How should an organization design its certificate management strategy across multiple AWS accounts and regions?

Organizations operating across multiple AWS accounts and regions typically centralize certificate management using tools like AWS Organizations combined with automation, such as infrastructure as code templates that request and validate certificates consistently in each required region, while also monitoring certificate expiration and status across all accounts using AWS Config rules or CloudTrail based alerting to catch any certificate that might not be renewing automatically as expected.
