Elasticsearch Training
Generic courses teach Elasticsearch in isolation. We train your engineers on Elasticsearch as it actually runs in production — with real data, real failure modes, and real operational trade-offs. Our instructors are the same engineers who manage large-scale clusters for clients daily, so every session is grounded in practical experience rather than documentation paraphrase. Training is delivered remotely or on-site, and always tailored to your team's starting point.
Fundamentals & Core Concepts
We start with the mental model that makes everything else click: how Elasticsearch distributes data across shards, how mapping decisions compound into long-term trade-offs, and how the Query DSL translates into actual Lucene operations. Labs use real data, not toy examples.
- ✓Cluster anatomy: master, data, coordinating, and ML node roles
- ✓Mapping design and field type trade-offs
- ✓Query DSL: from match queries through aggregations and nested objects
Advanced Topics & Production Operations
For engineers already comfortable with the basics, we run intensive deep-dive sessions on the topics that separate competent Elasticsearch users from genuine experts — the internals that matter operationally, taught under realistic pressure.
Cluster sizing, capacity planning, and hardware selection grounded in your actual data volumes and growth curve.
Cross-cluster replication and cross-cluster search — when they are the right answer and when a simpler alternative wins.
Zero-downtime upgrade procedures and version migration strategies rehearsed before you need them in production.
Red cluster, split brain, and OOM scenarios — engineers practice diagnosis and recovery under realistic pressure.
Custom Workshops for Your Stack
The most effective training is built around your actual situation. We review your existing indices, mappings, query patterns, and operational pain points before designing the curriculum — and lab exercises are constructed from your real data, anonymized where needed, so engineers are solving the problems they will face next week, not hypothetical ones. We have run this process for teams in e-commerce, fintech, media, and SaaS.
