RDS and SSL/TLS Certificates

Hello,

If your application makes use of SSL to connect to an RDS instance, only then will you be required to update your certificates on both the client and the RDS instance before the certificates expire.

It is not mandatory as the decision to make use of SSL is entirely up to you.

Since you are not using it, you are not required to update your certificates.

In future if you choose to make use of SSL in your application, you will need to update your instance to make use of the new certificate.

Hope this helps!
