Create versatile certificate and certificate authority (CA) configurations to identify and protect your internal resources, including servers, applications, users, devices, and containers.
Build on a solid security foundation to protect data, identify resources, and help meet your regulatory and compliance needs.
Avoid outages and improve uptime by automating CA and certificate management using API calls, AWS CLI commands, or AWS CloudFormation templates.
How it works
The diagram shows the key features of AWS Private Certificate Authority and the integrations available with other AWS services. Three sections display from left to right.
The first section has the title “AWS Private CA,” with an illustration of the AWS Private CA architectural icon and text that reads “Issue and manage private certificates.” This illustration points to another title “Private certificates” with text “Customize private certificates with any subject name, supported key algorithms, key sizes and signing algorithms, and validity periods.”
The second section has the title “AWS Certificate Manager,” with an illustration of the AWS Certificate Manager architectural icon, and the text "Provision and manage public TLS certificates." Above this illustration is another title "AWS CLI and SDK," with an illustration of gears, and the text "Automate certificate management in your environment of choice." These two titles point to the first section.
The third section is a branch off of the second section. The “AWS CLI and SDK” title from the second section has a double sided arrow pointing to this final section titled “AWS services” with explanatory text that reads “Use private certificates to secure communications on other AWS services.” There are four services and their respective architectural icons displayed: Amazon MSK, Amazon EKS, AWS IoT Core, and IAM Roles Anywhere. Directly below this are five small images with titles listed from top to bottom: VPN users, Service meshes, IoT devices, On premises, and Customer-managed Kubernetes.
