# Clusters & Regions

> Learn about the available clusters and how they determine where your data is stored and processed

When you create a workspace, you select a cluster that determines where your data is stored and processed. This choice impacts data residency, compliance, and latency for your organization.

<Warning>
  **Cluster selection is permanent.** The cluster you choose when creating a workspace cannot be changed afterward. Make sure you select the correct cluster upfront.
</Warning>

## Available Clusters

<Note>
  If you bring your own Twilio integration into an EU workspace, only some Twilio API requests run in Twilio's Ireland region. See [Twilio integration > Regional API routing](/integrate-twilio#regional-api-routing) for the full breakdown.
