to machine learning integration.
Day 2: Installation, Migration Strategies, Operations, and Troubleshooting
Morning Session: Installation & Cluster Setup
- Deploying OpenSearch:
- System requirements, kernel parameters (vm.max_map_count), and JVM heap tuning
- Bare-metal/VM installation via tarball and package managers
- Containerized deployment using Docker and Docker Compose
- Multi-node cluster bootstrap and security plugin initialization (opensearch-security-install) - OpenSearch Dashboards Configuration:
- Connecting Dashboards to the OpenSearch cluster
- Configuring SSL/TLS certificates and authentication backends
Afternoon Session: Migration Path, Operations & Best Practices
- Migration Strategies (ELK to OpenSearch):
- Assessing current ES version compatibility (optimal paths from pre-7.10/7.11 vs. newer versions)
- Snapshot & Restore Method: Using shared repository storage (AWS S3, NFS) for seamless data transfer
- Reindex-from-Remote & Logstash Rolling Migrations: Handling live data cutovers with minimal downtime
- API and client SDK adjustments (updating endpoints, connection strings, and client libraries) - Lifecycle Management & Operational Differences:
- Elasticsearch ILM (Index Lifecycle Management) vs. OpenSearch ISM (Index State Management) syntax and policies
- Strategies for rollover, shrinking, downsampling, and index retention - Monitoring, Backup, and Troubleshooting:
- Cluster health APIs, cluster stats, and tracking shard allocation issues
- Common failure scenarios (circuit breaker exceptions, JVM garbage collection pauses, split-brain mitigation)
Q&A and Wrap-up: Open forum for specific company migration roadblocks and architecture reviews
Practical exercises and Hands-On Labs will be a central focus of the course. Participants will gain experience with OpenSearch deployment, configuration, data ingestion, security, migration, monitoring, and troubleshooting through realistic, real-world scenarios.
Requirements
Participants should possess:
- Fundamental knowledge of Linux command-line operations.
- Familiarity with core networking concepts (TCP/IP, HTTP/HTTPS, DNS).
- A basic grasp of log management and monitoring principles.
- General awareness of containers (Docker) is advantageous but not mandatory.
- Practical experience with Elasticsearch or the ELK Stack.
