Redundancy

Redundancy is the duplicate capacity behind revenue-critical automations: how many replicas of a service exist, in which regions, and how current their data is.

The key distinction is whether that capacity is active (handling traffic in parallel), warm (running but idle, ready to take over), or merely theoretical (a diagram with no provisioned infrastructure).

A practical example

Example: a lead-routing service runs two active replicas in separate regions, so a regional outage shifts traffic without losing in-flight routing decisions.

What to evaluate before investing

  • Ask which redundancy tier your plan includes and whether warm or active replicas cost extra.
  • Request the regions where replicas run and whether data replication to them is synchronous or delayed.
  • Test or review evidence of a replica takeover, not just an architecture diagram.

Limitations and tradeoffs

Redundancy raises cost and can introduce data-currency lag between replicas, so the tier you pay for should match how critical each workflow is.
