Cloud & Legacy Data Engineering | Etherion Consulting

Modernizing legacy systems doesn't make them safer — it just moves the risk. We re-architect for auditability and independence, not just relocation.

Overview

Most legacy migrations are scoped as a technology swap: same logic, same dependencies, same undocumented workarounds, just running on new infrastructure. That approach carries every existing risk forward, adds new platform-specific failure modes, and frequently trades one form of vendor lock-in for another. Real modernization means re-architecting for auditability and platform independence.

What We Deliver

Legacy Migration Engineering

Migration off SQL Server and SSIS estates onto modern cloud infrastructure, without dragging undocumented risk along with it.

Cloud-Native Platform Build

Full-stack delivery across AWS, Databricks, Snowflake, GCP, and Azure — no proprietary frameworks, no vendor lock-in.

Governance Embedded in Code

Governance controls written into pipeline code using dbt Core and Apache Airflow — not maintained separately in spreadsheets.

CI/CD & Automated Testing

Pipeline deployment and automated testing built in from day one, so architecture stays clean, decoupled, and auditable.

✓ Engineering leaders modernizing legacy data estates under regulatory pressure
✓ Teams stuck with proprietary tooling or single-vendor lock-in
