Sound familiar?
- ▸ SSPL / ELv2 licensing block — legal flagged the Elasticsearch licence on your distribution, and the OpenSearch-vs-stay decision depends on ELSER, ESQL, and observability features you actually use.
- ▸ RAG architecture decision — should retrieval be ELSER, dense vectors, or hybrid? Embedding-model lock-in is real and you need a defensible call before committing to the pipeline.
- ▸ Cluster sizing is wrong — hot/warm/cold tier ratios were chosen by the original deployment, your retention has tripled, and the cluster is now over-provisioned in hot and under-provisioned in warm.

Strategic advisory — not execution
Elasticsearch Consulting Services
SSPL/ELv2 licensing strategy, Elasticsearch-vs-OpenSearch decisions, ELSER and vector-search architecture for RAG, cluster sizing, and Elastic Cloud vs self-managed economics. See the Elasticsearch hub for the broader services overview, or the ES-vs-OS comparison for the side-by-side decision matrix.
What our Elasticsearch consulting covers
Each deliverable is a written decision document, sized topology proposal, or costed trade-off analysis.
Licensing Strategy
SSPL/ELv2 impact analysis for your distribution model, ES vs OpenSearch decision with the feature-divergence matrix, and the migration math when licensing forces a move.
Vector Search & RAG
ELSER vs dense vectors vs hybrid retrieval, embedding-model selection, kNN index tuning (HNSW parameters), and end-to-end RAG architecture with Elastic as the retrieval layer.
Cluster Topology
Hot/warm/cold tier ratios, master vs data vs ingest vs coordinating node split, shard count and size targets, and ILM policy design for the retention curve.
Elastic Cloud vs Self-Managed
TCO modeling against your actual usage — vendor SLA + multi-cloud portability vs operator-based K8s deployment with reserved-instance economics.
Security & Governance
X-Pack Security configuration, RBAC role mapping, document/field-level security, IP filtering, audit logging — designed for your compliance scope, not blanket lock-down.
Ingest Pipeline Design
Beats vs Logstash vs Elastic Agent vs Fluent Bit decision, ingest-pipeline processor selection, dead-letter queue handling, and exactly-once semantics where required.
Observability Architecture
Elastic Stack for logs + metrics + traces + RUM + APM — when it's the right consolidated platform, when Grafana + Loki + Tempo wins, and the migration story between them.
How an Elasticsearch consulting engagement is shaped
1–2 weeks
Architecture Review
Deliverable
Topology recommendation, current-state risk register, shard/tier audit, sized remediation roadmap.
When to pick this
Running ES already and want a second-opinion audit before scaling or signing the next Elastic Cloud renewal.
1 week
ES vs OpenSearch Decision
Deliverable
Decision matrix with the feature-divergence list, TCO model for both, migration cost estimate.
When to pick this
SSPL/ELv2 is a blocker, or AWS OpenSearch pricing is forcing a re-evaluation.
2 weeks
RAG / Vector Search Design
Deliverable
Retrieval architecture (ELSER vs dense vs hybrid), embedding-model selection, kNN index tuning, end-to-end pipeline spec.
When to pick this
Building a production RAG workload and want the right retrieval architecture from day one.
2–3 weeks
Greenfield Design
Deliverable
Topology spec, capacity model, index lifecycle, security baseline, ingest pipeline design, ops runbook outline.
When to pick this
New Elasticsearch deployment and you want production patterns from day one.
