For high availability of OCI Functions executions across availability domains, what subnet choice does official guidance prefer when available?
Select an answer to reveal the explanation.
Short Explanation
A regional subnet is the wide safety net: executions can land across ADs without you enumerating one subnet per AD. HA here is an application subnet choice, not a second Functions product.
Full Explanation
Official Functions guidance prefers a regional subnet when one exists so executions can fail across availability domains without listing one subnet per AD. If you only have AD-specific subnets and need that resilience, you may name up to three. High availability is configured via the application’s subnet selection, not by inventing a separate Functions SKU or skipping subnets for detached invokes.
