AWS Private Certificate Authority (AWS Private CA) is a managed service that provides users with the ability to create and manage private certificates for their internal applications and services. AWSPCA allows the issuance of private TLS/SSL certificates for securing communication between Kubernetes components, such as pods, services, and applications.
This service helps automate the lifecycle of certificates, ensuring timely renewal and revocation, thereby reducing the risk of security breaches due to expired or compromised certificates.
