AWS Private Certificate Authority
#97 · Level 3 · Modern architecture · SecurityConcept
Section titled “Concept”With AWS Private Certificate Authority (AWS Private CA) you can create a private CA for your own organization. A CA (Certificate Authority) is the body that issues certificates and guarantees they are genuine. Certificates from a private CA are trusted only inside your organization; browsers on the public internet don’t recognize them. With them, internal servers, apps, devices and microservices recognize each other and talk safely. The CA’s secret key is kept in AWS’s secured hardware, and certificates can be issued together with ACM.
