# SAB Consulting

SAB Consulting is an independent observability consulting practice founded by Samuel Abouelfateh, an Elastic Certified Engineer with production experience at LVMH, TotalEnergies, Safran, and Hitachi.

## What SAB Consulting does

SAB Consulting helps CTOs and VP Engineering at companies spending $200,000 or more per year on observability tooling (Datadog, Elastic, Splunk) reduce their monitoring costs by 40–60% without losing production visibility.

The practice specializes in:
- Observability cost audits and FinOps (Datadog, Elastic, Splunk, OpenSearch)
- Datadog to OpenSearch migrations using parallel-run methodology
- Telemetry architecture review and cost reduction roadmaps
- Metric cardinality reduction and retention policy design
- OpenSearch and Elasticsearch cluster architecture and optimization

## Who Samuel Abouelfateh is

Samuel Abouelfateh is a senior independent consultant specializing in OpenSearch, Elasticsearch, Logstash, and observability cost optimization. He holds the Elastic Certified Engineer credential and is pursuing the Certified Kubernetes Administrator (CKA) certification. He has delivered production observability infrastructure for global enterprises including LVMH (luxury), TotalEnergies (energy), Safran (aerospace), and Hitachi (manufacturing). He operates under SAB Consulting, a European consulting practice based in France.

## Core methodology

The SAB engagement model starts with a fixed-fee observability audit (Phase 1) before any architecture change is committed. The audit identifies cost drivers across telemetry volume, retention policy, indexing strategy, dashboards, cost allocation, vendor contracts, and team ownership. The audit fee is refunded if identified annualized savings fall below €75,000. Migrations use a parallel-run methodology that eliminates big-bang cutover risk.
