What is SPIRE?

SPIRE (the SPIFFE Runtime Environment) is a production-ready implementation of the SPIFFE standards. It is a system that allows for workload attestation and secure identity issuance. SPIRE enables workloads to cryptographically prove their identity to each other, often used in cloud-native environments for secure service-to-service communication, eliminating the need for insecure secrets or IP-based trust. It provides a secure and automated way to manage identities across dynamic and heterogeneous environments.
