Typical questions

FAQ

Q: How do I set up private mTLS certificates and PKI for secure communication between ECS services? A: You secure communication between ECS services by using the Certificate Management Service (CAS) to manage a private PKI, issue internal mTLS certificates, and deploy them to your instances. Next, configure ECS networking through security groups and ENIs. This setup enforces encrypted service-to-service communication across your VPC.
