Discover more about what's new at AWS with Amazon DocumentDB announces IAM database authentication

AWS' platform is a leading cloud computing platform, offering insights into cloud infrastructure, services, and solutions for developers, businesses, and IT professionals. Through articles, whitepapers, and documentation, AWS offers insights into cloud architecture, serverless computing, and machine learning on AWS. Developers and architects can learn about AWS services like EC2, S3, Lambda, and more to build scalable, secure, and cost-effective cloud applications.

Amazon DocumentDB now supports cluster authentication using AWS Identity and Access Management (IAM) users and roles ARNs. This feature allows applications on AWS EC2, Lambda, ECS, or EKS to authenticate without managing passwords, using IAM roles instead. Both new and existing clusters can use IAM for authentication alongside traditional password-based methods, provided they are MongoDB 5.0+ compatible. This is available in Amazon DocumentDB instance-based 5.0 clusters across all supported regions.
