AWS Certificate Manager (ACM)

  • Return to table of contents

  • Useful Links:

  • Exam Tips:

    • Certs CANNOT leave the region they are generated or imported in.
    • Need to be aware of the architect of ACM, not implementation.
    • Natively integrates.
    • Cannot use on EC2 instances.
    • For ALB with one site you must have a cert for each region.
      • E.g. An ALB in us-west-1 requires a cert in ACM us-west-1.
      • NOT cross-region.
    • CloudFront requires the cert requested in the US East (N. Virginia)
      • CloudFront is a global service and needs an ACM cert in us-east-1
    • Generate or import certificates.
    • Can automatically renew generated certs.
    • Supported AWS services only (e.g. CloudFront and ALBs, not EC2)
