Platform engineering at enterprise scale: lessons from the last 24 months
What separates internal platforms that get adopted from those that quietly become another silo.
Read article →The patterns in this article come from our work with large enterprises across regulated and fast-moving sectors. The aim is not to be exhaustive - it is to surface the handful of decisions we see making the biggest difference in practice.
1. Map the dependencies you forgot about
The hardest part of decommissioning is rarely the system you are switching off - it is the half-dozen integrations and shadow processes nobody documented. Investing in dependency discovery before you propose a date is the single biggest predictor of a clean cutover.
2. Strangle, don’t replace
Big-bang replacements rarely survive contact with reality. Routing traffic incrementally to the new system - feature by feature, segment by segment - keeps risk small and measurable, and gives you somewhere to fall back to if a release misbehaves.
3. Plan the data migration twice
The first plan is what you tell the steering committee. The second is what you actually execute, after you have profiled the data and discovered the duplicate keys, the orphan records and the optional fields nobody filled in correctly.
4. Decommission is a project, not an afterthought
Switching off the old system needs the same discipline as standing up the new one - including a date, an owner, a rollback plan and an audit trail. Otherwise legacy systems linger for years, costing money and slowing every adjacent project.
