More concretely a platform can be at different levels of granularity:
* CI configs and rules to be used by other teams
* IaC, tooling to deploy and monitor resources in the Cloud
* Development environment, tools and shared libraries
* Help and can define global system architecture / security
* Core abstractions (data model, business modeling) API/SDKs
