When you’re a fast-growing startup, you don’t realize how much your data stack limits you — until it does.
For years, the startup ran everything on Oracle. It worked fine — reliable, strong, enterprise-grade.
But as the team scaled globally, costs exploded, and flexibility vanished.
They wanted freedom — freedom to scale, to move workloads across clouds, to use open-source analytics tools, and to integrate data faster.
So they decided to migrate to PostgreSQL.
That’s when the nightmare began.......
The Hard Way:
They tried a few “migration solutions.”
Each came with its own chaos:
One tool worked for snapshots but broke during live sync.
Another required downtime every time a schema changed.
And one promised “real-time” replication… but lagged by 45 minutes.
The migration plan looked more like a postmortem report.
They needed something simple, real-time, and cloud-agnostic — something that could run on any cloud or even offline.
The Turning Point
That’s when they discovered Helyx — a lightweight, schema-aware replication engine that just worked.
It didn’t care whether the databases were on AWS, Azure, or GCP.
It didn’t need a GUI or 20-step config.
It ran from a single JAR file — and started replicating within minutes.
They connected their Oracle production system to a new PostgreSQL instance using Helyx,configured two property files, and ran:
java -jar helyx.jar \
--source oracle.properties \
--target postgres.properties \
--mode replicate
Within seconds, Helyx began streaming real-time change events from Oracle → PostgreSQL.
No lag.
No data loss.
No human babysitting.
Why Cloud-Agnostic Replication Matters
In 2025, data doesn’t live in one place.
You might have:
Oracle on-prem for operations
PostgreSQL in the cloud for analytics
MongoDB for app data
Replication between them shouldn’t depend on which cloud you’re using.
Helyx lets you replicate anywhere, anytime, without rewriting pipelines.
Key Takeaway
Cloud-agnostic replication isn’t just about portability — it’s about control.
It’s about owning your data pipelines without being locked into a vendor.
And that’s exactly what Helyx delivers — a fast, schema-aware, real-time replication engine that connects the old and the new, across any database or cloud.
