# When to create multiple systems
<a name="next-gen-when-multiple-systems"></a>

Create **separate systems** when:
+ Applications or services are independently operated by different teams.
+ You want separate resilience posture tracking for each application.

Use a **single system** when:
+ Multiple services work together to deliver business value.
+ You want to assess resilience across related services as a group.
+ Services share infrastructure (for example, a common Amazon EKS platform).
