AWS Amplify Hosting now supports custom SSL certificates for custom domains. This new feature allows developers to easily upload and use their SSL/TLS certificates for their web applications hosted on Amplify, offering improved flexibility and security. With this feature, developers can now leverage certificates they’ve obtained from third-party Certificate Authorities (CAs) or use certificates issued by AWS Certificate Manager (ACM) to have greater control over your domain and IT compliance needs.
