Mulitple certificates vs. multiple domain names in one - AWS Certificate Manager

I just started using the AWS certificate manager and I was curious to see if there was a difference between creating multiple certificates, for example:

One for: mydomain.com
Another for *.mydomain.com

Or if it would be better to make one domain that contains both:

mydomain.com
AND
*.mydomain.com

Thanks!

Solution

  • If you want to use a single ALB or CloudFront distribution you will need to have these as a single certificate.

    Ideally I would use the single certificate for all domains as it easier to manage.
